Key Takeaways

• Supreme Court nullified Trump’s IEEPA tariffs, boosting equities

Pulse Analysis

The Supreme Court’s reversal of the IEEPA tariffs removes a temporary fiscal cushion that had helped mask the United States’ growing budget gap. Without that revenue stream, Treasury officials may face heightened pressure to issue more debt, especially at the longer end of the curve. Market participants are already pricing a modest rise in the 10‑year yield, and analysts warn that continued uncertainty could push yields toward 4.25%, prompting a re‑steepening of the yield curve and reshaping fixed‑income strategies.

Currency markets reacted with a subtle dollar decline as investors gravitated toward higher‑beta, growth‑linked currencies. The Swedish krona and Australian dollar led the rally, reflecting optimism for export‑driven economies. However, the Canadian dollar and Mexican peso lagged due to pending USMCA negotiations, while broader FX sentiment remains vulnerable to geopolitical shocks, notably any escalation with Iran that could spike oil prices and re‑strengthen the greenback.

Equity markets welcomed the news, with U.S. futures gaining roughly 0.7% and Germany’s DAX futures up 0.5%, as corporations anticipate relief from tariff‑related cost pressures. The positive tone extends to Europe, where foreign investors have been buying eurozone stocks at their strongest pace since late 2021. Provided energy prices stay stable, the current rotation into non‑U.S. equities could persist, offering investors diversified exposure amid the evolving policy landscape.
