When markets price in central bank tightening that is not actively delivered, lower-carry currencies lack the necessary buffers to absorb macro shocks. Investors are consequently pushed to migrate capital toward resilient, higher-carry candidates where substantial policy rates have already been established.
During recent market turmoil, EMFX downside was driven primarily by bond market positioning rather than currency-specific indicators. Sell-offs in rates markets triggered wider asset adjustments, with rate volatility and specific exposures like diesel or gas further amplifying losses across emerging currencies.
Elevated yields force emerging market sovereigns to make increasingly large primary balance adjustments to offset compounding interest payments. Even without major forecast fiscal widening, staying at wide post-COVID deficits under high borrowing costs creates a persistent fiscal trap that prevents yields from easily retreating.
Steepening curves and surging long-end yields act as endogenous tightening mechanisms that dampen financial conditions directly. Because higher long-term yields do part of the restrictive work, front-end rate curves begin pricing in less aggressive policy rate hikes by central banks.
