Economic Impact of Tariffs and Tax Cuts

Recent projections suggest that the tariffs instituted by President Trump alongside significant tax cuts from the GOP will have differing effects on the economy. According to the latest reports from the Congressional Budget Office (CBO), there’s an anticipated increase in economic volatility for the remainder of 2025.

While tariffs are likely to suppress economic growth, the tax cuts are expected to stimulate it by enhancing capital stock and productivity.

In the longer term, the tax cuts, along with the labor provisions in a major legislation, should increase labor supply. However, the CBO has lowered its short-term projections, showing that employment has seen a sharp decline, with only an average of 29,000 jobs being added per month since June.

This year’s economic outlook appears weaker than earlier predictions, although next year’s projections look more promising. The Gross Domestic Product (GDP) is forecasted to drop from the predicted 1.9% growth rate for this year. Notably, the World Bank had estimated growth at 1.4% in June, while the International Monetary Fund forecasted 1.9% in July.

The actual growth projection is now 0.5 percentage points lower based on the latest CBO numbers. The official budget scorer mentioned that “the negative impact on output caused by new tariffs and low net immigration is offsetting the positive effects from this year’s Settlement Act provisions.”

Generally, tariffs tend to dampen growth by increasing costs for both producers and consumers, whereas tax cuts can stimulate it by encouraging more investment and consumption.

Looking ahead, GDP growth projections have improved for 2026, now estimated at 2.2%, compared to the 1.8% forecasted in January.

Inflation is also expected to rise, hitting 3.1% this year and 2.4% next year, both figures above earlier estimates. The Consumer Price Index showed a yearly increase of 2.9% in August, a slight rise from July’s 2.7%.

Tariffs and tax cuts also significantly impact public deficits. This fiscal year, deficits are projected to approach $2 trillion, tapering to around $1.8 trillion by year-end. The Tax Cuts Act may contribute $3.4 trillion to the national deficit over the next decade, resulting in a tax revenue drop of $4.5 trillion. If tariffs stay in place, they could limit the deficit’s growth by $4 trillion.

Revenue from tariffs has reached record levels recently, climbing to $30 billion in August, which is approximately triple the revenue generated from the new trading regime.

The CBO previously predicted that debts held by the public might increase from about 100% of GDP to nearly 120% by 2035, although this estimate does not account for the impact of tariffs.

Concerns are growing among investors and economists regarding the sustainability of rising U.S. deficit levels. There’s a warning that increased political pressure from the Trump administration could lead the Federal Reserve to monetize public debt, potentially triggering a capital exodus similar to what occurred when bond yields surged in April following the announcement of new tariffs.

Harvard economist Jeffrey Frankel commented on this, noting, “We may have exhausted our willingness to accumulate infinitely among global investors [Treasury]. The U.S. might find itself in a situation where chronic deficits eventually necessitate monetization and currency depreciation.”

Since the beginning of the year, the DXY Dollar Index has dropped by about 11%. Additionally, the nominal broad dollar index has fallen roughly 7%. This decline seems contrary to the theoretical expectation that tariffs should strengthen domestic currency rather than depreciate it.
