The Fed's plan to reinvest maturing mortgage-backed securities (MBS) into Treasury bills is a stealth liquidity injection. The US Treasury can amplify this effect by shifting issuance from long-term bonds to short-term bills, which the Fed then absorbs. This is a backdoor way to manage rates without formal QE.
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.
The Fed has a clear hierarchy for managing liquidity post-QT. It will first adjust administered rates like the Standing Repo Facility (SRF) rate and use temporary open market operations (TOMOs) for short-term needs. Direct T-bill purchases are a more distant tool, reserved for 2026, as the system is not yet at 'reserve scarcity'.
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.
While the market fixates on rate cuts, the Fed's decision to reinvest mortgage-backed security proceeds only into T-bills adds significant duration risk to the market monthly. This is a subtle but impactful form of hawkish policy that counteracts easing narratives.
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.
According to BlackRock's CIO Rick Reeder, the critical metric for the economy isn't the Fed Funds Rate, but a stable 10-year Treasury yield. This stability lowers volatility in the mortgage market, which is far more impactful for real-world borrowing, corporate funding, and international investor confidence.
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.
Over the past few years, the Treasury Department and the Federal Reserve have been working at cross-purposes. While the Fed attempted to remove liquidity from the system via quantitative tightening, the Treasury effectively reinjected it by drawing down its reverse repo facility and focusing issuance on T-bills.
The Federal Reserve is expected to buy approximately $280 billion of T-bills in the secondary market next year. This significant demand source provides the Treasury with flexibility, allowing it to temporarily exceed its long-term T-bill share target of 20% without causing market disruption.
Lacking demand for long-term bonds, the Treasury issues massive short-term debt. This requires a larger cash balance (TGA) to avoid failed auctions, draining liquidity from the very markets needed to finance this debt, creating a self-reinforcing crisis dynamic.
