Why the Fed’s expanded balance sheet isn’t QE for Bitcoin

The Federal Reserve raised the federal-funds target range to 3.75%–4.00% on Sept. 16 and left in place an ample-reserves operating system. The implementation directive set the interest rate paid on reserve balances at 3.90% effective Sept. 17 and retained the New York Fed’s authority to buy Treasury bills and Treasuries with up to three years remaining to maintain reserve levels.

Officials distinguish between large-scale asset purchases that target longer-term interest rates and reserve-management purchases that add short-term liquidity. Vice Chair Philip Jefferson described quantitative easing as a tool that removes duration risk from private portfolios, while reserve-management purchases are intended to preserve ample reserves and support control of overnight rates. New York Fed markets chief Roberto Perli noted recent reserve-management operations have been limited to Treasury bills and contrasted those with longer-duration purchases used to lower longer-term rates.

The Fed’s reserve-management framework began in December 2025 and is not on a preset path. The operations schedule for Sept. 15–Oct. 14 lists net reserve-management purchases at zero and shows about $15.6 billion of Treasury-bill purchases funded by principal payments from agency securities, a reinvestment flow separate from net reserve-management buying. The trading desk retains the capacity to add short Treasuries but has not used that capacity for net reserve-management operations in the current schedule.

Accounting through July 1 shows the System Open Market Account bought nearly $250 billion of Treasury bills since early January, with roughly $160 billion attributed to reserve-management purchases and about $90 billion from agency-security reinvestments. Over the same comparison period, total Fed assets rose by $151 billion and reserve balances increased by $54 billion as other balance-sheet items shifted. The H.4.1 release reported total assets of $6.740619 trillion on Sept. 9, up $3.415 billion from the prior week and $134.657 billion from a year earlier.

Money-market rates ahead of the Sept. 16 decision were close to administered rates: on Sept. 15 the secured overnight financing rate was 3.64% and the effective federal-funds rate was 3.63%, near the then-current interest rate on reserve balances of 3.65%. Overnight reverse-repo take-up was about $0.7 billion on Sept. 15.

Cryptocurrency markets showed limited movement around the announcement. Bitcoin traded near $76,000 and U.S. spot Bitcoin exchange-traded funds recorded $450.4 million of net outflows on Sept. 15.

Future changes in the Fed’s balance sheet can be described by program purpose, scale and the maturity composition of securities purchased. Observers will look for announced net reserve-management purchases on the Fed’s schedule and whether purchases include longer-duration assets that affect longer-term borrowing costs.
