About JapanKoreaFXDefense
Japan and Korea both moved to defend their currencies on July 30. In New York, authorities were seen buying yen and selling dollars, pushing USD/JPY down 2.6% to near 159 after it hit its weakest since 1986. The won firmed 2% that day and over 8% across July. A record 11.73 trillion yen intervention in April-May had failed to hold the line. On July 31, the BOJ held its rate at 1% while warning core inflation runs above 2%. Neither government has officially confirmed intervening.

Japan and South Korea's Currency Shield Could Reshape Global Capital Flows
Japan and South Korea's coordinated efforts to stabilize the Japanese yen (JPY) and South Korean won (KRW) have become one of the most closely watched developments in global financial markets. After months of sustained U.S. dollar strength, both currencies faced mounting pressure, increasing import costs, weighing on corporate profitability, and prompting greater caution among international investors. The latest intervention signals demonstrate that policymakers are prepared to act decisively to curb excessive volatility and preserve financial stability.
For equity markets, a more stable currency environment often improves investor risk appetite. As foreign exchange volatility eases, capital tends to rotate back into companies with strong long-term growth prospects, particularly in the technology and artificial intelligence sectors, which continue to attract significant global investment.
Three stocks worth watching include:
$XNVDA: Continues to benefit from robust demand for AI GPUs, cloud computing infrastructure, and hyperscale data centers, reinforcing its leadership in the global AI boom.
$XAMD: Expanding its presence in AI accelerators and server processors, with growing expectations that it will gain market share as enterprises continue investing heavily in next-generation computing infrastructure.
$XTSLA: As a flagship growth stock, Tesla often attracts renewed capital inflows when global financial conditions stabilize and investor confidence in risk assets improves.
The implications extend far beyond the foreign exchange market. If pressure on the U.S. dollar continues to ease and global liquidity conditions improve, technology, AI-related equities, and digital assets could be among the first sectors to benefit. For investors, the latest moves by Japan and South Korea may represent an early signal that macroeconomic conditions are becoming increasingly supportive of growth-oriented assets once again.

Tolerance levels in multiple Asian countries have reached a critical point! A currency war is unfolding #日韩同日抛售美元护汇 $BTC
A rare scene in years during the New York session: Japanese and South Korean foreign exchange authorities simultaneously entered the market, selling dollars and buying their own currencies to defend them. The yen surged over 3% in the short term, and the won jumped 2%.
Many traders' first reaction: the dollar has peaked, and risk assets are broadly bullish.
But the vast majority overlook the core truth: joint intervention is a tactical defense and cannot reverse the medium- to long-term exchange rate trend dominated by interest rate differentials; short-term shocks tend to trigger pulse rallies, and blindly chasing the rally risks falling into the "one-day intervention rally" trap.
The biggest highlight of this action is not the short-term exchange rate fluctuations but the macro signal released by the policy coordination of two major Asian economies.
I. Core facts of the event
1. Mode of action: Japan and South Korea simultaneously sold dollar reserves and repurchased their own currencies. They chose the peak liquidity period in New York for a surprise attack, aiming to crush speculative funds that were unilaterally shorting the yen and won.
2. Background of intervention
The yen once approached a 40-year low, and the won fell to a multi-year low. The continuous malignant depreciation of local currencies brought two major pressures: soaring energy import costs pushing up imported inflation; increased burden of dollar-denominated debt on domestic companies, impacting financial stability. Verbal warnings had failed, forcing authorities to use real foreign exchange reserves to intervene.
3. Key details: The last coordinated intervention by Japan and South Korea dates back to the 2011 earthquake. After more than a decade, they joined forces again, indicating that single-country interventions are becoming less effective and must be coordinated to amplify deterrence. Market rumors suggest the US side simultaneously conducted exchange rate inquiries, forming an implicit policy tacit understanding.
4. Historical pattern review: Japan’s past large-scale forex interventions could quickly create short-term rebounds, but as long as the US-Japan interest rate differential does not substantially narrow, the exchange rate is very likely to return to the depreciation channel within weeks. Intervention can only change the rhythm, rarely reversing the major trend.
