MOSCOW, Aug 28 (Reuters) - The rouble slipped against

the dollar on Thursday, as the Russian currency is set to lose

the fiscal support provided by upcoming month-end tax payments.

At 0730 GMT, the rouble was down 0.12% at 80.25

against the dollar after gaining 0.2% during Wednesday's trade,

according to data compiled by LSEG based on over-the-counter

quotes.

The rouble was 0.11% stronger at 11.22 against China's yuan,

the most traded foreign currency in Russia.

The Russian currency has received support this week ahead of

a single tax payment Russian corporations will make on Thursday,

where exporters usually sell their foreign currency earnings to

meet local liabilities.

Brent crude oil, a global benchmark for Russia's

main export, was down 0.6% at $67.64 per barrel. Falling oil

prices put pressure on the rouble, whose exchange rate largely

depends on foreign currency revenues from Russian oil exports.
