There is a distinction the Federal Reserve really wants you to understand: managing the size of its balance sheet is not the same thing as changing banking regulations. John C. Williams, President of the Federal Reserve Bank of New York, has been making this case explicitly, and the timing matters.

Williams has argued that reserve management purchases, the technical operations the Fed uses to keep liquidity flowing smoothly, should not be read as signals of broader monetary policy shifts, and certainly should not be conflated with regulatory reform. In other words, when the Fed buys assets to maintain adequate reserves, it is doing plumbing work, not rewriting the rulebook.

What Williams is actually saying

The Fed operates under what it calls an “ample reserves” framework, where enough reserves are kept in the banking system so that short-term interest rates stay stable, without the Fed having to intervene constantly.

Post-2008 liquidity regulations, particularly the Liquidity Coverage Ratio introduced after the Global Financial Crisis, significantly increased how many reserves banks structurally need to hold. The rules written after the last crisis made banks want to keep more cash on hand, which means the Fed’s balance sheet has to be larger just to keep the system functioning normally.

Williams is drawing a direct line here. The balance sheet got bigger because regulations demanded more reserves. That is a technical consequence. It should not, he argues, become a justification for walking back those regulations, or for treating balance sheet operations as a backdoor form of regulatory relief.

The Fed’s balance sheet stood at approximately 21.6% of GDP as of mid-2026, a figure that reflects the structural reality of a post-crisis financial system, not an active stimulus posture.

The FOMC’s recent moves

The Federal Open Market Committee halted its balance sheet reduction program in December 2025, determining that reserve levels had reached the “ample” threshold the framework targets.

With the reduction paused, the FOMC is now weighing gradual asset purchases to address ongoing liquidity needs as they arise. Williams has been careful to frame these potential purchases as reserve management operations meant to be invisible to monetary policy signals. The Fed does not want markets reading a routine reserve add as a pivot toward easier financial conditions.

Economist Stephen Miran has been among the critics pushing back on this framing, arguing that the Fed’s balance sheet size is increasingly being dictated by liquidity regulations, which raises a legitimate question about the direction of causality: are regulations driving the balance sheet, or should the balance sheet drive a rethink of the regulations? Williams is firmly in the former camp.

Why crypto and risk asset markets should pay attention

Williams has flagged that reserve demand dynamics are nonlinear and uncertain, which is the Fed’s way of saying they do not fully know where the floor is. Investors should watch for any signals around the timing and pace of the gradual asset purchases the FOMC is now considering, as that uncertainty cuts both ways.

The regulatory separation argument also has a longer-term implication. If the Fed holds firm that balance sheet policy and regulatory policy are distinct, then any future push to loosen post-GFC liquidity rules would have to happen through the normal regulatory process, not as a side effect of balance sheet normalization.