II. Four layers of deep logic to understand the real purpose of authorities’ actions
1. Defense is the priority, not actively pushing for sustained local currency appreciation
Japan and South Korea do not seek unilateral large-scale currency appreciation. Both are export-oriented economies, and sustained large appreciation suppresses export competitiveness.
The real goal: to end the one-way panic depreciation of local currencies, break the negative feedback loop of "the more it falls, the more it is shorted," suppress disorderly fluctuations, and buy time for domestic monetary policy.
Simply put: stop the crash, not start a long-term bull market.
2. Single-country intervention power is insufficient; coordinated action enhances capital deterrence
In the past, Japan’s solo interventions allowed speculative funds to continue betting on depreciation in batches. Japan and South Korea acting simultaneously forces shorts to hedge against two Asian currencies at once, raising capital costs and risks simultaneously, thus more effectively suppressing speculative forces in the short term.
3. Hidden monetary policy contradictions: intervention treats symptoms, interest rate differentials are the underlying constraint
The root cause of the yen’s continuous weakness: the Federal Reserve’s high interest rates and the long-standing US-Japan interest rate differential.
Forex intervention uses existing dollar reserves and cannot change the benchmark interest rate gap between the two countries. As long as the interest rate differential remains, carry trade funds still have motivation to keep selling yen.
This is the biggest shortcoming of intervention: without monetary policy cooperation, the sustainability of the rebound is inherently limited.
4. Global exchange rate pattern signal: the strong dollar has become unbearable for many countries
Not only Japan and South Korea, emerging markets have long suffered from the impact of a strong dollar. This coordinated intervention marks a symbolic event that global tolerance for a strong dollar has reached a critical point. If the dollar continues to strengthen, more countries will adopt measures to stabilize their exchange rates.
III. Chain transmission and deduction of major assets
1. US Dollar Index
Under short-term pressure, it forms a pulse-like weakening.
Two scenarios:
① Short-term sentiment rally: after intervention impact fades, funds re-trade Fed rate expectations, and the dollar recovers again;
② Necessary condition for sustained weakening: subsequent US inflation and employment data cool down, and rate cut expectations continue to rise.
Relying solely on Japan and South Korea’s intervention is insufficient to drive the dollar into a medium- to long-term bear market.
2. Gold
Short-term benefits from dollar pullback rebound.
Medium- to long-term trend still anchored to real interest rates. The dollar’s phased decline provides a buying window, but do not rely solely on intervention news to bet on a long-term gold surge.
3. US Nasdaq
Risk appetite is temporarily boosted. Growth stocks are highly sensitive to the dollar and US bond yields, prone to short-term spikes.
Beware of bull traps: intervention is an external exchange rate event and cannot change the fundamentals of the US economy and corporate earnings. After the pulse rebound, the market returns to earnings reports and Fed policy as the main themes.
4. Crude Oil
Pulled in two directions. Dollar decline theoretically benefits commodities; however, the currency stabilization by Japan and South Korea reflects global economic pressure, and forward demand expectations are suppressed, likely entering a range-bound phase.
5. Cryptocurrency (Bitcoin)
Follows risk appetite with short-term correlated movement.
Key rule to remember: intervention-driven rallies generally have weak sustainability. Do not mistake short-term pulses for the start of a new trend. Continue to monitor dollar liquidity and ETF fund flows.
IV. Three major market traps traders must beware of
1. Misconception one: joint intervention = dollar trend peak
Intervention is an external disturbance; monetary policy is the core of long-term exchange rate pricing. Do not bet on a long-term dollar bear market based solely on this news.
2. Misconception two: blindly chasing short-term sharp rises
Many historical cases prove that intervention-induced surges often "come fast and retreat faster." Shorts are forced to cover, pushing the rally, but after covering ends, there is a lack of new buying support.
