Quantitative Easing (QE) forced massive, often uninsured deposits onto bank balance sheets when loan demand was weak. These deposits were highly rate-sensitive. When the Fed began raising rates, this "hot money" quickly fled the system, contributing to the banking volatility seen in March 2023.

After a decade of zero rates and QE post-2008, the financial system can no longer function without continuous stimulus. Attempts to tighten policy, as seen with the 2018 repo crisis, immediately cause breakdowns, forcing central banks to reverse course and indicating a permanent state of intervention.

The market's hawkish repricing for the Bank of Canada is likely temporary due to underlying economic slack and trade risks. In contrast, Australia's RBA is a more credible potential hiker, supported by resilient growth and higher inflation, making it a "true soft landing candidate" and a better bet for policy tightening.

Former RBI Governor Raghuram Rajan points to a historical pattern preceding every major financial crisis: a U-shape in monetary policy. An extended period of easy money builds up risk, and the subsequent tightening phase triggers the collapse. This framework helps identify periods of heightened systemic vulnerability.

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.

The impending halt of the Fed's balance sheet reduction (QT) is not a reaction to a major economic crisis, but a technical necessity to prevent stress in short-term funding markets as bank reserves become scarce. The Fed is preemptively avoiding a 2019-style repo spike, signaling a quiet return to mild balance sheet expansion.

A recent global fixed income sell-off was not triggered by a single U.S. event but by a cascade of disparate actions from central banks and data releases in smaller economies like Australia, New Zealand, and Japan. This decentralized shift is an unusual dynamic for markets, leading to dollar weakness.

The Fed's decision to end quantitative tightening (QT) in December, not immediately, could strain funding markets. Investors should monitor rising overnight repo usage and widening SOFR-Fed funds spreads as key indicators of impending weakness in speculative equities.
