The US Dollar (USD) exhibited broad-based strength on Wednesday, driven by a combination of Federal Reserve (Fed) policy caution, escalating geopolitical tensions in the Middle East, and surging oil prices. The USD/CAD pair traded essentially flat near 1.3680 after a brief spike to 1.3710, with the Bank of Canada (BoC) maintaining its overnight rate target at 2.25% for the sixth consecutive meeting, in line with consensus expectations. BoC Governor Tiff Macklem indicated that the central bank would 'look through' the immediate inflation impact of higher energy prices due to the Iran war, but warned that policy 'may need to be nimble' if elevated crude prices feed into broader inflation, potentially necessitating consecutive rate hikes. The BoC's baseline scenario assumes crude oil prices will fall back to $75 per barrel by mid-2027, suggesting only small changes in the policy rate under current assumptions [1].
On the US side, President Donald Trump heightened market anxiety with a Truth Social post threatening fresh action against Iran, accompanied by an AI-generated image and strong rhetoric. The post came as US-Iran talks remained stalled and the Strait of Hormuz blockade continued to halt roughly 20% of global oil shipments, pushing West Texas Intermediate (WTI) crude above $100 per barrel. This supported the commodity-linked Canadian Dollar and capped further gains in USD/CAD, even as the safe-haven Greenback saw brief bids. Market attention shifted to the Fed's upcoming decision, with the federal funds rate widely expected to remain in the 3.50% to 3.75% range [1][2].
The NZD/USD pair weakened, trading around 0.5840 and down 0.76% on the day, as investors anticipated the Fed would keep rates unchanged for the fourth consecutive meeting. The prospect of a hawkish Fed stance, emphasizing persistent inflation risks, bolstered the USD and pressured risk-sensitive currencies like the New Zealand Dollar. Geopolitical tensions and the resulting rise in oil prices reinforced expectations of a prolonged higher-rate environment. Additionally, safe-haven demand for the USD remained firm, with the Greenback showing the strongest performance against the NZD, up 0.78% on the day [2].
GBP/USD also fell toward 1.3480 as the USD gained strength ahead of the Fed decision. The United Arab Emirates' (UAE) exit from OPEC further fueled safe-haven demand for the USD, exacerbating concerns over global energy supply amid the ongoing Iran war. The UAE's departure from OPEC was described as a blow to the oil producers' group, widening a rift with Saudi Arabia and undermining OPEC's control over global oil supplies [3].
According to BNY's Bob Savage, the USD entered the FOMC meeting with its first five-day net purchase streak in three months and rising demand for USD cash and short-term instruments. Savage noted that while April saw a risk-on tone, Fed caution and global supply pressures limited downside risk for the USD. He also highlighted that potential policy errors from foreign rate hikes were supporting USD resilience, and he did not expect a material change in the Fed's decision [4].
CONCLUSION
The US Dollar strengthened across major pairs as markets braced for the Fed's policy decision amid heightened geopolitical risks and surging oil prices. Central bank caution, persistent inflation concerns, and safe-haven flows supported the Greenback, while commodity-linked and risk-sensitive currencies came under pressure. The market impact is high, with ongoing uncertainty likely to sustain demand for the USD in the near term.
