Japan's base oils exports rose for the first time in six months in June as inventory drawdowns released additional supply for overseas markets
The extra supply arrived alongside elevated South Korean output and rising Chinese exports, adding to downward pressure on regional Group I and Group II prices
The contrast with Europe and the US widened: weaker demand in Asia increased export availability, while tighter supply elsewhere kept those markets comparatively firm
Japan's base oils exports jumped in June as inventory drawdowns and weaker domestic demand freed up more supply for overseas markets.
Domestic demand fell 6% year on year to 144,400 kilolitres (128,000 tonnes) in June, Ministry of Economy, Trade and Industry data showed, marking a second straight monthly decline.
Exports rose 38% year on year over the same month. The increase was the first in six months, with higher shipments to China, Southeast Asia and South Korea.
The shift reflected inventory management rather than weaker underlying demand. Buyers had brought forward more of this year's stock-building into the first quarter, leaving fewer purchases for the second quarter.
Second-quarter demand fell from the first quarter, reversing Japan's usual seasonal pattern of stronger buying after the fiscal year begins in April.
The weaker domestic demand released more barrels for export markets, adding to the downward pressure on regional Group I and Group II prices.
Key Highlights
Total demand, or domestic consumption and exports combined, fell just 1% year on year to 170,700 kilolitres in June, as the export rebound largely offset weaker domestic sales.
First-half domestic demand still rose to 923,000 kilolitres, up 15% from a year earlier, pointing to firm underlying consumption despite the shift in purchase timing.
Quarterly exports remained down 33% year on year, marking a fourth straight quarterly decline despite June's rebound.
Higher June exports coincided with elevated South Korean output and high Chinese supply, adding to regional Group I and Group II availability.
Market Repercussions
Japanese buyers' moves to trim stocks built earlier this year joined a similar trend in other regions, including Europe and the Americas, as the rush to secure supply during the spring disruptions continued to fade.
The similarities ended there.
The additional Japanese barrels arrived alongside elevated South Korean output and rising Chinese exports, boosting Group I and Group II supply across Asia and adding to downward pressure on prices.
Demand also softened in Europe and the Americas, but prices remained firmer because supply stayed comparatively tight.
Lower buying in Asia released additional barrels into the market. In Europe, lower imports kept availability constrained, while in the US, lower production and reduced Group III imports limited any comparable increase in supply.
