Flow Analysis: The Strait of Hormuz Ceasefire's Price Impact

The two-week ceasefire has enabled a partial, fragile flow through the Strait. A total of 21 vessels transited over the weekend, a noticeable uptick from the near-trickle since the conflict began. Yet this volume remains a fraction of the prewar average, with analysts noting traffic is substantially far below normal levels.

Oil markets have barely reacted to the news, with prices showing only modest gains. This tepid response reflects deep skepticism about the deal's durability, with analysts citing expectations of a last-minute postponement. The flow itself is highly selective, dominated by outbound traffic as permits are primarily granted for vessels to exit the Arabian Gulf.

Many ships remain stalled or moving cautiously, with a massive backlog of thousands of vessels waiting in adjacent waters. The flow is not a return to normal but a cautious, negotiated trickle, with alternative routes like the Omani corridor seeing minimal daily traffic.

The Liquidity Constraint: Vessel Concentration

The ceasefire's fragile flow is constrained by a massive, pre-existing backlog. By mid-March, more than 1,000 merchant vessels remained positioned west of the Strait, creating a severe liquidity constraint on global shipping. This concentration reflects a system under pressure, with complex operating conditions across all major segments from dry bulk to tankers.

The backlog is not a uniform stockpile. Dry bulk vessels show a clear imbalance, with outbound movements far exceeding inbound traffic as operators prioritize exits. Tankers, representing one of the most heavily exposed segments, are dominated by laden vessels awaiting passage, yet movements remain highly selective. This selective continuity is complicated by the active Iranian 'Ghost Fleet,' which continues to load cargo and transit the Strait, funding the conflict and further muddying the flow picture.

The result is a market where physical supply is trapped and visibility is poor. With a system already strained by a sharp contraction in vessel movements and widespread AIS signal irregularities, the partial reopening offers only a narrow, negotiated channel. The backlog of over a thousand vessels represents a significant, unresolved liquidity overhang that will limit the pace of any true normalization.

Catalysts and Price Scenarios

The primary catalyst is the two-week ceasefire's expiration. The deal's fragile nature is underscored by Iran's own statement that it does not signify the termination of the war and that its forces remain ready to strike. With the White House deadline having passed, the market now watches for the next move. A collapse of the truce would likely trigger a sharp spike in oil prices as supply fears return.

A secondary variable is the viability of the Omani corridor. This alternative route has seen consistent, albeit small, daily traffic since early April, offering a potential buffer. However, current traffic is a minimal fraction of normal levels and dominated by outbound vessels, limiting its immediate impact on global supply.

If flow stabilizes, the price impact could be significant. The partial reopening has already prompted some market relief, with oil prices dropping. One projection suggests prices could fall toward prewar levels, with a potential $20/barrel drop. This scenario depends on the ceasefire holding and the backlog of over a thousand vessels being cleared, a process that will take time.
