The 2026 Fiscal Cliff is Already Breaking Bond Markets

The bond market has stopped waiting for the 2026 midterms. As of November 18, 2025, the 10-year Treasury yield has carved a jagged path toward 4.78 percent, defying the soft landing consensus that lulled investors into a false sense of security last year. We are witnessing the return of the term premium. This is a technical reality that Michael Zezas, Global Head of Fixed Income Research at Morgan Stanley, signaled as a risk in 2024. Today, it is a systemic threat.

The Mathematical Trap of the 2026 Midterms

Math does not care about campaign promises. The expiration of the Tax Cuts and Jobs Act (TCJA) in 2026 is no longer a distant policy debate. It is a looming liquidity vacuum. Yesterday, November 17, 2025, the Treasury saw a tail in the 20-year bond auction that signaled deep institutional hesitation. Investors are demanding a higher yield to hold long-dated paper because the fiscal deficit is now structurally entrenched at 7 percent of GDP.

The current narrative has shifted from inflation control to debt sustainability. According to the latest Bloomberg market data, the cost of servicing US debt has officially surpassed the defense budget. This is the definition of fiscal dominance. When interest payments consume more than national security, the Federal Reserve loses its ability to dictate terms to the market. The market dictates terms to the Fed.

The Maturity Wall and Duration Risk

Corporate America is hitting the wall. Throughout 2024, firms bragged about locking in low rates. Those hedges are expiring. In the last 48 hours, high-yield spreads have begun to widen as analysts realize that refinancing in 2026 will happen at double the previous coupons. This is not a slow burn. It is a cliff. Per Reuters finance reports, the volume of corporate debt maturing in the next 14 months exceeds 2.1 trillion dollars. The math for 2026 yields does not add up for the bulls.

Deficit Spending Meets the Liquidity Crunch

Volatility is the new alpha. The assumption that the Federal Reserve would bail out the long end of the curve has evaporated. In 2024, the market expected six rate cuts. In November 2025, we are lucky to have seen two. The persistence of core services inflation, coupled with an unchecked fiscal trajectory, has forced the Fed into a corner. They cannot cut rates into a fiscal expansion without risking a currency collapse.

Institutional players are rotating. We are seeing a massive shift out of long-duration bonds and into short-term cash equivalents and inflation-protected securities. The data below illustrates the stark contrast between the market’s 2024 optimism and the cold reality of November 2025.

The Ghost of the 2017 Tax Cuts

Politics is now a credit event. The 2026 expiration of the TCJA represents a 4 trillion dollar swing in the federal balance sheet over the next decade. If Congress extends the cuts, the deficit explodes. If they let them expire, the economy faces a massive tax hike during a period of slowing growth. This is the ‘Fiscal Trap’ that the bond market is currently pricing in. According to internal SEC filings regarding municipal bond risks, local governments are already adjusting their 2026 budgets to account for a significant drop in federal subsidies.

The mechanism of this decline is simple. As the federal government issues more debt to cover the gap, it crowds out the private sector. Bank reserves are being depleted to soak up Treasury auctions. This reduced liquidity leads to higher volatility in equity markets, which explains why the VIX has stayed stubbornly above 20 for the past three weeks despite decent corporate earnings. The plumbing of the financial system is clogged with government paper.

Navigating the 2026 Liquidity Crunch

Passive investing is dead. The era of ‘buying the dip’ in 60/40 portfolios is being replaced by active duration management. Investors must look at the ‘Real Yield’—the nominal yield minus inflation expectations. In November 2025, real yields are at their highest levels since the 2008 crisis. This makes cash a weapon, not a drag. Holding dry powder allows for the exploitation of the forced liquidations we expect to see as the 2026 maturity wall approaches.

The next major milestone for the market is January 15, 2026. That is when the Congressional Budget Office will release its updated baseline. If that report confirms a deficit trajectory exceeding 8 percent, expect the 10-year yield to test 5.25 percent immediately. Watch the 2-year/10-year spread. If it steepens aggressively, the market is telling you that the fiscal game is up. Position for the crunch now, or be the liquidity for someone else later.
