Contrary to fears of a spike, a major rise in 10-year Treasury yields is unlikely. The current wide gap between long-term yields and the Fed's lower policy rate—a multi-year anomaly—makes these bonds increasingly attractive to buyers. This dynamic creates a natural ceiling on how high long-term rates can go.

If the Fed cuts rates too aggressively during a productivity boom, the bond market will likely sell off long-duration bonds. This "bear steepening" would raise long-term yields that influence mortgages and corporate borrowing, tightening financial conditions and counteracting the Fed's intended easing.

In the early stages of a Fed easing cycle, short-term rates fall while long-term rates remain sticky, causing the yield curve to steepen. The rally in long-dated bonds only occurs much later, after investors get comfortable with low rates and begin chasing carry trades.

A common misconception is that Fed rate cuts lower all borrowing costs. However, aggressive short-term cuts can signal future inflation, causing the 10-year Treasury yield to rise. This increases long-term rates for mortgages and corporate debt, counteracting the intended economic stimulus.

The Federal Reserve faces "fiscal dominance," where government debt dictates monetary policy. With a massive amount of US debt maturing in 2026, the Fed will be forced to lower interest rates to make refinancing manageable, regardless of other economic indicators. The alternative is national insolvency.

Fed rate cuts primarily lower short-term yields. If long-term yields remain high or rise, this steepens the curve. Because mortgage rates track these longer yields, they can actually increase, creating a headwind for housing affordability despite an easing monetary policy.

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.

The bond market is a better indicator for mortgage rates than the Fed. The current spread between 5-year and 10-year Treasury notes implies that investors expect the 5-year note's yield to be 100 basis points higher in five years than it is today. Since mortgage rates are closely tied to these yields, this suggests a potential for higher, not lower, mortgage rates in the medium term.

The Federal Reserve is executing an underappreciated policy of shortening its balance sheet duration. This supports short-term rates while pressuring long-term bonds, causing a yield curve steepening that creates a structural headwind for long-duration assets like crypto and high-growth technology stocks.
