The core idea
A stronger dollar can tighten financial conditions for borrowers with dollar-denominated liabilities because local-currency revenues buy fewer dollars needed for debt service.
What is happening underneath
It can also coincide with capital outflows and higher U.S. yields.
How investors should read it
Countries with stronger reserves, lower external debt and credible policy frameworks may be more resilient.
The same market move can carry different information depending on which maturity, issuer and risk premium is changing. Read the question together with the underlying concepts rather than treating one price move as a universal signal.
