LONDON — Global energy markets are bracing for a fifth consecutive weekly gain as the continued closure of the Strait of Hormuz enters its 21st day. Brent crude surged toward $109 per barrel on Saturday, March 21, 2026, as the maritime blockade severely restricts the flow of approximately 20% of the world’s daily petroleum liquids.
Despite a series of coordinated international policy interventions aimed at stabilizing prices, the persistent physical supply crunch in the Middle East continues to drive bullish sentiment across global exchanges.
Three Weeks of Maritime Gridlock
The Strait of Hormuz has remained effectively impassable for commercial tankers since the escalation of regional hostilities in early March. The impact on global supply chains has reached a critical threshold:
- Stalled Shipments: An estimated 16 million barrels per day of crude and condensate are currently sidelined. Tankers that would normally transit the Persian Gulf are either anchored in the Gulf of Oman or performing costly, multi-week diversions around the Cape of Good Hope.
- Refinery Strain: European and Asian refiners, particularly in Japan and South Korea, are reporting a significant tightening of “sour” crude grades, forcing several facilities to reduce run rates.
- Insurance Premiums: Maritime war risk premiums have remained at historic highs, with most commercial underwriters refusing to cover transit through the “High Risk Area” (HRA) without sovereign military guarantees.
Policy Interventions vs. Physical Reality
International efforts to cool the market have so far provided only temporary psychological relief, failing to offset the loss of Gulf barrels.
- IEA Strategic Releases: The International Energy Agency (IEA) authorized a second emergency release of 60 million barrels earlier this week. While this added liquidity to the market, traders noted that the release covers less than four days of the volume typically lost during a Hormuz closure.
- The U.S.-Japan Accord: Following the White House summit between President Trump and Prime Minister Takaichi, Japan committed to releasing 80 million barrels from its national reserves. While this stabilized the Yen, the physical arrival of these barrels to global markets remains weeks away.
- Monetary Pressures: The sustained high price of oil is fueling renewed inflationary fears. The U.S. Federal Reserve signaled on Friday that if Brent sustains levels above $110 through April, further interest rate hikes may be necessary to combat “energy-pushed” price increases.
Market Outlook: The $115 Threshold
Analysis from Goldman Sachs and Morgan Stanley suggests that if the blockade persists through the end of March, Brent could test the $115–$120 range.
| Benchmark | Price (March 21, 2026) | Weekly Change |
| Brent Crude | $108.84 | +4.2% |
| WTI (West Texas) | $104.12 | +3.8% |
| Natural Gas (TTF) | €52.40 | +11.2% |
The “Tanker Trap” Continues
The International Maritime Organization (IMO) confirmed Saturday that roughly 3,200 vessels remain west of the Strait. Until a “safe corridor” is established by the recently formed six-nation coalition, the logistical backlog is expected to worsen, keeping the “risk premium” firmly embedded in every barrel of oil traded.
