The desk brief
On 21 Sep 2026 the US Dollar Index (DXY) traded near 100.35 following the Federal Reserve's 16 Sep 2026 25bp rate increase to a 3.75%-4.00% target range, reinforcing a stronger-dollar environment that raises the local-currency cost of USD debt for borrowers outside the US.
A stronger DXY raises the local-currency cost of servicing and rolling USD-denominated debt because more domestic currency is required per dollar. Long-duration eurobonds are vulnerable via duration and dollar-liquidity channels, while importers face immediate FX funding pressure. Oil exporters with USD receipts are relatively more insulated, but non-resource importers and long-tenor sovereigns can see financing stress if the dollar rally persists.
Incoming Fed speeches and US inflation data; changes in Fed dot plots or further rate moves within the next few weeks.
