Are we being too complacent about US risk to global market stability?

Goldman Sachs warns that markets have largely unwound the spring spike in its “US risk premium” — a measure of political and institutional unease that jumped after April’s reciprocal tariff announcement and Fed chair speculation — and that the rapid retreat since late July may have left investors complacent. Using a three-shock model that isolates a political/institutional component, Goldman says the same mix that produced dollar weakness, rising long-term Treasury yields and US equity underperformance earlier this year could reappear if triggers like the December/January Fed chair appointment, hints of 50bp cuts from Governor Miran or renewed fiscal/tariff disputes resurface. If those risks return, expect a classic political-risk reaction (weaker dollar, gold rally, higher long yields, curve steepening and US underperformance); if not, the premium could vanish, bolstering front-end yields and the dollar — and with current FX and rates volatility subdued, protection against a renewed US structural shock is relatively inexpensive.

Analysis

Goldman Sachs reports that its "US risk premium"—a modelled measure of political and institutional unease that spiked after April's reciprocal tariff announcement and Fed chair speculation—has largely retreated since late July, leaving markets calmer and volatility across FX and rates subdued. The bank's three-shock decomposition attributes April's unusual mix (falling US equities, a weaker dollar and rising long-term Treasury yields) predominantly to the political/institutional shock rather than pure growth or monetary-policy moves.

Goldman highlights specific potential reignition points: the Fed chair appointment expected in December/January, Governor Miran's signalling of potential 50bp cuts, and renewed fiscal or tariff disputes including court challenges or tax-rebate politics. When worries peaked earlier, the response pattern was dollar weakness, gold rallies, rising long yields and curve steepening, with US equities underperforming Europe and Japan; the current calm therefore could be a source of vulnerability rather than confirmation of resolved risks.

With FX and rates volatility low, the bank notes protection against a return of US structural worries is relatively inexpensive; the alternative path would see the premium vanish, supporting front-end yields and the dollar. Investors should weigh the low cost of hedges against the nonzero probability that political or institutional triggers re-emerge.

Key Decisions for Investors

• Consider buying inexpensive protection in FX and rates markets while volatility is subdued to hedge a potential recurrence of US political/institutional shocks, Monitor the Fed chair appointment process and any widening split in the rate-setting committee—these are high-probability catalysts for renewed risk premium, Reduce concentrated US equity exposure or add relative exposure to regions that outperformed during the spring episode (Europe, Japan) if you want to limit downside from a political-risk selloff, Position duration and front-end cash carefully: if the US risk premium disappears, front-end yields could rise, so avoid forced long-duration exposure without hedges
