US Debt-Service Shock Likely to Steepen Yield Curve and Pressure Risk Assets Globally

Moderate confidence (70%)
Risk direction: volatile · Impact: HIGH
Full prediction
The revelation that US annual interest costs have surpassed $1 trillion is likely to reinforce expectations of sustained high issuance and limited fiscal space, steepening the yield curve over the coming week. Investors will reprice long-duration risk, pressuring equities, high-yield credit, and leveraged sectors worldwide. Emerging markets will face higher external funding costs just as energy-import bills climb, forcing central banks toward pro-cyclical tightening. Confirmation would be a further rise in 10–30-year Treasury yields, underperformance of growth stocks and high-yield bonds, and widening EM sovereign spreads; a dovish communication pivot or safe-haven flows overwhelming supply could flatten yields instead.
