Markets on Edge as Iran War Enters Week Five and Energy Risks Escalate

Ultimatums and Escalation Risk
At the center of the uncertainty is a 48-hour ultimatum issued by Donald Trump, demanding Iran reopen the Strait of Hormuz or face strikes on critical infrastructure, including power plants.
Iran’s response has been equally forceful. Officials warned that any further escalation would lead to a prolonged closure of the waterway and retaliatory attacks on US and allied energy infrastructure across the region.
This standoff has significantly raised the risk of a broader regional conflict, with both sides signaling willingness to escalate rather than step back.
A Market Selloff Across Asset Classes
Last week marked a rare and concerning pattern: simultaneous declines across multiple asset classes.
The S&P 500 fell 1.5% on Friday, extending its losing streak to four consecutive weeks. Meanwhile, US Treasury yields surged, with the 10-year climbing to 4.38%, reflecting expectations of tighter monetary policy.
Typically seen as a safe haven, gold also declined sharply, while Bitcoin dropped below $69,000 as investors reduced exposure to risk assets.
This broad-based selloff signals more than just caution. It reflects a repricing of macro risk, particularly around inflation and growth.
Oil and the Inflation Shock
Energy markets remain the primary transmission channel for the crisis. Brent crude closed above $112 per barrel, its highest level in nearly four years, as disruptions in the Strait of Hormuz continue to constrain global supply.
The waterway is responsible for roughly 20% of global oil and liquefied natural gas flows. With traffic effectively halted since late February, the impact is already rippling through gasoline prices, agricultural inputs like fertilizer, and broader supply chains.
Sustained elevated oil prices increase the likelihood of a renewed inflation shock, complicating the outlook for central banks globally.
Central Banks Face a Policy Pivot
Rising energy costs are forcing a reassessment of monetary policy expectations. Markets are increasingly pricing in the possibility that the Federal Reserve may shift back toward rate hikes rather than cuts.
This shift is not isolated to the US. Central banks in Europe, Japan, and the UK are facing similar pressures, as higher energy prices feed into inflation even while economic growth shows signs of slowing.
The combination of rising inflation and weakening growth presents a classic stagflationary risk, one of the most challenging environments for policymakers and investors alike.
Liquidity Concerns and Market Psychology
Beyond fundamentals, market structure is also becoming a concern. As uncertainty rises, investor behavior is shifting from active selling to passive withdrawal.
When buyers step back entirely, liquidity can evaporate. This creates the conditions for sharp, sudden market moves, as even small sell orders can have outsized effects in thin trading environments.
The result is a more fragile market, where volatility can spike quickly and without warning.
Defensive Positioning Takes Hold
Major financial institutions, including Goldman Sachs and Société Générale, have already begun shifting toward more defensive strategies.
This repositioning reflects growing expectations that the conflict may persist longer than initially anticipated, increasing the likelihood of sustained economic disruption.
Investors are moving away from high-risk assets and toward strategies designed to preserve capital in uncertain conditions.
Economic Data Set to Reflect the Impact
The economic consequences of the conflict are expected to begin appearing in incoming data. Early indicators suggest that global business activity is weakening, with purchasing managers’ indices projected to decline.
This would mark the first clear evidence that the conflict is not just affecting markets, but also real economic activity.
Overall
As markets reopen, the key issue is no longer whether volatility will persist, but how severe and prolonged it may become.
The Strait of Hormuz has emerged as the most critical variable in global markets. Its status will influence oil prices, inflation trajectories, central bank decisions, and ultimately, economic growth.
Until there is clarity on energy flows and geopolitical direction, markets are likely to remain unstable, reactive, and highly sensitive to headlines.
NEW ON HORMUZ:
Saudi Pipeline Hits Full Capacity, Stabilizing Global Oil Supply • March 28th, 2026
Saudi Arabia’s East-West pipeline, which bypasses the Strait of Hormuz, is now operating at full capacity of 7 million barrels per day, stabilizing global oil supply amid Middle East tensions. Exports via the Red Sea port of Yanbu reach around 5 million barrels daily, with another 700,000–900,000 barrels of refined products, while 2 million barrels feed domestic refineries. This pipeline has prevented oil prices from spiking despite near-closure of Hormuz, though risks remain from potential Red Sea disruptions by Yemen’s Houthis.
Markets are closely monitoring Yanbu throughput as pipeline stability offsets, but does not eliminate geopolitical risk. Any Red Sea disruption could push crude toward $120 per barrel, strain logistics, and weigh on global growth. Investors and futures prices now reflect a balance between relief from the bypass and caution over emerging conflict, making pipeline throughput the central factor in near-term energy market stability.
Gas Tops $4 as Energy Turmoil Hits the Economy • April 1st, 2026
U.S. gasoline has passed $4 per gallon, diesel $5.45, rising 36 percent since February. The U.S.-Iran conflict and Strait of Hormuz disruptions are tightening supply, while market speculation adds volatility. Consumers and businesses face higher costs, inflation pressures mount, and political sentiment shifts. Globally, rising fuel and shipping prices strain supply chains. If disruptions continue, gas could reach $5–$6, making energy a key driver of economic and market outcomes.
U.S. Doubles Hormuz Reinsurance to $40B Amid Trade Risks • April 3rd, 2026
The United States has expanded maritime reinsurance guarantees to $40 billion through the U.S. International Development Finance Corp., adding major insurers including AIG, Berkshire Hathaway, and Travelers to encourage vessel transit through the Strait of Hormuz. While the program aims to stabilize shipping and ease global trade disruptions amid the Iran conflict, no naval protection is guaranteed, leaving crews and operators cautious. Markets are closely watching participation and vessel activity, as elevated oil and gas prices, supply chain sensitivity, and geopolitical uncertainty continue to drive futures, hedging, and logistical decisions, making Hormuz traffic a critical factor in near-term energy and trade stability.
