An Unusual Relationship: When the Dollar Trades With Oil

FXCM's USDOLLAR basket is being pulled in several directions at once, and it is not behaving in the way it usually does. Instead of being driven mainly by interest rates or growth expectations, it has become much more sensitive to oil prices and geopolitical developments. Currently, it is moving in response to shifting headlines, particularly those tied to the Middle East and energy markets.

A big part of this story is how closely the dollar is moving with oil. The correlation between the two has climbed to unusually high levels, meaning they are often rising and falling together. That is a break from the typical pattern, where a stronger dollar would normally weigh on oil. Right now, both are being driven by the same underlying force: geopolitical risk, especially concerns around supply disruptions in the Strait of Hormuz.

Geopolitics Driving Inflation and Rate Expectations

As tensions between the US and Iran have intensified, oil prices have pushed higher, at times moving above $100. That has fed into inflation concerns, as higher energy costs ripple through the broader economy. In turn, bond yields have moved up, and expectations for Federal Reserve rate cuts have been pushed further out. This backdrop has given the dollar some support, not just because it is seen as a safe haven, but also because higher inflation tends to keep interest rates elevated.

That said, the dollar's strength has not been particularly convincing. It has tended to firm when tensions rise, but those gains have often faded just as quickly when there are signs of progress or de-escalation. The market is reacting to the news flow rather than committing to a clear direction. When the geopolitical picture worsens, the dollar catches a bid. When things calm down, that support fades.

This has created a market that feels more two-way than directional. The dollar is not simply rising because oil is rising. Both are responding to the same events, but in different ways. Oil is reacting directly to supply risks, while the dollar is also influenced by investor sentiment, growth expectations, and rate pricing. As a result, they can move together for a time, then quickly diverge when the narrative shifts.

A Two-Way Market With No Clear Anchor

Another layer to this is how different economies are affected by higher oil prices. The US, as a major energy producer, is better insulated than regions like Europe or Japan, which rely more heavily on imports. That has helped support the dollar against currencies in those regions. At the same time, commodity-linked currencies have also found some support, reflecting the broader influence of resource prices on FX markets right now.

Monetary policy is still important, but it is not leading the story. Instead, it is reacting to what is happening in oil. The Federal Reserve is effectively on hold, with markets scaling back expectations for rate cuts because inflation risks remain elevated. As long as oil stays high, that pressure on inflation is unlikely to ease, which keeps the Fed cautious. But if oil prices fall, the picture could change quickly, and rate cuts could come back into focus later in the year.

This uncertainty explains why the dollar has struggled to build momentum. Markets are not fully convinced that the conflict will escalate, but they are also not confident it will be resolved quickly. Instead, they are moving between these two possibilities, adjusting positions as the outlook shifts. That is why currency moves have been relatively measured, even when oil has been volatile.

Stepping back, this period highlights a broader shift in how currencies are trading. Domestic fundamentals have taken a back seat, at least for now, with global factors like energy supply and geopolitics playing a much bigger role. Oil has effectively become the link between these forces, influencing inflation, interest rates, and relative economic performance all at once.

Looking ahead, the path for the dollar depends heavily on how the current situation unfolds. If tensions escalate and oil continues to climb, the dollar is likely to strengthen further. If there is a meaningful de-escalation and oil prices ease, the opposite is likely, with the dollar coming under pressure as inflation concerns fade and rate cut expectations return.

For now, the key point is simple. The dollar is being driven by oil and geopolitics, but without a clear, lasting trend. It is not decisively strong or weak. It is reacting, adjusting, and waiting for a clearer direction to emerge.
