Freight rates for the Jones Act fleet of US-built and crewed vessels that transport oil and other liquids between US ports have responded little to US government shakeups in 2025.
The rate for a Houston, Texas-Port Everglades, Florida voyage on a Jones Act medium range (MR) tanker dropped by 8¢/bl to $3.29/bl between 3 January and 30 May per Argus assessments, down by only 2.3pc in that time despite US president Donald Trump's February announcement to bolster US shipbuilding.
Trump has expressed a desire to boost US shipbuilding, while shorter-term remedies to an aging US-flagged fleet could come in the form of converting foreign-flagged vessels rather than building new ships domestically. The cost to build an MR tanker at a US shipyard is about $210mn,compared with $50mn to build the same vessel in South Korea, according to Macquarie Bank.
Vessels re-flagged in the US are eligible for US government contracts, such as Military Sealift Command loadings, alongside other support programs extended by the US to vessels flying its flag. But they do not meet all the requirements to join the Jones Act fleet shipping between US ports, specifically the US-built requirement.
A lack of newbuilding activity has helped keep $/d rates elevated for the less than 50 Jones Act MR tankers that are typically under multi-year time charter contracts.
Jones Act $/d rates have remained rangebound since the start of the year between $86,000/d and $91,000/d per Argus assessments, an order of magnitude higher than the $8,952/d averaged by internationally flagged MR tankers carrying refined products like diesel from the US Gulf coast to Pozos, Colombia in the same period.
Most of the downward pressure on Jones Act rates in 2025 likely came from declining crude prices amid roiling market uncertainty surrounding on-again and off-again US tariffs.
The response from shippers involved with the Jones Act fleet has been "more skepticism rather than optimism" and there had not been "any serious reaction by the market to the administrative initiatives", according to a Jones Act shipowner.
"There has been a push to ease the re-flagging of foreign built vessels into the US flag fleet, but of course these will not be Jones Act vessels and their introduction to US flag does not benefit the domestic shipyards which is the co-ultimate target, that and labor," the contact told Argus. "The shortage of US mariners is, of course, another important issue as well that will have to be wrestled with."
