Concerns over regional oversupply have emerged at the end of the peak winter season, writes Efcharis Sgourou
Northwest European butane large cargo prices dropped sharply over the second half of last month as demand weakened at the end of the winter and prompt supply increased. A coaster vessel crash at the Norgal LPG terminal in Le Havre, France — a key import terminal for butane deliveries to two ethylene plants in the country — on 20 March also halted deliveries and may have fuelled supply concerns, although market participants were quick to downplay its impact.
The large cargo assessment declined by more than 22 percentage points to 73.5pc of front-month naphtha swaps over 18-26 March — an eight-month low — while the outright price fell by about a quarter to $511.50/t cif Amsterdam-Rotterdam-Antwerp (ARA) as selling pressure grew. This pressure eased at the end of last month, allowing the outright price to inch back up to $518/t.
Demand for butane was already weak despite ethylene cracker run rates rising this year from lows in 2023. But buying interest waned rapidly in late March as prompt enquiries were covered by a surfeit of US shipments, supported by a wide-open US-Europe arbitrage earlier in the month. About 127,000t of US butane arrived in northwest Europe in March, against 50,000t in February, Kpler data show.
Regional butane demand has dropped after the transition to summer-grade gasoline, which limits the amount of butane that can be blended. Gasoline blenders do not buy large cargo volumes but the decline in sales of coaster and barge cargoes increases regional supply. Northwest European supplies of butane have increased this year as a result of lower natural gas prices, which have fallen by 15pc since January, putting gas at a significant discount to LPG. This has freed up LPG sales from refineries, which had used it in place of gas, as well as improved the upstream extraction of natural gas liquids that were being left in the gas stream.
The first sign of selling pressure surfaced on 21 March when a North Sea producer offered an April cargo at $599.25/t cif ARA, equivalent to 86.5pc of April naphtha, which was about 10 percentage points lower than a public bid for late March delivery the previous week. Offers became more aggressive over the week, reaching the low-70pc range to naphtha by 25 March against no interest. The sellers were able to offload their cargoes behind closed doors over 26-27 March, reportedly in the low to mid-70pc region, alleviating the pressure.
The bearish sentiment was compounded by the coaster incident at Norgal. LPG imports halted afterwards, Kpler ship tracking data show, with cargoes on board the Tristar Shamal, Emily Kosan and Crystal Lavender waiting to discharge late last month. The Tristar Shamal was still waiting offshore on 2 April, the Crystal Lavender was due to unload on 1 April, while the Emily Kosan was diverted to the Dunkirk terminal on 5 April.Butane deliveries to Le Havre serve TotalEnergies' 520,000 t/yr Gonfreville cracker, which has the flexibility to run as much as 80pc butane feedstock, and ExxonMobil's 400,000 t/yr Gravenchon facility, which consumes up to 30pc, according to Argus Consulting.
