The Federal Reserve raised its benchmark federal-funds target range by 25 basis points to 3.75%–4.00% on September 16, 2026, the first rate hike since 2023, pairing the widely expected move with projections that signal restrictive policy may persist. Bitcoin traded narrowly between $75,000 and $75,800 around the decision, but analysts warned that the more important development was the central bank’s forward guidance.
The FOMC vote was unanimous, and officials cited elevated inflation and resilient domestic spending. The September Summary of Economic Projections showed 12 participants projecting a 2026 year-end federal-funds midpoint of 4.125%, four projecting 4.375%, and only two projecting 3.875%. Median 2026 core PCE inflation was projected at 3.4%, well above the Fed’s 2% target, while median 2026 real GDP growth rose to 2.3% from 2.2% in June. Administered rates were set with interest on reserve balances at 3.90%, the standing repo rate at 4.00%, and the reverse-repo offering rate at 3.75%.
The macro backdrop was further clouded by Treasury International Capital data for July 2026. Foreign private investors bought $45 billion of Treasury bills but sold $29.1 billion of longer-dated Treasury notes and bonds. Although official foreign institutions bought $25.5 billion of notes and bonds, the combined long-duration flow was slightly negative, and net foreign acquisition of all long-term securities was negative $27.9 billion. The 10-year Treasury yield rose from 4.48% to 4.75% during July, while the 30-year climbed from 4.97% to 5.27%. By September 16, the curve showed 3.96% at one month and 5.01% at 10 years.
For Bitcoin, the transmission runs through financial conditions: higher risk-free returns raise the opportunity cost of holding a non-yielding asset, while tighter credit can reduce capital available for risk assets. Coinbase Institutional previously noted that 10-year real yields near 2.4% had reduced the incentive to allocate capital to crypto. The Block cited an analyst saying Bitcoin had moved roughly four times as much as the S&P 500 over the prior two FOMC trading days, suggesting crypto remains acutely sensitive to macro surprises even when individual decisions are priced in.
Ether also swung after the decision, though the immediate crypto reaction was contained. The broader concern is that a higher-for-longer rate environment, persistent inflation above target, and private foreign selling of long-dated bonds could keep liquidity and funding conditions tight, making a sustained Bitcoin rally harder to justify until long-term yields decline and private accounts return to Treasury notes and bonds.