3. Misconception three: believing authorities will indefinitely continue to deploy reserves
Foreign exchange reserves are limited resources; sustained large-scale consumption has a bottom line. Once the exchange rate stabilizes, the willingness for further large-scale continuous intervention will significantly decline.

South Korea reportedly made a rare dollar sell-off, with traders suspecting joint intervention by Japan and South Korea in the foreign exchange market
On July 31, market sources revealed that South Korea's foreign exchange authorities carried out a rare dollar sell-off intervention on Thursday, pushing the Korean won to a nine-month high. This action by South Korea coincided with Japan's intervention in the New York market on Thursday, where it bought yen and sold dollars, pulling the yen back from a forty-year low. The won appreciated 2% against the dollar on Thursday, reaching 1 USD to 1418.0 KRW, the strongest level since October 20 last year. The won had hit a 17-year low of 1561.50 last month and has risen more than 8% this month, poised to record the largest monthly gain since March 2009. A South Korean finance ministry foreign exchange official declined to confirm the intervention. A South Korean forex trader said the market suspects a joint intervention by South Korea and Japan, as the two countries had previously stated they would closely coordinate. On July 2, the South Korean Deputy Finance Minister said at a press conference that Seoul is maintaining close communication with Japan and other major allies on foreign exchange issues. Japan's top foreign exchange official followed up on July 7, stating that Tokyo is in close communication with Seoul's foreign exchange officials, citing that the financial markets of the two countries sometimes show similar volatility patterns.
Today's market reminds me of an idiom
It's called 'blind man touching an elephant.'
Everyone is talking about their own direction
But no one could see the full picture
BTC fell, ETH fell, and SOL also fell
However, the declines varied
I stared at the market all morning without doing anything
This is a typical bystander mentality
Then guess what.
KOSPI in South Korea has activated its sidecar mechanism to suspend programmatic trading for 5 minutes
This action itself is a signal
When a market needs to pause and calm down
This indicates that the fluctuations have already exceeded the normal range
The Korean won appreciated 2% against the US dollar to 1,418
This is a rare intervention by South Korea's foreign exchange authorities
The yen is also strengthening
This indicates that global forex markets are fluctuating
Cryptocurrencies have shown relatively resilience against this backdrop
Leveraged ETFs for Korean bonds are also the hardest hit by this volatility
The finance minister's public apology shows the seriousness of the issue
Leveraged ETFs were designed to amplify returns
But under extreme volatility, it also amplifies risk
The lessons of this product in the Korean stock market are worth learning from for all markets
The crypto market also has similar products
High leverage is always high risk
So my judgment is
Today's decline is part of a global shift in risk appetite
It's not just a matter of encryption
Once KOSPI's stabilization mechanism takes effect
Market sentiment will gradually recover
There are a few more noteworthy topics today, so let's talk about them together:
#微软单日市值增近4500亿, setting a record for the US stock market
The escalation of the US-Iran conflict has pushed up oil prices, but the increase has been very limited
The market is more concerned about rate hike expectations than geopolitical risks
This reaction indicates that oil has been weakened financially
I don't think this temporary geopolitical tension will continue to push oil prices higher
More importantly, oil price fluctuations have little impact on crypto liquidity
#HYPE再遭亿元解押, Japanese companies entered the market for the first time
HYPE's uncollateral release and share reduction have put pressure on the entire ecosystem
Whale cashing out means short- to medium-term liquidity release

Influential Creator
Yesterday, I briefly discussed Japan and South Korea from a geopolitical perspective. But after just one day, both countries simultaneously rescued their markets. Everyone knows Hynix has surged, but the yen exchange rate has attracted less attention from the stock and crypto circles, but the intensity is just as fierce.
After last year's tariff war, the yen surged from 140 to 160+, recently reaching a peak close to 164. I remember two years ago, Ni Da@PhyrexNi and I even made a bet on whether the yen would get closer to 160 or 130 in October 2024. However, Japan still had strength that year, and the yen was still fluctuating within a wide range, which was completely different from today's one-sided depreciation.
