One of the key risks to the 2026 outlook is a 'demand upside' scenario where growth accelerates unexpectedly. This would keep inflation hot and likely force the Fed to pause or even reverse its planned rate cuts, creating a significant shock for financial markets that have priced in a more accommodative policy.

While election-year fiscal stimulus may boost 2026 growth, it sets the stage for a potential inflation problem in 2027. The combination of lagged effects from the stimulus, tariffs, and restrictive immigration could cause overheating. Due to policy lags, the consequences won't be fully felt until after the election year.

The outlook for 2026 is significantly more optimistic than 2025, primarily due to fiscal policy. Deficit-financed tax cuts are expected to add nearly half a percentage point to GDP growth. This stimulus, not AI, is seen as the main force lifting the economy from below-potential to at-potential growth.

The "One Big Beautiful Bill Act" front-loads tax cuts, boosting consumer income and GDP in 2026. However, its spending cuts are delayed until later in the decade, meaning the bill will become a drag on economic growth in subsequent years as those austerity measures take effect.

Despite weak underlying economic data, the probability of a recession is not over 50% due to anticipated policy stimulus. This includes Fed rate cuts, major tax cuts, and deregulation, which are expected to provide significant, albeit temporary, economic support.

Large, ongoing fiscal deficits are now the primary driver of the U.S. economy, a factor many macro analysts are missing. This sustained government spending creates a higher floor for economic activity and asset prices, rendering traditional monetary policy indicators less effective and making the economy behave more like a fiscally dominant state.

The 2026 US economic forecast is not a simple slowdown but a tale of two halves. A weaker first half is expected due to lingering effects of tariffs and policy. A recovery is projected for the second half as spending remains resilient and the economy adjusts.

J.P. Morgan highlights a confluence of factors in 2026 that could create significant inflationary pressure. These include planned tax cuts, major national events like the FIFA World Cup and America's 250th birthday, and potential shifts in immigration policy, creating a powerful fiscal tailwind.

The US economy is seeing a rare combination of high government deficits, massive AI-driven corporate investment, and bank deregulation. If the Federal Reserve also cuts rates based on labor market fears, this confluence of fiscal, corporate, and monetary stimulus could ignite unprecedented corporate risk-taking if growth holds up.
