On September 17, the Federal Reserve announced a 25 basis point rate hike, raising the interest rate to 3.75%-4.00%.
The vote was unanimous with 12 in favor. The dot plot indicates one more rate hike within the year. The 10-year US Treasury yield hovered near 5%, the highest since 2007. On the same day, the Bank of Japan raised its interest rate to a 31-year high.
According to traditional logic, in such a macro environment, BTC should have fallen.
It rose.
On September 18, BTC surged past $81,000 intraday, with a single-day increase of about 6%, marking the first time in 11 days it reclaimed $80,000. Within one hour, $183 million in short positions were liquidated, with 95 cents of every dollar liquidated coming from those betting on a decline.
Traders who bet on "rate hikes → BTC crash" over the past week were buried by the market.
What happened?
First layer: The rate hike itself is the biggest positive.
CME FedWatch showed the market had already priced in over a 93% probability before the hike.
Before the boot dropped, everyone was fearful. After it dropped, uncertainty vanished.
Fear was fully priced in, leaving only relief.
But that’s not all.
Second layer: The shorts were too crowded and ended up squeezing themselves out.
Before the rate hike, BTC had been steadily declining from late August to around $75,000. The Senate rejection of the CLARITY Act, the Fed’s hawkish stance, and the Bank of Japan’s tightening — a triple hit that boosted short sellers’ confidence.
CoinGlass data showed that between $76,000 and $83,600, there was a cumulative $4.79 billion in short liquidation pressure, more than twice the long liquidation below.
Everyone thought BTC was doomed.
But on the day of the Fed rate hike, BTC didn’t crash. Nor did it crash the next day.
Shorts started to panic. Before the weekend, profit-taking, stop-loss covering, and forced liquidations — a single bullish candle swept all leveraged shorts away.
FxPro’s chief analyst Kuptsikevich put it bluntly: "This is a position adjustment, not a fundamental-driven move."
Third layer: The real catalyst was hidden in Powell’s words.
At the post-rate hike press conference, Fed Chair Powell said:
"I don’t do forward guidance."
In plain language, that means: I won’t tell you whether or how many more hikes are coming.
But the dot plot leaked the bottom line — among 18 participants, 12 expect one more hike this year, 4 expect two. By the end of 2027, the median policy rate is expected to be 4.1%. This means the entire tightening cycle has only one or two moves left.
Goldman Sachs adjusted its baseline scenario to two hikes that afternoon. But the market read the signal completely differently —
not "the rate hike cycle is starting," but "the rate hike cycle is ending soon."
BTC priced in the latter.
But don’t celebrate too soon. CoinShares poured cold water.
Research head James Butterfill released a report on the day of the hike titled: "A tough situation before year-end."
Two core logics:
First, a hawkish Fed. The dot plot removed rate cut expectations before 2027, which is more fatal than the hike itself. A stronger dollar and tighter liquidity drain the "water level" BTC depends on most.
Second, Iran conflict pushing energy prices up, inflation pressure remains, increasing the probability of more hikes this year.
Butterfill’s exact words: "Without substantial improvement in inflation outlook or significant change in monetary policy expectations, a decisive BTC breakthrough above $80,000 is unlikely."
So why did BTC still rise?
Because the market is betting on a scenario CoinShares didn’t explicitly state but is logically sound:
If political uncertainty continues to rise and long-term yields keep climbing, the Fed will eventually be forced to take more aggressive policy action.
In other words: it’s not that the macro environment improved, but the market is pre-pricing that "macro will get so bad that easing becomes inevitable."
BTC’s independent rally is not a victory over tightening but a bet on future easing.
Technicals also support this narrative.
Galaxy Research head Alex Thorn pointed out that BTC has already risen above the 50-week moving average. Historically, BTC has reclaimed this line three times in four bear markets, usually signaling a phase bottom formation. "The current rally looks genuine."
But don’t overlook one detail: the 365-day moving average is at $81,700, and since June, BTC has never closed above this line.
$82,000 is the next battleground.
Simply put, the keyword for this rally is: short covering.
ETF fund flows also tell the story. On September 15, spot Bitcoin ETFs saw a net outflow of $450 million, the largest in three months. Two days later, $159 million flowed back in. Meanwhile, Ethereum ETFs continued bleeding, XRP funds kept outflowing, with only BTC and ZEC attracting capital.
Funds aren’t returning to crypto; they’re seeking the most resilient assets to hide in.
This is defense, not offense.
So why is BTC defying the rate hike cycle?
Because the rate hike itself is positive, because shorts are too crowded, because Powell refuses to give forward guidance, forcing the market to rely on bets.
But the fundamental reason is: the market doesn’t believe this tightening cycle will last.
From the moment the 10-year Treasury yield hit 5.041%, the market has been betting that high rates will first break something, then the Fed will have to turn around.
BTC is betting on that "must-turn-around" moment.
While others fear rate hikes, BTC fears the Fed won’t admit defeat fast enough.
