IMF 2009 observes borrowers de facto bear FX risk in local-currency lending mismatches but emphasizes macroeconomic stability and institutional quality—not assignment of risk—as key to sustainability.
The IMF's 2009 analysis identifies that currency mismatches—where borrowers take foreign currency loans while earning in local currency—arise from a combination of borrower expectations (e.g., stable or appreciating exchange rates), interest rate differentials, exchange rate regime credibility, bank funding structures, and institutional quality. It notes that borrowers bear FX risk in practice, often underestimating depreciation risks due to optimistic expectations or implicit bailout hopes, but does not prescribe who *should* bear the risk; instead, it highlights systemic vulnerabilities and calls for macroeconomic stability, improved institutional frameworks, and prudent financial regulation to mitigate mismatch-related risks to debt sustainability.
