The new narrative of the US dollar in the era of high oil prices: Traders, don't miss out!

Tonghui Finance APP News—— On Friday, April 3, during the Good Friday holiday, trading volumes in major global financial markets are expected to be significantly reduced, and liquidity conditions remain tight. After the U.S. Dollar Index posted a cumulative gain of more than 2% in March, it is currently hovering and fluctuating near the 100 level. Geopolitical factors have pushed oil prices significantly higher, and ongoing concerns in the market about inflation pressure re-accelerating continue to build. These elements together further increase uncertainty along the Federal Reserve’s policy path. In low-volume conditions, traders should focus on assessing the marginal impact of fundamental signals on exchange rates, rather than relying on short-term price fluctuations.

U.S. Dollar Index’s March Performance and Core Drivers

The U.S. Dollar Index rebounded from near the year-start lows in March, with a cumulative gain of more than 2%, and maintained a high-level consolidation pattern near the 100 mark during the first trading session in early April. This trend was mainly driven by market risk-aversion sentiment dominating trading, as well as renewed concerns about inflation stemming from a sharp rise in oil prices. Traders have observed that the U.S. dollar has shown relatively steady performance against the major currency basket, especially as demand for safe-haven exposure becomes concentrated and released during European and Asian sessions. By contrast, other major currencies face pressure from divergent policy stances among their respective central banks. At current levels, the U.S. Dollar Index has already moved away from the late-2025 trough range, but the sustainability of its upward move is still constrained by the Federal Reserve’s overall cautious tone. Any further rise in oil prices or intensification of geopolitical tensions could reinforce the U.S. dollar’s safe-haven attributes; whereas if risk appetite picks up again, it could trigger profit-taking and cause the index to pull back temporarily.

Transmission from Rising Oil Prices to Inflation Expectations and the U.S. Dollar

Oil prices have been pushed up significantly by geopolitical factors, and market concerns about runaway inflation have become an important support for the U.S. Dollar Index’s strength. Traders generally believe that higher energy prices will quickly transmit through production costs and the consumption chain to the overall price level, thereby affecting the Federal Reserve’s assessment of price stability. The U.S. Dollar Index’s rebound in March unfolded in this context, and the index’s volatility also increased accordingly in early April. Compared with the same period historically, current oil prices have clearly moved away from low-range levels; this not only amplifies global supply-chain pressure, but also provides the U.S. dollar with additional nominal support. Traders need to closely track the structure of the oil futures curve and inventory data to determine whether this transmission will continue to strengthen the U.S. dollar index’s defensive attributes, rather than simply attributing it to a single event shock.

Uncertainty in the Federal Reserve’s Policy Path

This week, Federal Reserve Chair Jerome Powell said there is inherent tension between the two major missions of maximum employment and price stability, and that the current situation calls for a suitable stance of waiting and observing. He emphasized that the current situation is complex and requires more data to confirm the trend. New York Fed President John Williams also said the employment market is sending clear signals, and that a low hiring rate may further intensify economic pessimism. These remarks reinforce market expectations that the Federal Reserve will maintain the current interest-rate range. Based on the latest pricing, the probability that the Federal Reserve policy rate will remain in the 3.5%-3.75% range through end-2026 is about 80%, which has already fallen significantly from the multiple rate-cut expectations at the start of March. Traders need to assess whether oil-driven inflation risks would change this pricing logic: if inflation pressure keeps exceeding expectations, the market may reprice toward a longer period of high interest rates, which would provide additional upward momentum for the U.S. Dollar Index; conversely, if risks gradually ease, it may reduce the U.S. dollar’s relative attractiveness.

Market Dynamics in a Risk-Off Environment

With global markets currently steeped in risk-off sentiment, the U.S. Dollar Index is receiving significant support. Traders noted that ahead of the holiday, safe-haven funds tend to concentrate on allocating to U.S. dollar-denominated assets, leading to strong technical support for the index around the 100 level. Statements from senior Federal Reserve officials further solidify the “data-dependent” framework, so traders are therefore more inclined to wait for confirmation of subsequent inflation and growth signals rather than betting early on a directional breakout. Under this setup, the U.S. Dollar Index may continue to trade in a range near 100 in the short term, but any unexpected change in geopolitical or inflation data could quickly amplify volatility and test the market’s pricing efficiency.