The core problems for Japan and South Korea are actually their industrial chains being dismantled by China and the US. In particular, many of Japan's original advantageous industries have been caught up by China and have lowered profit margins, leaving them with no external profits to exchange for dollars to replenish their own currencies. On top of that, the military-civilian dual-use ban aimed at disrupting Japan's national transport is bleak, and expectations of depreciation are high.
Many say the South Korean stock market has been shaken by the U.S. and technology by China. Although this isn't entirely accurate, there is some truth to it.
First of all, the money was indeed taken. With the no-fly ban not yet implemented, the rebound mainly came from foreign capital. Data shows that today marked the largest single-day net buying by foreign capital in history, with SK Hynix at 3.59 trillion and Samsung at 2.10 trillion. After this bottom-fishing, the control of domestic Korean capital may further decline. In contrast, in the previous four trading days (24th-29th), foreign capital had a net sale of 11.95 trillion won. With a swift move, the Korean people were left with a lifetime of massive debt they could never repay, which is truly lamentable.
The technology won't be taken away, but Sanhai's vitality has been severely weakened, and the US has repeatedly required relocation and factory relocations, which objectively contributed time to Chinese capital catching up.
Sanhai's stock price falls, Changxin rises, and the capital cost scissors gap forms between these shifts and gains. The winner of the capital expenditure race essentially depends on who has cheaper capital, and this gap is constantly marking prices to "catch up with time" and shift speed.
The collapse of salaries from the stock price crash + severe damage to morale will accelerate engineers' migration to Chinese capital. The close geographical and cultural ties between China and Korea, combined with China's visa-free policy for South Korea, make it even more convenient—engineers can go to Suzhou or Hefei for interviews without even going through formalities. In reality, the technology leak cases of South Korean prosecutors have never ceased.
From the perspective of the dollar's tide, there are very few countries large enough to absorb enough to cover the U.S. deficit, and the one China definitely won't save is Japan. At least before Changxin conquered HBM, South Korea was still a united front target that pulled and fought simultaneously, so the injuries were probably lighter.
In short, this stock market crash has taken away the right to financing, pricing, major client orders, and the right to claim more and more future profits; What China has taken away is industrial profit margins and technological catch-up time. Japan and South Korea still have factories, engineers, and core technologies, but bear the highest capital expenditures, exchange rate fluctuations, and geopolitical costs. The real reason behind the sharp fluctuations in the Korean stock exchange rate lies here.

As someone who usually follows geopolitics, finance, stocks, and cryptocurrencies, I truly learned and witnessed history in this wave of Hynix ADR listing.
Those with a bit of age might still remember the 1997 Asian financial crisis, when Korean women sold their gold jewelry to support the country.
This Hynix incident also seems like a U.S. design to take up Korea's quality assets.
Everyone is well aware of the current situation of the United States: its overall national strength has declined significantly compared to 1997, and its appetite will only look worse.
While the Korean stock market is fluctuating, the yen exchange rate is also continuously declining. Breaking 165 is only a matter of time, and reaching 180 next year is basically inevitable.
Back to Samsung Hynix, these two typical Korean companies gradually lost equity control through several crises. This crisis is yet another good opportunity to tighten the ropes.
Ignoring the ups and downs, the essence is that the U.S. needs to take off its allies to cover its own losses.
So besides the potential rescue forces mentioned earlier, there may be news of U.S. acquisitions or capital injections coming out. If it really happens, this story will be completely closed. By then, the stock price should have truly started to reverse.
No one knows whether the crisis, currently limited to the storage sector, will spread throughout the entire financial system and the stock market. No one knows whether this "Blue House Agreement" is similar to the "Plaza Accord" that cost Japan thirty years. However, South Korea's political structure means it won't do well—not because it doesn't strive, but because it won't be allowed. $SKHYNIX $SKHY $MU #韩股波动剧烈引监管介入, the finance minister apologized for leveraged ETFs #

On the same day, Japan and South Korea jointly dumped US dollars to support their currencies.
