December FOMC minutes show why the Fed thinks calm markets can still turn volatile

The minutes from the Federal Reserve’s December 2025 policy meeting show officials paying close attention to a risk that rarely drives headlines but can rattle markets quickly: whether the financial system could quietly run short of cash even if interest rates barely move.

Released on Dec. 30, the minutes from the Dec. 9–10 Federal Open Market Committee meeting suggest policymakers were broadly comfortable with the economic backdrop. Investors, the minutes note, largely expected a quarter-point rate cut at that meeting and anticipated additional reductions in 2026, and rate expectations changed little over the intermeeting period.

But the discussion extended well beyond the policy rate. The minutes repeatedly highlight signs that short-term funding markets — where banks and financial firms borrow and lend cash overnight to facilitate daily transactions — were becoming tighter.

At the center of that concern is the level of cash, known as reserves, in the banking system. The minutes say reserves had fallen to what the Fed considers “ample” levels. While that sounds reassuring, officials described this zone as one where conditions can become more sensitive: small swings in demand can push overnight borrowing costs higher and strain liquidity.

Several warning signs were flagged. The minutes cite elevated and volatile overnight repo rates, rising gaps between market rates and the Fed’s administered rates and increased reliance on the Fed’s standing repo operations.

Several participants noted that some of these pressures appeared to be building more rapidly than during the Fed’s 2017–19 balance-sheet runoff, a comparison that highlights how quickly funding conditions can deteriorate.

Seasonal factors added to the concern. Staff projections indicated that end-of-year pressures, late-January shifts, and especially a large springtime influx tied to tax payments flowing into the Treasury’s account at the Fed could sharply drain reserves. Without action, the minutes suggest, reserves could fall below comfortable levels, thereby increasing the risk of disruption in overnight markets.

To address that risk, participants discussed initiating purchases of short-term Treasury securities to maintain ample reserves over time. The minutes emphasize these purchases are intended to support interest-rate control and smooth market functioning, not to change the stance of monetary policy. Survey respondents cited in the minutes expected purchases to total about $220 billion over the first year.

The minutes also show officials seeking to enhance the effectiveness of the Fed’s standing repo facility — a backstop designed to provide liquidity during periods of stress. Participants discussed removing the tool’s overall usage cap and clarifying communications so market participants view it as a normal part of the Fed’s operating framework rather than a last-resort signal.

Markets are now focused on the next policy decision. The federal funds target range currently stands at 3.50% to 3.75%, and the next FOMC meeting is scheduled for Jan. 27–28, 2026. As of Jan. 1, CME Group’s FedWatch tool showed traders assigning an 85.1% probability to the Fed holding rates steady, versus a 14.9% chance of a quarter-point cut to a 3.25%–3.50% range.
