US Dollar Strengthens as President Trump’s Tariff Threats Weigh on Global Markets
July 11, 2025 — The US Dollar Index (DXY) has edged higher following renewed tariff threats from President Donald Trump, which have unsettled global trade relations and pressured equity markets. The dollar’s ascent reflects increased demand for safe-haven assets amid rising geopolitical uncertainty and concerns over escalating trade tensions.
Tariff Announcements Trigger Market Volatility
President Trump recently announced a significant increase in tariffs on Canadian goods, setting a 35% levy that surpasses market expectations. This move was justified on the grounds of fentanyl-related concerns but has broader implications as the administration also hinted at sweeping tariff hikes ranging from 15% to 20% on additional trade partners beyond Canada. The announcement has escalated fears of a wider trade conflict, pushing investors toward defensive positioning.
Global stock markets reacted negatively to these developments. The S&P 500 retreated by 0.4% on Friday after reaching a record high the previous day. The Dow Jones Industrial Average lost 222 points, and the Nasdaq Composite slipped 0.3%. The pressure on equities was compounded by tariffs targeting imports such as copper and goods from Brazil, some facing duties as high as 50%. Despite a recent rally fueled by AI optimism in tech stocks like Nvidia, markets cooled off amid tariff-related concerns.
US Dollar Index Technical Overview
From a technical perspective, the DXY rebounded from its July low of 96.377, currently testing resistance around the 97.90 to 98.00 zone. This area aligns with the 50-day simple moving average (SMA) near 98.90, representing a key hurdle for the dollar in the near term. While higher swing highs at 99.421 and 100.540 remain distant targets, the recent pattern of higher daily closes suggests cautious strengthening momentum.
The 200-day SMA, sitting at 103.64, remains well above the current trading range and is unlikely to be breached unless trade tensions accelerate significantly, driving risk aversion further.
Market Participants Watch Fed Policy and Earnings Season
Analysts note that sustaining equity rallies requires alignment between macroeconomic data and Federal Reserve policy signals. Citi strategist Drew Pettit emphasized that this alignment has yet to materialize amid tariff uncertainties. As the US second-quarter earnings season begins next week, investors remain wary of how new tariffs might compress corporate margins and fuel risk-off sentiment.
Should equities continue to weaken, it would likely enhance demand for the US dollar as a safe haven, potentially pushing the DXY beyond the 98.90 resistance toward 99.40. Conversely, oversold conditions in equities could trigger a rebound that may temper further dollar gains unless the Federal Reserve adopts a more dovish stance or trade tensions worsen.
What to Watch Moving Forward
Traders are closely monitoring any additional tariff announcements, particularly those involving the European Union, as well as the market’s reaction during earnings season. These factors will be critical in determining whether the US dollar’s recent strength is sustained or if volatility in equities will moderate, altering risk appetite.
