Good Morning Blocksignal Community,
Bitcoin gave back most of this week's rally on Thursday, sliding from a local high near $87,500 to briefly touch $82,900 before settling in the low $83,000s, as a hotter-than-expected PMI print pushed traders to price in four separate Fed rate hikes by mid-2027 and sent the 10-year Treasury yield to its highest level since 2007. Bitget also disclosed a hack across its hot and warm wallets, though the exchange's own loss estimate and what's been independently confirmed on-chain don't yet match up. Underneath both headlines, the more interesting story held: bitcoin's correlation with the surging yields that supposedly drove the sell-off is close to zero over any meaningful timeframe, spot ETF inflows kept climbing regardless of the price pullback, and JPMorgan flagged that bitcoin now trades above miners' estimated production cost for the first time in 280 days.
Rate Hikes Repricing, Not a Crypto-Specific Selloff
The preliminary US September PMI came in at 58.4, the fastest pace of expansion since 2021, and markets responded by moving the goalposts on the Fed. CME FedWatch data cited by CoinDesk showed traders pricing in four separate quarter-point hikes by June 2027, which would take the federal funds rate to a 4.75%–5% range. Estimates of the immediate probability varied by outlet and by the hour: KuCoin put the odds of an October hike at 69.7%, Yahoo Finance's later read had it at 75.3%. Either way, the reaction in rates was unambiguous — the 10-year Treasury yield jumped to roughly 5.13%, its highest since 2007, the MOVE index (a gauge of Treasury-market volatility) surged 21% to 95, and the dollar index pushed above 101, up 3% year-to-date. Gold, usually a rates-sensitive asset like bitcoin, sat roughly 25% below its January highs. Equities took the same hit, with the Nasdaq down 1.13% and the S&P 500 off 0.75% on the day — this was a broad repricing of the rate path, not something specific to crypto.
That's worth separating from the "bitcoin can't handle higher yields" narrative that tends to accompany days like this. A CoinDesk analysis published the same day ran the numbers: bitcoin's 90-day correlation with the 10-year yield sits at -0.18, the 180-day figure is -0.06, and the one-year correlation is essentially flat at -0.03. Bitcoin is up 191% since 2021 despite yields climbing more than 400 basis points across several countries over that stretch. Lacie Zhang, research lead at Bitget Wallet, framed the near-zero correlation as "a genuine portfolio advantage" because it suggests bitcoin isn't simply trading as a duration or rates asset. None of that means a single volatile day in the bond market can't jolt crypto prices short-term — Thursday is a clean example of that — but the multi-year relationship is closer to noise than a real driver, and today's pullback doesn't change that pattern.
Bitget's Numbers Don't Line Up Yet
Bitget confirmed a security incident affecting its hot and warm wallet layers, with CEO Gracy Chen describing "unauthorized transfers from some of our hot wallets." The exchange put total exposed assets at $351.6 million, paused withdrawals while it investigates, and pointed to a user-protection fund north of $464 million as a backstop; Chen said cold wallets remain fully secure and that the breach was contained to a portion of the hot and warm tiers. Independent on-chain analysts, including Arkham Intelligence, had flagged unusual wallet movement before Bitget's own announcement, and separately tracked roughly $170 million moving from several Bitget-labeled wallets — a mix of ether, USDT, USDC, AVAX and BNB — to a single new address within about an hour, with that address already swapping the funds through decentralized exchanges. As of the reporting, it isn't confirmed whether that $170 million transfer is the breach itself, a partial slice of the larger $351.6 million figure, or an unrelated internal Bitget operation — the two numbers haven't been reconciled publicly. Worth watching for an official incident report before treating either figure as final.
Miners Cross a Cost Floor, ETFs Keep Buying
JPMorgan analysts, led by Nikolaos Panigirtzoglou, noted that bitcoin's move to roughly $84,100 puts it back above its estimated $85,000 production cost for the first time after 280 days spent below that threshold — a stretch comparable to the roughly 224-day span bitcoin spent below cost in 2018. The bank argued that a sustained move above production cost would ease the risk of forced selling by miners, who have already adjusted over the past several months by relocating to cheaper power, retiring older machines, and increasingly shifting capacity toward AI hosting contracts that pay more predictably per megawatt than mining does. JPMorgan framed that migration as a structural positive for bitcoin, since it caps hash rate growth (down about 19% from October's peak, with difficulty off roughly 15%) rather than adding to it. Separately, bitcoin reclaimed its 365-day moving average on September 22 for the first time in 310 days, a level some traders watch because bitcoin has historically traded higher a year later in each of the five prior instances this happened — though two of those five setups (2018 and 2022) failed within 90 days with drawdowns of 27% and 59% respectively, so it's a pattern with real exceptions, not a rule. On flows, spot bitcoin ETFs took in $191 million net on September 24, a sixth consecutive day of inflows, while spot ether ETFs added $66 million, their fifth straight positive day — demand that, so far, hasn't flinched at the day's price pullback.
Today's Watch
Friday brings August durable goods data and the revised University of Michigan consumer sentiment index, both at 8:30am and 10am ET respectively — the preliminary sentiment reading had already dropped to 47.8, with year-ahead inflation expectations at 4.6%, so a further downside surprise could reinforce today's rate-hike repricing rather than calm it. Fed speakers John Williams and Beth Hammack are also scheduled to appear. None of this is a reason to change position size ahead of the data — know where your liquidation levels sit if you're using any leverage into a day with this many rate-sensitive releases stacked up.