This isn't unusual in itself; I've done it before. What's interesting is the timing and synchronization method. During the New York session, both sides launched simultaneously, with the U.S. side coordinating. This is no longer just simple market intervention; it feels more like a signal—Japan and South Korea are expressing some unease about the credit of the dollar.
This year, the yen has fallen to its lowest level since 1986, and the Korean won has been under pressure. After the predictions were released, the yen rose in a single day, the Korean won rose in a single day, with immediate effects. But intervention is just painkiller and cannot cure the root cause.
What is the root cause of the disease? It is the dollar's credit that is loosening. Global capital is seeking non-sovereign assets as alternative stores of value. The continuous increase in the number of long-term holders of Bitcoin and Ethereum is not without reason.
What crypto traders should really care about is that every time a sovereign currency experiences a crisis of trust, the flow of funds into non-sovereign assets increases by an order of magnitude. While defending their currencies, Japan and South Korea have also accelerated the process of global capital seeking new anchors.
This trend won't end in a day, but every round of exchange rate fluctuations pushes it forward.

#日韩同日抛售美元护汇
Japan and South Korea did something quite rare yesterday—simultaneously selling US dollars and buying their own currencies. Japan directly spent about $52.8 billion, possibly the largest single-day intervention in their history. South Korea has caught up as well, with the won surging to 1418 against the US dollar, a nine-month high.
The Bank of Japan just finished its meeting, keeping interest rates unchanged at 1%. After the meeting, the yen surged sharply from 163.74 to 157.98, but later returned to around 160. The South Korean Deputy Finance Minister made something thought-provoking—"We are maintaining close coordination with the US and Japan, and will continue to cooperate." This is equivalent to indirectly acknowledging the existence of joint intervention.
Even more interestingly, the United States is also cooperating. Reuters captured a notebook from Finance Minister Becent's meeting that read, "Buy 5 to 10 billion yen." The New York Fed then represented the Treasury by selling euros and buying yen. The last time the U.S. did this was during the 2011 Japan earthquake. Jun Mimura hinted that the U.S. was involved, including the prelude to intervention by the "interest rate check."
The motivations of the two countries are quite different. On Japan's side, the yen has fallen to its 40-year low, and import costs can no longer be sustained. On South Korea's side, the won hit a 17-year low last month. But the deeper reason is that U.S. Treasury yields have reached a 19-year high. If the yen falls further, Japan can only keep selling U.S. Treasuries to exchange for dollars to intervene, which in turn pushes U.S. Treasury yields higher and is also detrimental to the U.S.
How long the intervention effect will last is uncertain. Last time during such large-scale operations, the yen lasted a few days before going back. As long as the interest rate differential between Japan and the US remains, the logic of one-sided betting remains intact. However, this time the three countries are acting simultaneously, which is indeed different from before. Speculators who bet on yen depreciation will face much greater resistance than before.
For the crypto market, a weaker dollar usually supports BTC prices. But the joint intervention itself also shows that the global liquidity environment is becoming increasingly contradictory—the U.S. is shrinking its balance sheet while interfering with exchange rates. The long-term impact of this contradictory policy mix on risk assets may be more noteworthy than short-term exchange rate fluctuations.
A rare move in thirty years implemented: the US and Japan join forces to support the yen; the crypto world should not focus only on short-term trading
Many friends in the industry are focused solely on trading contracts at the market's highs and lows, paying no attention to the major news from traditional markets. This time, the US and Japan have joined forces to stabilize the yen, and the impact extends far beyond the forex sector.
The Treasury Minister's checklist during meetings was all recorded, with plans to directly spend $5 to $10 billion to buy yen. The New York Fed sold euros to complete the deal, with Goldman Sachs and JPMorgan Chase involved throughout. Before the move, all major Wall Street banks received the news in advance.
Looking back, the last time the US intervened in the yen was in 2011. Back then, they sold the yen to push prices down, but now they're directly buying in large amounts to support the bottom. It's been nearly thirty years since a joint operation happened, clearly showing that the yen's decline has already reached the official bottom line.
