The Bureau of Economic Analysis confirmed Thursday that the U.S. economy grew at an annualized rate of just 0.7 percent in the fourth quarter of 2025, the weakest quarterly performance since the pandemic-era contraction of 2020. Full-year GDP growth for 2025 came in at 2.1 percent, down from 2.9 percent in 2024.

The numbers tell a story of an economy that was already decelerating before the Iran conflict, the Hormuz closure, and the oil price spike added new headwinds. Consumer spending slowed. Business investment contracted for the first time in six quarters. Net exports deteriorated as tariff uncertainty weighed on trade flows.

What Drove the Slowdown

Three factors account for most of the deceleration.

First, the consumer, who accounts for roughly 70 percent of GDP, pulled back. Real personal consumption expenditure grew at just 1.2 percent in Q4, down from 3.1 percent in Q3. The slowdown was concentrated in durable goods (automobiles, appliances, furniture), which are sensitive to interest rates. With mortgage rates above 6.5 percent and auto loan rates near 8 percent, big-ticket purchases have become significantly more expensive.

Second, business fixed investment declined 0.8 percent, dragged down by falling spending on equipment and structures. The tariff environment has created a planning paralysis for companies that depend on global supply chains. When the rules change quarterly (and are litigated simultaneously in federal court), capital allocation decisions get deferred. The result is visible in the data: companies are sitting on cash rather than investing it.

Third, the trade deficit widened as imports rose and exports fell. The strong dollar, sustained by relatively high U.S. interest rates compared to other advanced economies, has made American goods more expensive abroad while making imports cheaper. The tariffs have not reversed this dynamic; they have complicated it by raising input costs for American manufacturers who rely on imported components.

The War Economy

The Q4 data reflects conditions that prevailed before Operation Epic Fury began on February 28. The economy that enters the Iran conflict is not the economy that entered previous military campaigns.

In 2003, when the Iraq War began, the U.S. economy was recovering from a mild recession and had room to absorb war spending as fiscal stimulus. Interest rates were low. Oil was at $30 per barrel. The labor market had slack.

In 2026, the economy is operating near full employment with limited spare capacity. Interest rates are elevated. Oil has tripled from its pre-war level. The federal deficit is already running at approximately 6 percent of GDP before war supplemental spending is added.

War spending will boost GDP in the short term because military expenditure counts as government consumption in the national accounts. But this is an arithmetic artifact, not genuine economic health. The spending is funded by borrowing, not revenue, and the inflationary effect of higher energy prices will offset whatever GDP boost the military spending provides.

The Recession Question

The debate over whether the United States will enter a technical recession (two consecutive quarters of negative GDP growth) is less important than the underlying reality: the economy is weak and getting weaker.

Moody's puts recession probability at 42 percent. J.P. Morgan estimates 35 percent. Bloomberg consensus is at 30 percent. These numbers have all risen since the Iran conflict began and will continue to rise as long as oil remains above $100.

The more relevant question is how deep any downturn might be. A shallow recession driven primarily by energy costs and trade uncertainty would be painful but manageable. The labor market remains tight, household balance sheets are relatively healthy, and the banking system is well-capitalized.

A deeper recession, triggered by a sustained oil shock, a credit event, or a loss of business confidence, would be considerably more difficult to manage because the Fed's primary tool (rate cuts) is constrained by inflation and the fiscal tool (deficit spending) is constrained by a debt-to-GDP ratio that already exceeds 120 percent.

The 0.7 percent growth figure is not a crisis. It is a warning. The economy entered 2026 with less resilience than it needed, and the geopolitical environment has since become significantly more demanding. How policymakers respond in the next two quarters will determine whether the warning is heeded or ignored.
