The Dollar Index (DXY) surged to 105.20 on Monday — a 2026 high — as two reinforcing forces drove demand for the greenback. First, Friday's March PCE print of 2.7% headline (2.6% core) eliminated residual hopes for a June Fed rate cut, pushing rate differentials further in the dollar's favor. Second, the escalation of the Iran conflict on its 67th day triggered classic safe-haven flows into dollar-denominated assets.
EUR/USD fell to 1.1696, its lowest level since mid-February, as the eurozone economy faces a twin headwind of energy-import costs and weakening export demand. GBP/USD dropped to 1.3541 despite the Bank of England's relatively hawkish posture. USD/JPY rose to 157.80, prompting verbal intervention from Japan's Finance Ministry, with Vice Minister Atsushi Mimura warning that 'one-sided, rapid moves in the yen are undesirable.'
Emerging Market Pressure
Emerging-market currencies suffered broad-based selling. The Turkish lira hit a record low, the South African rand fell 1.8%, and the Brazilian real declined 1.2%. The MSCI EM Currency Index dropped 0.7% — its worst session in three weeks. EM central banks face an impossible trinity: cutting rates to support growth, defending currencies against the dollar, and managing imported inflation through energy prices.
Rate Differential Dynamics
The repricing of Fed expectations is the primary structural driver. With the terminal rate now priced at 3.25% — implying just two more cuts this cycle — versus the ECB expected to cut twice more to 2.25%, the 2-year rate differential between U.S. and German government bonds has widened to 195 basis points, the most dollar-favorable spread since Q4 2024. This makes dollar carry trades increasingly attractive for leveraged investors.
Outlook
Deutsche Bank FX strategist George Saravelos raised his Q2 DXY forecast to 106 from 103, writing that 'the combination of relative rate advantage and geopolitical premium creates a compelling dollar story.' The risk to the bullish dollar view is a rapid de-escalation of the Iran conflict, which would simultaneously remove the haven bid and allow the Fed to resume its cutting cycle. Wednesday's FOMC minutes and Friday's employment report are the key events for dollar direction this week.
