What caused the sharp selloff in PetroChina and other Hong Kong listed energy stocks, and how did the combined factors of the Iran Israel ceasefire, Saudi Aramco's largest monthly price cut for Asian buyers since 2022, broader Asian market weakness, and OPEC+'s production increas

Saudi Aramco's largest price cut to Asia since 2022. On June 8, Aramco slashed the official selling price (OSP) for Arab Light crude to Asian buyers by $6/barrel for July shipments — the deepest single-month reduction since 2022 — cutting the premium to $9.50/bbl over the Dubai/Oman benchmark . This was a direct signal that demand in Asia, the kingdom's largest market, was softening .

OPEC+ production increase. On June 7, seven OPEC+ nations (led by Saudi Arabia and Russia) agreed to raise output quotas by another 188,000 barrels per day in July, marking the fourth consecutive monthly increase . The cumulative unwinding of voluntary cuts now totals roughly 788,000 bpd, reinforcing a supply-growth narrative .

Broader Asian market weakness and China demand concerns. Chinese crude imports have declined sharply, acting as a key drag preventing oil from holding above $100 . A broader risk-off tone in Asian equities also pressured the sector, with tech stocks and geopolitical uncertainty weighing on sentiment .

Combined effect on crude prices. Brent crude fell from war-driven highs above $107/barrel in early April to hover around $92/barrel by June 9 . The ceasefire removed the immediate supply-disruption premium, Saudi's price cut confirmed weak Asian demand, and OPEC+'s steady quota increases signaled that the alliance sees no need to constrain supply — together collapsing the risk premium that had inflated prices during the conflict.
