The story this week is less about the Strait of Hormuz and more about what happens to a voyage budget when every cost line reprices at once. War risk alone now runs $10 to $14 million per transit on the charterer’s account: a figure that would have been dismissed as absurd two months ago and is now the starting point for any Gulf loading calculation.
Layer on bunkers above $1,000 per tonne in Singapore, Cape diversions adding $1 to $2 million in fuel, and Gulf port delays stretching to 12 days, and the all-in cost of a voyage has moved so far from its pre-conflict baseline that some trades no longer support the economics at any rate.
Wet Bulk: Records That No One Wanted
The fact that an Aframax fixture at $950,000 per day is even in the conversation tells you where the market is. Confirmed or not, the rumour circulated on Monday without being laughed off, since the underlying dynamics support it. Suezmax and Aframax supply in the US Gulf is at what brokers describe as the tightest ever, with Asian refiners scouring the Atlantic for tonnage that was never designed to serve these routes at this volume.
The displacement from the Gulf (77 VLCCs, or 8.5% of the global fleet, remain trapped behind the Strait according to Kpler) has funnelled into an Atlantic Basin that cannot expand to meet it. VLCC rates on TD3C have held above $400,000 per day for a second straight week. TD22 (US Gulf to China) is unchanged at $22.2 million.
What makes these rates especially hard to manage is the cost that sits on top of them. Five major P&I clubs (Gard, Skuld, NorthStandard, London P&I, and American Club) cancelled war risk cover for the Gulf on March 5. What remains runs at 1 to 3% of hull value, renewed every seven days, with US, UK, and Israeli-linked vessels charged three times more. On a short-haul Gulf voyage, the war risk premium alone can now exceed the freight cost. Insurance has gone from a line item to THE line item.
Bunker economics has compounded the picture. Singapore VLSFO has breached $1,000 per tonne, up $635 since February 28, while Rotterdam sits at $748. That spread (as wide as $300) means route optimisation now starts at the bunker port, not the load port. For a laden VLCC on a 30-day Eastern voyage, the difference between bunkering in Singapore versus Rotterdam can swing the fuel bill by three quarters of a million dollars. Every voyage estimate written before the war needs to be rerun.
The supply side offers no relief. Ukraine struck Russia’s Ust-Luga oil terminal three times in a single week (March 25, 27, and 29), with Ukrainian officials claiming roughly 60% of the terminal’s 700,000 barrel-per-day export capacity has been knocked out. Baltic crude is now tightening on top of the Hormuz disruption: the Atlantic Basin is absorbing redirected demand from two directions at once.
And the grey tonnage pool that might otherwise relieve some pressure is getting murkier, not larger. Russia has begun expanding its dark fleet into LNG, with three 20-year-old carriers sold to a newly formed Turkish entity and reflagged to Sierra Leone, where 93 of 156 vessels broadcasting AIS are under US, EU, or UK sanctions. For charterers, the practical consequence is that more uninspected, uninsured tonnage is entering congested waterways. The risk of a casualty that closes a port or blocks a channel for days is not hypothetical: it is a fixture variable that the market has not yet priced.
Charterer Lens
- War risk at $10 to $14 million per Hormuz transit is now the single largest variable in Gulf voyage economics. Obtain a live quote before every fixture: anything older than 48 hours is stale. For those operating under Western sanctions frameworks, the Cape diversion plus full war risk is the only legal option.
- The Singapore-Rotterdam VLSFO spread has hit $300. At those levels, any eastbound voyage where the additional steaming time to bunker in Rotterdam costs less than $300 per tonne in fuel savings should route through Rotterdam. On a VLCC burning 80 tonnes per day, the breakeven is roughly one extra day of steaming. If the detour is shorter than that, Rotterdam bunkering pays for itself.
- If you are fixing Aframax or Suezmax in the Atlantic, the rate floor has not been found. Evaluate your Q2 spot exposure against available period rates: if the spread between six-month TC and the implied spot forward has widened in your favour, locking in now hedges against a market that has surprised to the upside for five consecutive weeks.
Dry Bulk: The Quiet Cost Squeeze
The BDI held near 2,001 as of March 25, which sounds stable until you look at the components. The Capesize index climbed 2.5% to 2,915, supported by Brazilian iron ore demand on the C3 corridor. Panamaxes moved the other direction, falling 2.6% to 1,796 as available tonnage outpaced cargo demand across the Atlantic. The segment split matters for fixture timing: Capesize rates are firming into Q2, while Panamax charterers have room to wait.
The more consequential story for dry bulk is fertilizer. The Gulf produces roughly a third of global urea exports and 20 to 30% of ammonia (IFPRI estimates). With the Strait effectively closed, urea prices have surged 28% in three weeks, DAP and MAP are above $700 per tonne, and UAN has crossed $400. Iran agreed on March 27 to a UN request allowing humanitarian and fertilizer shipments through Hormuz, but the corridor is narrow: a diplomatic gesture during spring planting season, not a logistical solution for the 2.7 million metric tonnes of fertilizer the US alone imports from Gulf producers annually.
