The dollar index rose to 99.9 on Wednesday, the highest in three weeks, as Federal Reserve policymakers struck a hawkish tone in their rate hold and persistent geopolitical tensions supported the safety of the greenback. The Fed held its policy rates unchanged as expected by markets, but three FOMC members dissented against the easing bias in the central bank's signal. This increased the thresholds for regional Fed presidents, known for being more hawkish, to vote for an eventual cut. Meanwhile, President Trump signaled that an agreement to lift the blockade of tankers in the Persian Gulf will only be lifted with an Iranian nuclear agreement, adding more impasses to the conflict and supporting global demand for the dollar. The Bank of Canada signaled it does not see domestic inflation de-anchoring in its rate hold, although the BoJ delivered hawkish remarks in its meeting. Both the ECB and BoE decide their rates tomorrow.
