Economic Data and Tariff Ruling Disrupt a Quiet Week
A shortened, calm week was suddenly shaken on Friday as both economic data and a Supreme Court ruling on tariffs surprised the markets. Fourth Quarter GDP grew only 1.4%, well below expectations of 2.8%, driven by weaker government spending, while PCE inflation for Dec ’25 edged higher. The Supreme Court decision invalidated a large portion of existing global tariffs. In response, the administration announced a temporary additional 10% tariff under Section 122 of the Trade Act of 1974, to remain in effect for 150 days.
The Supreme Court’s decision to strike down most global tariffs was widely expected, but it still introduces new uncertainties for investors. Key questions remain around future trade actions and whether previously collected duties could be refunded—an outcome that may affect corporate earnings, inflation pressures, and especially the bond market. Our latest commentary explores what the ruling means for markets and why a disciplined, diversified approach remains essential as tariff related developments continue to unfold.
