An Update from the Congressional Budget Office. *
INTRODUCTION:
The Congressional Budget Office’s November 2025 update shows that rapidly changing tariff policies have significantly reshaped federal budget projections. As of mid November, the effective U.S. tariff rate is about 14 percentage points higher than a year earlier, and CBO now estimates that tariffs implemented in 2025 could reduce federal deficits by roughly $3.0 trillion over the next decade, including lower interest costs. The report explains why these estimates are smaller than earlier projections, highlights exemptions and policy shifts affecting major trading partners. It also underscores the considerable uncertainty surrounding the long term fiscal and economic effects of today’s unprecedented tariff levels.
