A summary of trading in key commodities markets overseas:
New York oil prices fell to the lowest level since June on surging US crude stockpiles and the dollar's sharp gains after the eurozone reported worryingly low inflation data.
New York's main contract West Texas Intermediate light sweet crude for delivery in December fell $US1.77 on Friday, closing at $US94.61 a barrel.
In London, Brent North Sea crude for December fell $US2.93 to $US105.91 a barrel.
Traders and investors are still focused on the apparent US glut of crude, with commercial reserves piling up steadily since the beginning of October.
The announcement that Libya will reopen its 110,000 barrels a day Al-Harriga oil terminal also appeared to remove some of the support for Brent.

The most actively traded contract, for December delivery, on Friday settled $US10.50, or 0.8 per cent, lower at $US1,313.20 a troy ounce on the Comex division of the New York Mercantile Exchange.
The US dollar rallied against the euro and other major currencies, drawing strength from the Federal Reserve's upbeat economic outlook, which prompted some investors to worry the central bank may still reduce its stimulus efforts before year end.
Expectations that the European Central Bank (ECB) will cut benchmark interest rates at its coming policy meeting in December pressured the euro lower. Investors anticipate that the ECB will loosen policy in order to ward off the threat of deflation.