The US dollar index and US Treasury market will fluctuate sharply, and crypto assets, as a risk side, will inevitably be triggered by macro chain reactions.
The market is already tug-of-war between bulls and bears, and with macro variables suddenly increasing holdings, the risks of heavy positions and margin calls are visible to the naked eye. It's essential to tighten your position when operating.
Do you think this major exchange rate intervention will bring a clear downward pressure to BTC?
South Korean Won surges 2% to 1418: Is the crypto market about to see an "East Asian hot money" spillover?
Down 17% in three days, up 14% in one day.
On July 31, the South Korean KOSPI index surged intraday by 14%, marking the largest single-day intraday gain in history. SK Hynix initially soared 28%, Samsung Electronics rose 26%.
The Korea Exchange directly triggered the sidecar mechanism, pausing program trading for 5 minutes.
But that's not the most critical part.
What should really make the crypto market open its eyes wide is another matter—
The Korean Won appreciated 2% against the US dollar to 1418, hitting a nine-month high. The Won hit a 17-year low of 1561.50 last month and has risen over 8% this month, marking the largest monthly gain since March 2009.
What does the Won's appreciation mean?
The Won is a typical "risk-on currency".
When the Won rises, it means global funds are flowing into Asian risk assets. When the Won falls, it means funds are fleeing.
In the past month, the Won rose from 1561 to 1418, an 8% increase. This is not a small fluctuation. It is the result of rare dollar sales intervention by the South Korean foreign exchange authorities combined with joint action from Japan.
Two East Asian export giants simultaneously intervened to stabilize their currencies—the signal is clear: the local currency must not continue to depreciate; funds must be kept domestically.
So the question arises—if funds stay domestic, where do they go?
The "recovery—spillover" script of South Korean retail investors
Samsung Electronics and SK Hynix are the favorite stocks of South Korean retail investors. Down 17% in three days, up 14% in one day—what does this mean?
Those previously trapped have recovered. Those who bottom-fished have profited.
How big is the South Korean crypto market? Won-denominated trading accounts for 30% of the global spot crypto trading volume, second only to the US dollar. South Korea's 52 million population generates about $26 billion in crypto trading volume weekly.
But from early July to July 21, the average daily trading volume of South Korea's top five crypto exchanges was only 597.8 billion Won (about $400 million), down to 1.59% of the Korean stock market trading volume.
Where did the funds go? Into stocks.
Now that stocks have surged and accounts have recovered—where will this liquidity go after being released?
Historical patterns are clear: once South Korean retail investors make money in the stock market, the next step is to rush into the crypto market.
During the KOSPI plunge in the past two weeks, Upbit's trading volume surged by 436%. When the stock market rises, funds flow back into stocks; after making money in stocks, funds spill over into crypto.
The seesaw effect has played out countless times in the South Korean market.
What should you watch most now?
Upbit's Won-Bitcoin/Altcoin trading pair premium index.
As of early July 31, Bitcoin's trading price on Upbit was 91.79 million Won, while the global Binance price was 93.71 million Won, recording a -2.05% "reverse kimchi premium."
Reverse kimchi premium = Koreans selling cheaper than the global market = Korean funds have not returned yet.
Once this number turns from negative to positive, from -2% to +2%, +5%—
That is the first signal that East Asian hot money is starting to spill over into the crypto market.
85% of funds in the Korean market flow into altcoins and newly listed tokens. The return of the kimchi premium means not just Bitcoin will rise—it signals the East Asian version of altcoin season is coming.
You are watching the Fed, the CLARITY Act, and Trump's $1.4 billion crypto income.
But what can really bring you excess liquidity might be a group of recently freed-up South Korean retail investors thousands of miles away in Seoul.
Don't just watch those politicians in Washington.
Watch Upbit's premium closely. That number is more honest than any legislative statement.
