Why the Fed's Ample Reserves Framework Makes Curbing Idle Funds Nearly Impossible

The idea sounds appealing: redirect capital that merely circulates within the financial system back into the real economy. A recent viewpoint circulating in policy circles suggests that two-thirds of new US currency supply simply moves between financial institutions rather than fueling productive investment. The proposed solution? Tighten the screw on commercial banks by eliminating interest payments on excess reserves—or even imposing fees—to force lending into the actual economy. Meanwhile, defensive stocks like Coca-Cola and Walmart have rallied on expectations of this shift. This narrative echoes principles from China’s 2017 National Financial Work Conference, which similarly emphasized channeling capital into the real economy rather than letting it idle within the banking system.

But here’s the critical flaw in this thinking: the Fed’s current operational framework makes such a policy virtually impossible to execute without triggering financial turmoil.

The Liquidity Paradox: Why Forced Deleveraging Backfires

The challenge lies in what economists call the “liquidity trap.” When natural interest rates fall to historically low levels, both businesses and investors lack attractive investment opportunities outside the financial system. Capital doesn’t naturally migrate to the real economy—it stays trapped within banking channels, accumulating leverage in the process.

Now consider what happens if policymakers try to forcibly redirect this capital. On the surface, it seems simple: if banks hold excess reserves, just penalize them until they lend. But this overlooks a crucial reality: nearly all capital currently in the banking system is already deployed. It’s not sitting idle—it’s embedded in financial positions, collateral chains, and leverage structures.

Withdrawing liquidity from this tightly wound system would be like removing load-bearing bricks from a completed skyscraper. Financial institutions desperate for cash would immediately dump securities, unwind positions, and liquidate collateral. Money market rates would spike instantly. Rather than achieving the goal of stimulating real-economy lending, this forced deleveraging would likely trigger a funding crisis similar to what nearly broke the system in mid-March 2020.

How Ample Reserves Become Structural Leverage

The Federal Reserve operates under what’s formally called the “ample reserves framework”—a deliberate operational approach established after years of crisis experience. This isn’t simply a preference; it’s a recognition that modern financial systems require sufficient liquidity buffers to function.

When reserves are constrained, financial institutions compete aggressively for available liquidity. Someone loses access to cash, leverage collapses rapidly, and contagion spreads. The framework exists precisely to prevent this cascade.

Attempting to shrink ample reserves while natural interest rates remain depressed would pit two forces in direct conflict: the need to maintain system stability versus the desire to force capital reallocation. In any such conflict, stability wins. The system will protect itself through credit events, forced selling, and ultimately, emergency central bank interventions.

Historical Precedent: The QE Cycle Nobody Can Escape

The historical record makes the policy trap abundantly clear. When the Bank of Japan confronted its own secular stagnation, it began quantitative easing in March 2001. The Federal Reserve followed: QE1 launched November 25, 2008, followed by QE2 (November 3, 2010), QE3 (September 2012), and QE4 (December 2012). Then came March 15, 2020, with a $700 billion injection, followed by unlimited QE on March 23, 2020.

Notice the pattern: each crisis forced more easing, not less. This wasn’t policy failure—it was monetary physics under conditions of persistently low natural rates. The Fed didn’t choose to keep expanding ample reserves; structural conditions demanded it.

According to Federal Reserve board member Stephen I. Miran, projections suggest the US neutral interest rate will decline significantly in coming years. If accurate, this forecast all but guarantees the Fed will be unable to shrink the ample reserves framework. The policy simply cannot succeed when the underlying economic conditions that justified its creation are intensifying.

The Path of Least Resistance

Walsh’s ambitions to curb idle fund circulation and compress the Fed’s balance sheet both confront the same fundamental constraint: they require fighting against the structural forces that created the current monetary system design. Only rate cuts—the easiest policy tool to deploy—remain genuinely within reach.

Shrinking ample reserves? That’s fighting gravity. History suggests it won’t end well.
