War, oil and the constraint

Published March 26, 2026 Updated March 26, 2026 05:00am

Currency markets appear to have paused, but not without reason. The dollar index has edged higher toward the 99 mark, the euro is holding around USD 1.16, and the yen has weakened modestly toward the 158–159 range.

Price action has narrowed despite a steady stream of conflicting headlines on the Iran war. Is this stability a sign of confidence, or simply a market choosing not to react to signals it no longer fully trusts?

Because the messaging itself has become part of the problem. Washington continues to suggest that negotiations with Iran are progressing, yet Tehran has publicly rejected the existence of any talks. If markets are no longer responding meaningfully to such claims, does that imply they are beginning to discount them? And if so, what does that say about the reliability of policy signalling at a time when energy markets are being driven as much by rhetoric as by physical supply?

Oil remains the central variable. Brent has surged from roughly the mid-USD70s before the conflict to almost USD 120 at its peak, before pulling back toward the mid-USD90s, still leaving it more than 25–30 percent higher than pre-war levels. The speed of that move, combined with sharp intraday swings, points to elevated volatility and thinning liquidity, where pricing is being driven as much by headlines around Hormuz and policy signals as by underlying supply-demand fundamentals. How do traders price a supply route that may function one day and falter the next? And how long can markets rely on headline-driven adjustments before that uncertainty becomes embedded in risk premiums?

Recent trading behaviour raises further questions. Large positions were placed in crude futures minutes before a presidential statement that triggered a sharp selloff. Prices dropped as much as 15 percent within minutes. Was that anticipation, coincidence, or something more problematic? Markets are accustomed to reacting to information; they are less comfortable when the timing of that information itself becomes tradable. At what point does volatility stop reflecting risk and start reflecting signalling?

That distinction matters because the economic consequences are already visible. Fuel prices in the United States have risen materially since the conflict began, feeding directly into consumer costs. Political approval has weakened alongside them. If higher oil prices are now a domestic political constraint, how sustainable is a strategy that risks pushing them higher? And can messaging around negotiations realistically offset the inflationary impulse coming from energy markets?

There is also an external dimension that is becoming harder to ignore. Allies have shown limited appetite for deeper involvement, even as they absorb the economic fallout. Europe faces renewed energy pressure. Asian importers remain exposed to Gulf supply routes. If the burden is being shared globally, to what extent are the decisions shaping that burden being coordinated? How long can others continue managing the consequences of a policy they did not choose?

The longer the conflict persists, the more it intersects with the structure of the global financial system. For decades, Gulf energy flows, dollar pricing and US security guarantees have formed a reinforcing framework. That arrangement has supported both energy stability and the dollar’s central role in global finance. But if the security component is perceived to be less reliable, does that begin to alter incentives over time?

There are early signs of gradual change. A larger share of Middle Eastern oil is moving toward Asia. Some transactions are being explored outside the dollar, even if only at the margins. Sovereign investors in the region continue to hold substantial dollar assets, but the question is whether those allocations remain as unquestioned as before. Does a prolonged conflict accelerate diversification, or does the system absorb another shock without structural change? And let’s not forget the added, obvious dynamic of the US not coming to, or even being able to, support Gulf allies when they are attacked.

Currency markets, for now, seem to be reserving judgment. That restraint may itself be the signal. Rather than reacting to each headline, traders appear to be waiting for something more definitive. But what would constitute clarity in this environment? A ceasefire that holds? A sustained reopening of shipping routes? Or simply a period in which policy signals and observable reality begin to align more closely?

Central banks are facing a similar dilemma. Higher oil prices complicate the inflation outlook, even if the transmission is uneven. Policymakers had been preparing to discuss the pace of easing; now they are being forced to reconsider the persistence of price pressures. How long can that reassessment be delayed if energy costs remain elevated? And how much flexibility remains if growth begins to soften at the same time?

All of this leaves markets in an unusual position. The immediate reaction function has slowed, but the underlying uncertainties have not. Oil, policy signalling and political constraints are now feeding into each other in ways that are becoming harder to separate.

Which brings the focus back to that initial calm. If the dollar is firming, the euro holding, and the yen weakening despite rising geopolitical risk, what exactly is being priced in? And more importantly, what is being ignored?

Because the real tension may not sit in the market at all, but in Washington. The same war that is meant to project strength is also pushing up the one price that matters most politically. Oil does not distinguish between geopolitical objectives and domestic approval ratings. It feeds directly into the cost of living, and voters tend to notice.

That leaves Trump with a narrowing set of choices. Escalation risks keeping energy prices elevated. De-escalation risks undermining the narrative of control. And attempts to manage the market through signalling are now being tested in real time, not just by adversaries, but by traders.

Markets may still be pausing. But the constraint is already visible. If oil continues to dictate the terms, the question is no longer how the war ends, but whether it can be pursued without destabilising the very economy it was supposedly meant to protect.
