Warsh advocates for a nuanced Fed policy: simultaneously cutting interest rates while passively shrinking the balance sheet by letting bonds mature. This "passive quantitative tightening" aims to reduce the Fed's market footprint without the shock of active selling, representing a middle ground between aggressive easing and hawkish tightening.

Former Dallas Fed President Robert Kaplan suggests that while rate-setting policy will remain independent, a new Fed Chair could significantly alter balance sheet management. He anticipates a renewed debate about extending the portfolio's average maturity by buying more long-term bonds.

The post-Powell Fed is likely to reverse the QE playbook. The strategy will involve aggressive rate cuts to lower the cost of capital, combined with deregulation (like SLR exemptions) to incentivize commercial banks to take over money creation. This marks a fundamental shift from central bank-led liquidity to private sector-led credit expansion.

Recent increases in funding market spreads suggest banking reserves may be too restrictive. This puts pressure on the Federal Reserve to end its balance sheet runoff (QT) sooner than its official timeline, creating a potential for market disappointment if the Fed delays its decision.

J.P. Morgan believes the Fed's balance sheet runoff can continue until at least Q1 2026, and potentially longer. The financial system's ability to smoothly handle recent funding stress points (like corporate tax day) suggests that reserves are still abundant enough to support a prolonged QT timeline.

Contrary to the push for an "efficient" (smaller) Fed balance sheet, an abundance of reserves increases bank safety. Bank reserves are immediately accessible liquidity, unlike Treasuries which must be sold or repoed in a crisis. This inherent buffer can make the banking system more resilient.

The Fed plans to align its balance sheet duration with the Treasury's by reducing its holdings of long-term bonds. This would steepen the yield curve by raising long-term rates (hurting mega-caps) while simultaneously cutting the Fed Funds rate to ease pressure on smaller businesses with floating-rate debt.

A highly technical insight reveals Kevin Warsh favors returning to the pre-2008 monetary system of "scarce reserves." This would be a major operational change from the current "ample reserves" framework, requiring the Fed to actively manage daily liquidity and significantly shrink its balance sheet to exert policy discipline.

While presidents focus on interest rates, a Fed Chair like Kevin Warsh has limited sway as one of 12 votes. His real impact will be on technical areas like the Fed's balance sheet, where he has stronger personal convictions and faces less political scrutiny.
