Emerging-market currencies split Monday as investors weighed reports of reduced U.S.-Iran friction against a carry trade unwind that hit Latin American assets hardest.

Asian emerging-market names firmed against the dollar. Latin American currencies fell, pressured by the same dynamic that has defined this rate cycle: a Federal Reserve holding steady at restrictive levels makes the yield pickup from high-carry EM positions harder to justify when the dollar itself offers real return.

Reports of reduced U.S.-Iran friction eased some geopolitical risk premium that had kept oil elevated and the dollar bid. Prior Strait of Hormuz tensions had spiked crude, splitting EM exposure along energy lines—exporters benefiting, importers absorbing the cost. Stabilizing oil removes that tailwind for commodity-linked currencies while relieving pressure on energy importers.

U.S. Treasury yields held firm, compressing the incremental pickup available from EM bonds. Spread compression on higher-quality EM sovereign debt has stalled, and duration risk in EM fixed-income portfolios remains acute in a higher-for-longer environment. Investors are demanding greater compensation on longer-dated pa and issuers with weak fiscal positions face spread widening as a result.

The dollar has erased previous 2026 gains for many EM currencies. That reversal compounds debt-servicing pressure on dollar-denominated EM borrowers, tightening their effective cost of capital even without a fresh rate hike.