$SKHYNIX $SKHY $XSKHY #韩股KOSPI盘中飙升14%,创历史最大单日涨幅
Three days ago, South Korea's KOSPI was still in the ICU hooked up to machines—plunging 17% over three consecutive trading days, intraday dropping over 12%, triggering circuit breakers repeatedly.
And today?
KOSPI closed with a surge of 17.91%, marking the largest single-day gain since data has been recorded in 1980. SK Hynix hit the daily limit up, rising 30%, a historic first. Samsung Electronics rose 26.81%, with its market cap returning to $1.2 trillion.
Down 17% in three days, up 18% in one day.
This isn’t a candlestick chart; it’s bungee jumping.
Who directed this drama?
Three forces slammed in simultaneously:
First, the U.S. stock market set the pace. Overnight, the Nasdaq surged 2.78%, the Philadelphia Semiconductor Index soared over 8%, SanDisk rose 26%, Micron climbed over 18%. Microsoft's single-day market cap jumped by $450 billion, setting a record for single-stock daily market cap increase. AI trading returned overnight.
Second, the big players personally stepped in. SK Group Chairman Chey Tae-won bought 3,620 shares of SK Hynix in his own name during the plunge, worth about 4.8 billion KRW. This was Chey Tae-won's first direct holding of SK Hynix shares; previously, he only held them indirectly through the holding company. If even the chairman is bottom-fishing personally, won’t retail investors rush in?
Third, the central bank intervened. South Korea’s foreign exchange authorities made a rare sale of dollars to intervene, causing the won to appreciate 2% to 1418, a nine-month high. The market even suspects a joint intervention by Japan and South Korea in the forex market. Simply put: the national team stepped in.
The combination of these three forces resulted in today’s towering bullish candlestick.
But what truly turned this rally into a "long-short double explosion" was the hidden factor: leverage.
On May 27, South Korea launched "single-stock leveraged ETFs"—allowing retail investors to take 2x leveraged bets on specific stocks.
The result?
Retail investors net bought as much as 140 trillion KRW (about $9.7 billion), far exceeding foreign institutional investors. The leveraged ETF asset size exploded from less than $10 billion at the start of the year to over $50 billion by June.
Then the market turned downward.
The 2x leveraged ETF tracking SK Hynix has lost over 80% since its June peak; similar products for Samsung Electronics have retraced nearly 75%. More than 1.2 million leveraged retail accounts received margin calls, and between 320,000 to 360,000 accounts were completely liquidated.
A 17% drop in three days was essentially a collective liquidation of leveraged longs.
Today’s 18% rise was a targeted short squeeze using forex intervention and the chairman’s bottom-fishing news—shorts were crushed.
Three days ago, the longs exploded; today, the shorts exploded.
Isn’t this the "long-short double explosion" most familiar in the crypto world?
What’s the most ironic?
On July 29, South Korean Finance Minister Ju Yeong-cheol publicly apologized in the National Assembly—admitting the government "launched single-stock leveraged ETFs without careful consideration."
They didn’t think it through when launching, and apologized after the liquidations.
The chairman of the Financial Services Commission, Lee Ik-yeon, said they are considering restricting such products to "professional investors."
But will it help?
JPMorgan data shows leveraged ETF assets plunged from $50 billion to $16 billion, a nearly 70% drop.
The blood of 700,000 retail investors has already been drained.
To be blunt:
This "painting the gate" episode of South Korea’s KOSPI essentially transplanted the brutality of crypto contracts fully into the traditional market.
Down 17% in three days, up 18% in one day. This isn’t value investing; it’s a violent liquidity backlash. This isn’t driven by fundamentals; it’s a retaliatory rebound after leveraged liquidations.
What’s even scarier—South Korea has a central bank backstop, forex intervention, and a finance minister’s apology.
When your altcoin liquidates, who will back you up?
Who will sell dollars for you? Who will apologize to you?
$SKHYNIX $SKHY $SAMSUNG #韩股KOSPI盘中飙升14%,创历史最大单日涨幅
If the global market crashes next week, $BTC and $ETH will be the first to be drained
If you have BTC and ETH in your position, next week the most important focus is not on candlesticks, but on Japan.
