Tariff Ruling Highlights Delicate Economic Balance

Our framing and outlook for the U.S. economy and markets in recent months can be summarized by what I like to call the “three Bs”: Bifurcation and Broadening, all within the context of a delicate economic Balance.

The past three years have been defined by a bifurcated, or “K-shaped,” economy in which the gap between the companies and consumers benefitting from high interest rates and those that are punished by them has continued to widen. This bifurcation—ignited by the Federal Reserve’s decision to raise its benchmark interest rate from 0.25 percent in March of 2022 to as high as 5.5 percent in July 2023—was only compounded by the rapid rise of artificial intelligence (AI) as massive investment into the sector pushed the “Magnificent Seven” and other technology winners to new heights.

More recently, however, the historically narrow economy and markets have begun to exhibit gradual signs of broadening as the U.S. central bank has moved to cut rates by a total of 1.75 percent since 2024. Small-Cap and Mid-Cap stocks have significantly outperformed the broader market over the past several months, marking a sharp reversal from their performance over the past several years, as investors have increasingly rotated out of mega-cap technology stocks and into more economically sensitive companies.

Nevertheless, we continue to note that much of this optimism remains in a delicate balance amid a tug-of-war of tensions between steady economic growth, persistent labor market weakness and stubborn inflation, which remains stuck above the Fed’s 2 percent target since the end of 2023. A landmark Supreme Court ruling on Friday—which deemed the Trump administration’s use of the International Emergency Economic Powers Act (IEEPA) to impose tariffs unlawful—cast further uncertainty over the markets and economy, leaving billions of tariff revenue in limbo, according to the Budget Lab at Yale.

Factor in the ever-present geopolitical risks (with escalating tension between the U.S. and Iran the latest example), the lingering impacts of the record-setting government shutdown in the fourth quarter of 2025, and mounting worries over the sustainability of AI spending, and the long-term economic picture looks increasingly unclear.

This delicate balance was on display once again last week, as a hotter than expected December inflation reading clashed against weaker than expected U.S. gross domestic product (GDP) data. The economy grew at an annual rate of 1.4 percent in the fourth quarter of 2025, according to the latest figures, significantly lower than the 2.8 percent growth many economists had anticipated, as the historic 43-day government shutdown, decelerating consumer spending and sticky inflation weighed on overall performance.

More volatility remains on the horizon. Following the Supreme Court’s tariff ruling, U.S. President Donald Trump signaled he would not back down on his trade agenda, immediately pivoting to alternative legal authorities that the court did not invalidate, including a new 15 percent global tariff under the Trade Act of 1974. Unlike the tariffs that were recently struck down, however, these new levies are capped at 150 days unless Congress approves an extension.

Questions remain as to whether what the Penn Wharton Budget Model estimates to be roughly $175 billion in already collected tariff revenue will now be subject to potential refunds. Without IEEPA tariffs, the overall average effective tariff rate will fall to 9.1 percent, according to the Budget Lab at Yale, which remains the highest since 1946 excluding 2025. Had the IEEPA tariffs remained in place, this figure would have reached 16 percent, the highest since 1936. With the new announcement of 15 percent Section 122 tariffs, the rate is estimated to reach 13.7 percent for the next 150 days. The fates of various trade deals struck between the U.S. and its key trading partners also remain in question, as does the overall implementation of the 15 percent tariffs.
