High European supply of LPG and weak heating demand could hinder the typical seasonal rally for coaster vessel prices in 2024.
Freight rates for 1,800-5,000t coasters tend to follow a clear seasonal trend. Rates start rising in December or January and continue pushing higher until around May before a rapid decline. Between 2022 and 2023, the Argus 1,800t Tees to ARA rate rose from $48/t on 12 December to $75/t on 26 May, before plummeting back down to $42.50/t by 25 July.
Additional heating requirements in winter boosts demand for LPG in Europe and north Africa, which supports higher rates for coasters because they are often used to transport cargoes for prompt top-ups of LPG during unforeseen shortages or to take advantage of brief intra-European arbitrages. During the busier winter period in the LPG market, charterers secure more coasters in Contract of Affreightment (COA) agreements, to deal with higher flows and avoid spot price volatility. Many trader 're-lets' come off the spot market so firms can use them for their own requirements. This compels charterers to compete over fewer available vessels — pushing up rates.
This trend could be hampered in 2024 as key drivers of European LPG demand falter while supply is high. LPG requirement for the heating market has been minimal in 2023 and inventories are high. The petrochemical industry, a key consumer, is likely to maintain lower run rates at propane dehydrogenation (PDH) plants because of weak olefin margins, weighing on the need for LPG as a feedstock.
US LPG over here
While demand wanes, LPG stocks are likely to remain high, in part because of the high amount that will probably continue to be imported from the US.
Very Large Gas Carrier (VLGC) voyages through the Panama Canal dropped in 2023 because of low water levels, and are slated to fall further in January and February. This has driven up US exports to northwest Europe and into the Mediterranean, because voyages from the US to east Asia avoiding the Panama Canal take around two weeks longer and have sometimes proven unfeasible.
LPG imports to northwest Europe hit 698,000t in November, the second highest on record, with 92pc coming from the US, according to Argus data. US imports have produced an LPG oversupply that depressed regional prices and rendered the Tees, UK, to Mohammedia, Morocco, trade virtually inactive in the fourth quarter of 2023.
These trends are likely to continue well into 2024, reducing demand for coaster vessels as higher supply and lower prices suppress the need for small top ups, and this could dampen the seasonal rise in freight rates. The size of the small coaster fleet is projected to remain broadly the same, while a weak petrochemical market could push more vessels into LPG deliveries, further pressuring rates.
ETS uncertainty
One uncertainty in the market is the EU's extension of its emissions trading system (EU ETS) to maritime emissions from 1 January.
The ETS is designed to decrease CO2 emissions by requiring businesses to purchase EU Allowances (EUA). Owners of cargo and passenger ships above 5,000 gross tonnes travelling to, from or between EU ports will be required to pay for 40pc of their emissions. Many owners have indicated they will pass the costs on to charterers, yet the industry standards for this cost remain unclear.
Small coasters will not be counted under the regulation as they are below the tonnage threshold, which could give them a competitive edge and provide a modest lift in demand.