This situation may be spreading faster than you think—Japan is selling US Treasuries→ US Treasury yields are surging→ global risk asset valuations are under pressure→ crypto is bleeding first. This chain is already in motion, and next week is the trigger point.
Why is crypto at the center of the storm?
The logic is simple: BTC and ETH do not generate cash flow; their prices are supported entirely by liquidity expectations. When global liquidity tightens, interest-bearing assets can still hold up on yields, but crypto survives from head to toe on the "next buyer offering a higher price"—when a wave of risk aversion hits, crypto is always the first to be thrown away and the last to be picked up.
The current state is already fragile. BTC has been stuck in the 62,000-64,000 range for two months, with the center of gravity slowly shifting downward, and ETH repeatedly struggling between 1,820 and 1,900. Above is a trapped market, below is a faint 60,000 mark. If the global market were to be drained again, BTC and ETH would have no safety cushion at all.
And the syringe for the blood draw, Japan already holds it.
This round of Japanese operations is the largest "dumping" in history
What happened in the past few days? Let's sort out the timeline:
July 30: Japan's Ministry of Finance spent 8.45 trillion yen (about $53 billion) in a single day to buy yen, setting a new record for Japan's single-day intervention. Within an hour, the USD/JPY plunged from 163 to 157.96.
July 31: Japan intervenes for the second consecutive day; The New York Fed, representing the Treasury, stepped in, selling euros and buying yen — the first joint intervention between the US and Japan in nearly 30 years.
As of now: Japan has consumed about $130 billion in foreign exchange reserves. The note from Besent, which reads "Buy 5 to 10 billion yen," was photographed and circulated worldwide—even the United States had to intervene.
Why does the US personally rescue the yen? Because the majority of Japan's foreign exchange reserves are U.S. Treasury bonds. This $130 billion consumption is essentially selling U.S. Treasuries to buy liquidity.
What is the problem? The problem is that the yen simply cannot be saved. The root cause of yen depreciation is the US-Japan interest rate gap (Japan 1.0% vs. US 3.5-3.75%). As long as carry trades persist, the yen remains under pressure, and intervention can only create a pulse rebound. After every historical intervention, the yen continued to depreciate, and Japan's foreign exchange weakened more and more.
How does the chain transfer to encryption?
Japan continues to intervene → deplete U.S. Treasury reserves→ U.S. Treasuries are being continuously sold off→ forcing U.S. Treasury yields higher.
The 30-year Treasury yield is now above 5.2%, the highest since 2007. If Japan were to sell off on a large scale, this number would be even higher. What does rising U.S. Treasury yields mean? This means risk-free returns have increased, and money worldwide would prefer to lie on US Treasuries and live off interest rather than gamble on risky assets.
This is the distance from Japan to BTC—not geopolitical conflict, not war, but pure contraction of the capital chain. When U.S. Treasury yields hit new highs, BTC's appeal diminishes, capital outflows accelerate, and rebounds are suppressed.
Next week, Japanese Finance Minister Katayama Satsuki will officially announce the US-Japan joint action on Monday (August 3), and intervention is expected to continue to intensify. Each increase in holdings marks a new round of Treasury sell-offs and a new round of bleeding in the crypto market.
Keep a close eye on three signals
US Treasury yield: If the 30-year yield breaks above 5.2%, it would be a direct signal of tightening liquidity, leaving crypto with no chance to run.
USD/JPY: After intervention, it briefly rebounded to 157, but has now fallen back to around 160. If it approaches 163 again, Japan will definitely continue to intervene, and US debt pressure will increase simultaneously.
BTC 60,000 Level: Global volatility is transmitted to crypto, and BTC's 60,000 is the last psychological defense. If it can't hold on, a new round of panic selling begins.
Next week's risk is not about "whether it will come," but "it has already arrived, but the market hasn't fully priced in yet."
