Oil markets are increasingly split between paper trading and physical supply dynamics as tightening inventories put pressure on availability.

With ceasefire talks postponed for the second time in a week, tensions between the U.S. and Iran over the Strait of Hormuz remain unresolved. Although equity markets have rebounded this month—shifting focus to a more optimistic macro backdrop—and crude futures have retreated from their March peaks, investors may be underestimating the tightening in physical oil supply.

At the start of 2026, an oversupply of crude was expected to weigh on prices. However, damage to energy infrastructure and production cuts in the Middle East have heightened concerns about a supply crunch triggered by disruptions in the Strait of Hormuz. Typically, about one-fifth of global oil supply flows through this passage, yet since March 1, only around 23,000 kilobarrels have exited—equivalent to less than a day and a half of normal volumes based on the previous year’s average. While earlier oversupply has cushioned the initial impact, a full market rebalancing could take several months.

Much of the attention has been on futures prices in the “paper” market, but a growing disconnect with the physical market has gone largely unnoticed since mid-March. Signs of tightening supply are evident as futures continue to trade below dated Brent—the benchmark for physical oil—even as prices recover after briefly surging past $140 per barrel ahead of the U.S.–Iran ceasefire.

As the last shipments that left the Strait of Hormuz before the conflict only reached their destinations in the week of April 13, securing physical crude supplies is quickly becoming a top priority. Japanese refiners have increased purchases of U.S. oil, Chinese buyers have pushed imports from Vancouver to record levels, and India has ramped up acquisitions of Venezuelan crude. In some cases, traders at Asian refineries have reportedly been willing to pay almost any price to secure cargoes.

While oil futures could decline once credible news emerges of a sustained reopening of the Strait, the shape of the futures curve indicates that a higher price floor may now be in place. Ongoing tightness in the physical market could drive a longer-term shift in the energy landscape—from a just-in-time supply model toward one that places greater emphasis on holding strategic inventories.

What’s Driving the Buzz Around the Petrodollar?

A major theme tied to the recent squeeze in physical oil markets is renewed speculation about the “death” of the petrodollar. Still, that narrative appears overstated. The petrodollar system—rooted in a 1970s agreement between the U.S. and Saudi Arabia to price oil in dollars and recycle those revenues into U.S. assets—remains structurally intact.

Concerns were stirred when Iran reportedly accepted transit payments in Chinese yuan, fueling talk of a potential shift toward a “petroyuan.” However, such a transition would be gradual at best, unfolding over years or even decades—not in a matter of weeks. That said, the offshore petrodollar system may be less influential in the current shock compared to past cycles.

Several factors explain this shift. Gulf nations have increasingly diversified away from traditional reserve assets like U.S. Treasuries, favoring sovereign wealth funds and equity investments instead. Saudi Arabia, for example, has begun issuing dollar-denominated bonds rather than simply reinvesting in them. Additionally, the temporary decline in Middle Eastern oil flows due to disruptions in the Strait of Hormuz has reduced the scale of dollar recycling tied to energy exports.

At the same time, the U.S.’s position as a net energy exporter helps sustain strong dollar liquidity within North American oil markets, reinforcing the broader role of the dollar in global energy trade.

What About Equities?

As global markets have shown since late February, rising oil prices don’t impact all regions equally. The U.S., now firmly a net exporter of petroleum products, enjoys a degree of insulation. This status helps shield domestic equities, which also tend to rely less on overseas revenue than many international peers—reducing vulnerability to global spillovers.

In contrast, developed markets outside the U.S. appear more exposed. Europe’s relative underperformance during the conflict highlights how higher energy and raw material costs can squeeze corporate margins and cap earnings growth. At the same time, rising oil prices often translate into “imported” inflation, pushing expectations higher for rate hikes from central banks like the European Central Bank and the Bank of England this summer. Even if markets treat the shock as temporary, tighter monetary policy could weigh on European equities in the near term.

Japan is particularly sensitive, with roughly 88% of its oil imports coming from the Middle East. Still, Japanese stocks have shown some resilience, supported by a rebound in technology shares. A similar pattern is visible across emerging Asia: markets with strong tech sectors, such as South Korea and Taiwan, have held up better, while countries like Thailand and Indonesia—less driven by tech—have been more negatively affected by rising oil prices and supply constraints.

Conclusion

This unprecedented shock to global energy supply is something investors should keep a close eye on. Current market signals point to oil prices staying elevated, while tightness in the physical market could persist as supply takes time to normalize—potentially marking a more structural shift in how energy markets operate.

That said, the situation does not appear catastrophic for either the U.S. dollar or global equities. The dollar index has actually strengthened since the conflict began, reinforcing its role as the world’s primary reserve currency. Similarly, concerns about the collapse of the petrodollar system seem exaggerated.

With both Washington and Tehran signaling a willingness to maintain the temporary ceasefire and continue negotiations over the Strait of Hormuz, equity markets are likely to shift their focus back to underlying fundamentals. The disruption from the effective closure of the waterway may remain a background factor rather than a dominant driver.

In the near term, U.S. equities are expected to outperform both developed and emerging markets, as strong earnings—particularly from the technology sector—should more than offset the relatively limited drag from higher oil prices.