The price transmission is already visible in grain markets. Corn, wheat, and soybeans are up 2 to 7.5% on Hormuz knock-on effects, with soybeans gaining more than seven cents on Monday. China’s grain production forecast for 2026-27 points to corn above 300 million tonnes, which should underpin Panamax demand on the ECSA-to-China corridor through the back half of the year. But fertilizer cost inflation could suppress yields before those cargoes materialise. The comparison to 2022 is instructive: after Russia’s invasion of Ukraine, fertilizer prices took two to four months to peak at 20 to 40% above baseline.
The Hormuz closure is moving faster because a single chokepoint concentrates the supply shock rather than diffusing it across sanctioned trade routes. If nitrogen follows the 2022 pattern but on a compressed timeline, charterers should expect the cargo deferrals to begin hitting fixture desks within weeks, not months.
Charterer Lens
- The Capesize-Panamax divergence is a timing signal. If you need C3 tonnage for Q2, the window to fix at current levels is closing as Brazilian harvest logistics kick in. Panamax charterers, by contrast, have leverage on the spot market that will not last if grain volumes pick up in H2.
- Fertilizer repricing is the dry bulk story to watch. Urea up 28% in three weeks, with the US importing 2.7 million tonnes of fertilizer from Gulf producers annually. If spring planting inputs are deferred, the grain cargo pipeline shifts later in the year: model your Q3-Q4 tonnage needs accordingly.
- On smaller segments, the fuel arithmetic is now decisive. A Handymax burning 32 tonnes per day at Singapore’s $1,000-plus VLSFO spends roughly $32,000 daily on fuel against gross earnings of $16,250: a net loss before you account for port costs, insurance, or crew. The economics only close with fuel-efficient tonnage or Rotterdam bunkering, and owners of thirsty ships know it. Use that as leverage.
The Five-Flag Strait and the Congestion It Creates
Iran now permits transit for vessels flagged to five nations: China, Russia, India, Iraq, and Pakistan. The latest addition, Pakistan’s deal for 20 ships, allows two crossings per day at a reported cost of $2 million each, settled in Chinese yuan. Iran’s parliament is moving to formalise the toll as legislation. Two more Indian LPG carriers carrying 94,000 tonnes transited under naval escort on Monday. Bahrain, separately, has submitted a UN Security Council draft resolution seeking authorisation to use force to protect commercial shipping in the Strait.
The expansion of the approved-flag list has not changed the commercial reality. Hormuz transits remain 95% below pre-conflict levels. The five-flag corridor serves bilateral relationships, not open commerce. And even approved flags face operational uncertainty: two COSCO-linked vessels attempted to exit the Gulf on March 27, broadcast “Chinese owner and crew” on their transponders, and turned back near Iran’s Larak and Qeshm islands before succeeding on a second attempt three days later.
Where the disruption lands hardest is not at the Strait itself but downstream. Khor Fakkan, the UAE’s east-coast transhipment hub, is reporting berthing delays of seven to 12 days. Cargo that cannot exit the Gulf is being rerouted to Indian ports as temporary holding points, with Nhava Sheva alone absorbing roughly 25,000 TEU-equivalents of diverted cargo. Departure delays at Nhava Sheva have risen 118%. The congestion cascade turns a chokepoint problem into a regional logistics problem, and every additional day at anchor generates demurrage exposure that someone will eventually dispute.
Charterer Lens
- The flag of the vessel now determines the cost of a Gulf voyage. Approved-flag tonnage pays a $2 million toll. Western-insured tonnage pays a Cape diversion plus war risk. Factor flag into fixture negotiations from the outset.
- If you have cargo touching Gulf or West India ports, add demurrage buffer to every laytime calculation. Khor Fakkan and Nhava Sheva delays are worsening, not stabilising. Document every event: the disputes on delay attribution are coming.
- The five-flag corridor is a diplomatic arrangement, not a commercial reopening. Every pause in this conflict has been followed by escalation, and four per day is not 125. Structure fixtures with cancellation clauses and laycan flexibility rather than betting on a timeline that no one controls.
What the Voyage P&L Is Actually Telling You
The pattern playing out in LNG captures where every commodity segment is heading. Asian spot has pushed past $20 per MMBtu, opening a $1 to $3 premium over Europe and pulling at least eleven cargoes from European to Asian buyers. Destination optionality, once a contractual nicety, is now being monetised in real time, and the premium flows to whoever holds the flexibility to redirect. That is not an LNG story. It is the story of this market: whoever has options wins, and whoever is locked into a single route, a single flag, or a single bunkering hub pays the full cost of disruption.
Clarksons has warned that a Hormuz reopening could depress tanker rates in the short term, and they are almost certainly right. The tonnage currently stranded behind the Strait will hit the market simultaneously, and spot rates will correct sharply before finding a new floor. But that scenario belongs to the future, and it raises a harder question for any chartering desk planning Q2 and Q3 fixtures today: do you lock in period cover at levels that will look expensive if Hormuz reopens, or do you ride the spot market and accept the risk that it does not?
Chartering desks are negotiating war risk cancellation clauses and force majeure carve-outs that did not exist eight weeks ago. Laytime exceptions for Gulf port congestion are being contested in real time. The standard fixture recap is acquiring new lines and new conditions that will outlast whatever diplomatic outcome emerges from the Strait. The cost of a voyage is one question. The terms under which that voyage is agreed, disputed, and settled are another, and on that front, the industry is still writing the rules.
