MOSCOW, Aug 30 (Reuters) - The Russian rouble weakened again in early trade on Wednesday, labouring against a seasonal decrease in the supply of foreign currency after exporters completed rouble purchases to pay their monthly corporate taxes.
Traders say the rouble could face a seasonal shortage of foreign currency supply from exporters in the coming weeks despite informal agreements with the authorities to increase sales of their foreign exchange earnings.
The rouble was 0.6% weaker against the dollar at 96.03 and down 0.6% at 104.24 versus the euro . It shed 0.4% to 13.15 against the yuan .
Brent crude oil, a global benchmark for Russia's main export, was up 0.4% at $85.82 a barrel.
The dollar-denominated RTS stock index was down 0.4% at 1,056 points while the rouble-based MOEX Russian index was 0.2% up at 3,217 points.
