The rouble bounced back from more than three-week lows against the dollar and euro in Moscow trade on Monday, supported by strong fundamentals while buffeted by lower oil prices and the end of a favourable month-end tax period.
By 1418 GMT, the rouble was 2 per cent stronger against the dollar at 60.42, having earlier touched 62.4875, its weakest point since July 7. It had gained 1.1 per cent to trade at 61.78 versus the euro, reports Reuters.
Analysts noted that the Russian currency retains strong fundamentals. "Demand for foreign currencies from importers and the population is not outweighing supply from exporters," said Banki.ru analyst Bogdan Zvarich.
High oil prices and a strong current account surplus stemmed some losses last week, but the rouble still lost around 7 per cent to the greenback.
"The rouble weakened steadily due to the end of the tax and dividend period," said Dmitry Polevoy, head of investment at Locko Invest.
The tax payment period that usually sees exporting firms convert foreign currency revenues to pay local liabilities ended last week.
The central bank's decision to cut its key rate to 8 per cent last month and a hint at further possible cuts also reduced the upside pressure on the rouble.
Polevoy said it was quite possible that the rouble could soon weaken temporarily to 63-65 against the dollar.
A trader at a major Russian bank said the rouble's swings on Monday were linked to speculation that the central bank was studying the likelihood of sanctions being imposed against the Moscow Exchange and the halt in exchange trading in the dollar and euro that would cause.
The first reaction to such speculation is to buy foreign currency but demand for forex related to this faded in the afternoon, the trader said.
The central bank said on Friday it was modelling various sanctions scenarios with forex market participants after Forbes Russia had earlier reported that the central bank was discussing a mechanism for managing the rouble-dollar exchange rate should exchange trading be halted in the event of sanctions against the Moscow Exchange and the National Clearing Centre.
The market is also anticipating news that the government will soon tweak and reinstate Russia's budget rule that diverts excess oil revenues into its rainy-day fund with a new cut-off price.
The rouble is the world's strongest-performing currency so far this year, boosted by measures to shield Russia's financial system from Western sanctions imposed after Moscow sent troops into Ukraine on Feb. 24.
These include restrictions on Russian households withdrawing foreign currency savings. The central bank extended restrictions on forex cash withdrawals by six months on Monday, in an expected move.
Russian stock indexes were mixed. The dollar-denominated RTS index was up 1.4 per cent to 1,144.8 points, while the rouble-based MOEX Russian index was 0.9 per cent lower at 2,194.8 points.
