Bitcoin Enters September Near $79,000: Warsh's Hawkish Turn, 58% Hike Odds, and Whether the Worst Month Curse Holds

Bitcoin (BTC) trades near $79,000 heading into September after Fed Chair Kevin Warsh's hawkish first Jackson Hole keynote knocked it from a peak of $81,238 to about $77,800, triggering roughly $468 million in crypto liquidations, $351 million of them longs.

Warsh called the 2% inflation target firm and fixed, said summer inflation data had not shown underlying trends meaningfully improving, warned that "sustained policy restraint" may be required, and declared the era of routine forward guidance over.

Markets repriced fast: implied odds of a rate hike at the September 15 to 16 FOMC meeting jumped to roughly 58% from about 35%, with July PCE inflation running 3.7% and core at 3.3%.

September is historically Bitcoin's weakest month, with a median return near negative 4.5% over the past decade and six straight red Septembers from 2017 to 2022, but the month closed green in 2023, 2024 and 2025, and Bitcoin just posted its best August since 2017.

Support sits at $76,800 to $77,000 with $73,700 to $75,200 below; resistance is $79,500 to $80,300 and then the $81,000 to $81,500 highs. The calendar stacks jobs data on September 4, CPI on the 11th, the Senate's return to the CLARITY Act on the 14th and the Fed decision on the 16th.

 

 

Kevin Warsh's first Jackson Hole keynote on Friday, August 28 was the speech the crypto market had feared. The Fed Chair described the 2% inflation target as firm and fixed, said the better than expected summer CPI and PCE prints had not demonstrated that underlying inflation had meaningfully improved, and noted that progress since the 2022 highs has been modest for two years. With business investment growing around 9%, the S&P 500 up roughly 20%, unemployment near 4% and credit conditions easy, he argued the economy gives the central bank no reason to tolerate elevated prices. Getting inflation back to target, he said, may require "sustained policy restraint," adding that the Fed must be confident prices are moving toward the goal clearly and quickly enough, or it has work to do.

Two further messages mattered as much as the tone. Warsh drew a line between the Fed's mandate and the Treasury's desire to lower borrowing costs through its expanded bond buybacks, dashing hopes of coordination that had helped power August's rally. And he declared that forward guidance as a routine habit had overstayed its welcome, which means the coming data releases, not the next speech, will set expectations. Warsh did not commit to any specific decision.

 

The reaction was textbook risk off. Treasury yields rose, the dollar strengthened, and Bitcoin, which had already slipped 4.1% from its $81,238 peak as leverage built into the event, fell about 3% more to roughly $77,800 after the speech. Around $468 million in leveraged crypto positions were liquidated over the day, roughly $351 million of them longs, with more than $200 million wiped out in a single hour. Ethereum fell toward $2,420 and XRP to about $1.36. The selloff came hours after $6.36 billion in Bitcoin options expired on Deribit, clearing a large block of contracts just before the market had to reprice. Bitcoin futures open interest dropped about 4.5% from its peak, a healthy leverage flush that partially reset an overbought tape.

Rate expectations moved the most. Implied odds of a hike at the September 15 to 16 meeting jumped to roughly 58% from about 35% before the speech, according to market pricing tracked by several desks, though estimates vary by venue. July PCE inflation of 3.7% with core at 3.3% gives the hawks cover. Bitcoin's own 2026 record around Fed meetings is unkind: three of five decision days this year produced bearish pivots, with liquidations of $300 million to $500 million on each.

 

Calendar effects add to the caution. September has historically been Bitcoin's weakest month, with a ten year mean return of about negative 2.6% and a median near negative 4.5%, including six consecutive red Septembers from 2017 through 2022 and a worst case of negative 13.9% in 2019. Stocks share the pattern: the S&P 500 has averaged roughly negative 0.7% in September since 1950, finishing higher only about 44% of the time. The counterargument is that the curse has been weakening. Bitcoin closed September green in 2023, 2024 and 2025, and the fourth quarter that follows is historically its strongest stretch of the year.

The structural backdrop is also stronger than in past Septembers. Bitcoin enters the month after its best August since 2017, up more than 20%, and US spot Bitcoin ETFs recorded nine consecutive sessions of inflows through August 27, including $242 million that day, a persistent institutional bid that did not exist during the six year losing streak. The Coinbase premium has recovered to neutral after two weeks in negative territory, though neutral is not the same as strong. Funding rates rose sharply after the speech as bulls kept paying to hold longs, a sign of conviction that cuts both ways if the tape turns.

 

Technically, Bitcoin is holding the first line that matters. Immediate support sits at $76,800 to $77,000, the zone that caught Friday's selling; losing it would open a test of $73,700 to $75,200. Overhead, $79,500 to $80,300 is the resistance the market lost after the speech, and the $81,000 to $81,500 peak zone above it is the gateway to new cycle highs. Daily momentum indicators remain elevated, so consolidation between $77,000 and $80,000 into the Fed decision is the base case many analysts describe.

The calendar is dense. The August jobs report lands on September 4, CPI on September 11, the Senate returns on September 14 with the CLARITY Act back on its docket, and the FOMC decides on September 16. Each of those prints can reset the 58% hike odds in either direction, which is precisely what Warsh intended when he retired forward guidance.

 

September opens with a clear map and a hostile calendar. Traders can follow the live BTC/USDT price on MEXC, set alerts at $77,000 and $80,300, watch ETH/USDT and XRP for the higher beta reaction to each data print, and use stop loss and take profit orders on MEXC Futures to predefine risk around the four dated catalysts rather than reacting mid move. With leverage rebuilding and a Fed that has explicitly told markets to trade the data, position sizing matters more than usual.
