The Iran–U.S.–Israel War May Be Over. Its Financial Regime Is Not.

The market narrative has shifted from war escalation to post-ceasefire normalisation. That shift is understandable—but premature.

 

The June 17 U.S.–Iran memorandum committed both sides to cease hostilities and reopen the Strait of Hormuz. Yet renewed military exchanges and tanker-related incidents in late June showed that this is not a durable-peace environment. It is a fragile post-conflict risk regime.

 

1. Oil prices are normalising. Energy logistics are not.

 

At the height of the shock, the IEA described the disruption as the largest supply disruption in the history of the global oil market. Gulf production curtailments, damaged infrastructure and the near-halt of tanker traffic through Hormuz pushed Brent close to USD 120/bbl.

By late June, Brent had returned to roughly USD 73–74/bbl—close to pre-war levels—as exports gradually resumed and supply fears eased. However, this does not mean that the system has returned to normal. Cargo throughput through Hormuz is still running at around half of pre-conflict crude levels, while war-risk insurance costs and route uncertainty remain elevated.

The key distinction is simple:

Oil prices are pricing recovery. Shipping markets are still pricing risk.

 

2. Global equities moved quickly into “risk-on” mode—but not only because of the ceasefire.

 

Financial markets have largely looked through the geopolitical shock. During Q2 2026, the MSCI All-World Index rose almost 14%, the S&P 500 gained 14%, the Nasdaq advanced 20%, and Europe’s STOXX 600 was on course for a 10% quarterly gain.

 

However, attributing this rally solely to de-escalation would be misleading. The rebound has also been powered by AI-related investment, resilient corporate earnings and a stronger-than-expected U.S. economy.

The ceasefire removed part of the energy supply tail risk. It did not remove the broader risk premium attached to inflation, freight, insurance, financing and regional instability.

 

3. The U.S. dollar became the clearest second-order winner.

 

On the day of the U.S.–Iran agreement, the dollar initially weakened as oil prices and Treasury yields declined, while the euro briefly strengthened.

 

But the quarterly picture is very different. The dollar gained 1.4% against a basket of major currencies in Q2, while the Japanese yen weakened to around JPY 162.23 per USD—its weakest level in four decades.

 

Why?

Because the conflict did not only create a safe-haven shock. It also created an inflation shock. Higher energy prices contributed to expectations that the Federal Reserve may need to keep policy tighter for longer—or even raise rates.

For companies operating across multiple jurisdictions, this matters more than the political headline:

USD-denominated costs can rise even after oil falls.

Emerging-market currencies remain exposed to capital outflows and higher funding costs.

 

Energy-importing economies face renewed inflation and balance-of-payments pressure.

 

4. Gold did not behave like a simple “war hedge”.

 

Gold has been one of the most counterintuitive parts of the post-war market story.

Spot gold was trading around USD 4,026/oz on June 30, after falling 11.2% during June and heading for its largest quarterly decline since 2013.

This illustrates an important market lesson:

Gold is not only a geopolitical hedge. It is also highly sensitive to real yields, the U.S. dollar and monetary-policy expectations.

As ceasefire optimism reduced immediate safe-haven demand, the stronger dollar and expectations of tighter U.S. policy increased the opportunity cost of holding non-yielding bullion.

 

5. The regional impact remains far more uneven than the global equity rebound suggests.

 

The IMF’s April reference scenario projected MENAP growth at only 1.4% in 2026, a 2.3 percentage-point downgrade from its October 2025 forecast. For Gulf oil exporters directly affected by the conflict, projected growth revisions reached as much as 15 percentage points, with five of eight economies expected to contract under that scenario.

Regional equity markets have also remained sensitive to renewed escalation. On June 28, Saudi Arabia’s TASI fell 0.2%, Qatar’s market edged up 0.1%, while Egypt’s EGX30 dropped 2.1%.

 

Asia remains particularly exposed. The IMF estimates that retail gasoline prices in emerging Asian economies had increased by around 40% since the war began, while currency depreciation, capital outflows and higher bond yields amplified the shock.

 

What should cross-border businesses monitor now?

Not only ceasefire headlines.

 

Watch:

 

Actual Hormuz cargo volumes—not just tanker movements;

War-risk insurance and freight costs;

Brent’s forward curve;

USD strength and emerging-market FX pressure;

Inflation expectations and central-bank repricing;

 

The pass-through into wages, mobility costs, payroll budgets and supplier contracts.

For employers, investors and cross-border operators, the war may be moving out of the headlines. But its effects are still moving through energy costs, FX markets, financing conditions and workforce budgets.

 

The conflict may be quieter. The financial aftershock is not.
