USGC propane values came under pressure in June due to sizeable stock builds linked to falling overseas propane demand (and rising butane), with Chinese buyers reluctant to meaningfully return to US barrels.
However, we have modestly increased our Mont Belvieu price forecast m/m for H2 2025, considering improving US-China trade negotiations and agreements which have cooled relations and allowed NGLs exports to begin slowly picking up once more.
USGC prices will be supported by the ramping up of propane sent outs at ET’s expanded terminal (estimated +125 kbd once it reaches capacity by end-Q3). As such, rising export demand will put a floor of support under ratios to crude as Chinese buying slowly moves back to US barrels through Q3. Nonetheless, we expect USGC propane values to remain below the five-year average on the back of ample field supply growth (y/y) and China’s 11% tariff on US-origin barrels keeping a lid on prices.
For butane, we also amended our USGC forecast modestly higher for H2 2025, mostly due to the recent bullishness in send outs amid the ongoing reshuffling of LPG flows with mixed cargoes more in demand from the US, and Middle Eastern barrels continuing to head to China in greater volumes. However, butane ratios have recently begun correcting lower with US-China trade negotiations progressing, as such we expect butane prices to move back in line with the five-year seasonal average by Q4 as butane export demand slowly wanes m/m through Q3 as flows normalise.
For Europe, more US cargoes aimed at the continent due to Chinese buyers only slowly moving back to US barrels will keep prices in check, especially with local supply lengthening post-North Sea gas plant and refinery maintenance. Dow’s closure of its Olefins No.3 flexi-cracker in June has helped reduce import requirements in NWE, but LPG will remain favoured over naphtha in the region, which will stop prices from falling to the bottom of the five-year range in Q3 and early Q4.
Conversely in the Middle East, conflict in the region and record propane exports to China buoyed values in the region through June, keeping them above the five-year average and year-ago levels.
However, in light of improving US-China relations and rising US export capacity, we have modestly reduced our CP propane forecast for H2 2025, as we expect Chinese buyers to slowly return to US barrels by end-Q3. Moreover, a small uptick in output (+0.5-1%) will add length to the region as OPEC unwinds production cuts and planned refinery outages taper off.
In the Far East, weak Chinese PDH margins and the retrofitting of another cracker (Wanhua No.1 1 mt/year) in June weighed on prices, with Chinese buyers having to pay a premium to secure non-US cargoes in May and June, pressuring petchem demand. Looking ahead, we have modestly increased our Far East propane price forecast through H2 2025. Indeed, Chinese PDH margins have improved on falling crude and rising domestic propylene prices in recent weeks, and margins should find a floor of support from increased US-cargo send outs through Q3 as terminal capacity expands. That said, growing structural length in China’s propylene market this year from alternative technology routes (cracking, FCC, C/MTO plants) will firmly cap PDH runs at around 75% or below going forward, ensuring Far East prices trade below year-ago levels and the five-year average until December.
Meanwhile, we have moderately increased our Far East butane price forecasts for H2 2025, although they remain below year-ago and the five-year average. Indeed, butane prices in Asia have been weighed down by a growing glut in the Chinese market due to limitations in procuring fully laden propane cargoes from the region and therefore having to manage higher volumes of mixed cargoes. However, as we expect trade flows to slowly normalise through Q3, this will lead to the butane glut in China easing and prices moving back in line with the five-year average by November.
