Tanker captains transiting the Strait of Hormuz have been commanding monthly fees of up to US$100,000 — roughly A$143,000 — amid separate access restrictions that Iran and the United States have each imposed on the waterway, according to industry insiders and maritime union representatives. Vessels hauling petroleum through the Gulf have encountered repeated boarding and seizure attempts by the naval arm of Iran's Revolutionary Guard at the strait, a pattern that has added strain on regional producers working to maintain viable export corridors.

Vessel attacks intensified around the same period that data pointed to crude shipments approaching their pre-conflict volumes, though analysts cautioned that a direct link between the two developments had not been established. Renewed attention to the waterway came after Iran moved to restrict passage through it at the end of February, a route that carries roughly one-fifth of global oil and gas shipments. Washington's response to the prolonged diplomatic standstill took the form of its own restrictions on Iranian cargo moving through the waterway.

According to a statement from the US Navy-led Joint Maritime Information Center, naval forces have been boarding vessels bound for Iranian ports, while the IRGC has conducted drone overflights and surveillance operations against commercial shipping moving through the strait. Nine tanker attacks within the Strait of Hormuz were logged by the United Kingdom Maritime Trade Operations — known as UKMTO — over the span of a single calendar month. Data gathered by the UN's International Maritime Organization put the death toll among seafarers at a minimum of 24 across 100 verified incidents tied to the conflict.

Advertisements on Facebook have indicated that mariners based in parts of Asia were being recruited for Gulf postings with pay packages reportedly reaching two or three times their standard rates, alongside additional bonuses described as compensation for hazardous conditions and running into the tens of thousands. Financial incentives — reported at around 15 lakh rupees, or roughly $22,000, per month for a ship captain — are drawing crew members to remain aboard vessels and keep navigating the strait, even with the threat of attack hanging over each voyage.

Speaking on a podcast toward the end of September, marine engineer Harshal Singh put the monthly earnings available to workers in the Strait of Hormuz at around one crore rupees, a figure that converts to approximately $143,000. Pay enhancements for captains take effect across two distinct phases of voyage — during passage through the southern Red Sea and Gulf of Oman, and again at each crossing of the Strait of Hormuz — as Indian union representatives have outlined.

Wage packages put on offer to seafarers for Strait of Hormuz transits have reached two to five times standard rates, according to Manoj Yadav, general secretary of the Forward Seamen's Union of India, based in Mumbai — a financial calculation that, for a number of vessel operators, has tipped the balance toward accepting the associated hazards. A Facebook advertisement placed by a vessel management company put before prospective seafarers a pay package combining the standard market rate with a double-pay bonus for assignments aboard crude oil tankers transiting the Strait of Hormuz. A US$1,500 bonus was put on the table by one vessel owner for second and third officers who took up positions with that company in the Gulf.

Sinokor, a commercial shipping operator, was reported to have advertised a bonus equivalent to six months' pay for seafarers completing a return voyage through the area — a round trip understood to last around one month — placing the company among those offering some of the more substantial financial incentives in the sector. Yadav noted that the pay increases and bonuses some vessel owners extended to seafarers had not reached all workers in the sector.

For seafarers based in India, the pay increase represents one factor drawing workers toward these roles. Among the world's leading sources of maritime labour, India stands alongside the Philippines and China, with figures from the External Affairs Ministry putting the number of its nationals aboard commercial vessels in the Persian Gulf at more than 4,500 at present.

Trade unions have raised concerns that seafarers face vulnerability to exploitation and may have limited options when it comes to undertaking work that carries the possibility of fatal consequences. Accounts indicated that certain crew members faced demands to continue voyages against their will, with operators threatening to replace anyone who objected and to bill them for the cost of returning home.

RP Veettil, president of the Sailors Union of India, called on companies to provide hazard pay to crew members assigned to vessels transiting the Hormuz zone — an area he described as carrying warlike conditions — and noted that seafaring work carries inherent occupational risk. He told a prominent news outlet that holding seafarers responsible for their own deaths — on the grounds that they travel voluntarily — was not a defensible position.

Operator willingness to navigate the strait has declined, with daily crossings now running well under the prewar figure of more than 100 vessels. Former Australian naval officer Jennifer Parker told a news channel that crew availability — given the volume of attacks on the route — presents a greater obstacle than insurance cover. Parker noted that crew members from nations with no stake in the conflict were bearing its costs, with seafarers absorbing the burden most directly, in her view.

A growing share of maritime traffic has been threading along the Omani coastline rather than the northern corridor, opting for the more southerly passage through the strait to keep clear of waters where Iranian monitoring applies. Vessels passing through the strait have been documented turning off their GPS transponders and moving under cover of darkness. Firms specialising in maritime intelligence have reported to a prominent broadcaster that some of these covert vessel passages took place with Iranian authorisation, arranged through exchanges at the diplomatic level. A portion of those involved arrived at a different outcome.

Vessel traffic through the Strait of Hormuz was edging back toward prewar levels toward the end of September, according to figures from Kpler. Around mid-August, a statement from President Trump put forward the claim that Navy operations had cleared the Strait of Hormuz of mines, whether through removal or controlled detonation. Naval protection for vessels taking the route near the Omani coastline was extended by the US Navy, with a spokesperson describing the arrangement as one built on multiple overlapping layers of defence.

Parker described a defensive posture involving air cover and combat air patrols positioned above the Strait of Hormuz, with helicopter assets assigned to intercept both drones and ballistic missiles directed at vessels, while unmanned surface craft operated by the United States were also gathering intelligence, surveillance, and reconnaissance data in those waters. Separately, Secretary of State Marco Rubio told reporters that Iran had lost its grip on the strait and that oil volumes moving through it had returned to levels close to those recorded before the conflict.

The IRGC has put forward a contrary position, asserting that oil shipments through the strait have not recovered their earlier pace. Figures from adviser Majid Mirahmadi put October's daily vessel count through the waterway at around 10, down from a pre-war average of roughly 125 per day.
