U.S. Congressional Budget Office Raises 2026 Fiscal Year Deficit Forecast to $2.1 Trillion
The U.S. Congressional Budget Office has raised its forecast for the federal deficit in fiscal year 2026 by $200 billion to $2.1 trillion, significantly higher than the $1.9 trillion projected in February.
The widening deficit is primarily due to tariff and customs revenue falling far short of expectations. Following a Supreme Court ruling in February that determined the Trump administration lacked authority for certain tariffs, the CBO estimates that tariff-related revenue will be about $250 billion lower than previously forecasted in 2026.
Spending is close to the February baseline, with a revenue shortfall of approximately $200 billion. The deficit for the first 10 months has reached about $1.8 trillion.
The further widening of the deficit will increase policy pressure on the White House and Congress regarding government spending, taxation, and debt paths.
Interest expenditures have increased by $117 billion year-on-year in the first 10 months.
In market mechanisms, higher deficit expectations are driving up long-term interest rates and concerns about debt sustainability, leading funds to flow into safe-haven assets, putting pressure on fiscal expansion space.
This forecast is based on data up to the end of July.

The Congressional Budget Office, as a non-partisan agency, directly attributes the deficit increase to a significant decline in tariff revenue, exposing the fiscal impact of judicial risks in trade policy.
The capital path reflects that after the shortfall in tariff revenue expectations, the government can only rely more on debt financing, motivated by the need to maintain established spending while facing higher interest costs and political negotiation pressures.
Historically, cases where changes in trade or tax policy have led to significant revisions in deficit forecasts are currently in a recalibration phase following judicial rulings that alter the structure of fiscal revenue.
Essentially, this represents a tightening of fiscal paths, with the mechanism being that when expected revenue sources are negated by the courts, the deficit and debt trajectory immediately deteriorates, forcing policy debates to focus on spending cuts or alternative revenue sources.
