Oil prices fell for a second session in Asian trade on Tuesday as worries about top energy consumer China and rising oil supply weighed on markets, although possible talks between OPEC and Russia on output cuts offered some support. Russia’s energy minister and Venezuela’s oil minister discussed the possibility of holding joint consultations between OPEC and non-OPEC countries in the near future, the Russian Energy Ministry said on Monday. But Goldman Sachs said it was “highly unlikely” OPEC producers would co-operate with Russia to cut output, while also being self-defeating as stronger prices would bring previously shelved production back to the market. Rising supply also suggests further downside risk to short-term prices. Output from OPEC rose to 33.1 million barrels per day last month as Indonesia’s membership to the group was reactivated,” the note added.
