Russian rouble declines further vs dollar on Trump's new Ukraine deadline

MOSCOW, July 29 (Reuters) - Russia's rouble fell further against the dollar and China's yuan on Tuesday, reacting to U.S. President Donald Trump's setting of a new, shorter deadline for Moscow to agree an end to the war in Ukraine.

The rouble was down 1.1% as of 1020 GMT at 82.25 to the dollar, its weakest level since May 12, according to data compiled by LSEG based on over-the-counter quotes.

The rouble has weakened for four consecutive sessions since July 24, losing 4.7% against the dollar. The central bank's 200-basis-point key rate cut to 18% on July 25 - its biggest decrease in over three years - has also contributed to the rouble's fall.

In a sign of his deepening frustration with Russian President Vladimir Putin over the war in Ukraine, Trump said on Monday he was giving Moscow 10 to 12 days to make progress toward ending the conflict or face consequences.

"The current weakening of the rouble is linked to geopolitical factors, and it is challenging to predict how long this trend will persist," said Taras Skvortsov, CFO of Russia's largest lender Sberbank.

Sberbank expects the rouble to weaken to about 90 per dollar towards the end of the year.

Against the Chinese yuan, the most traded foreign currency in Russia, the rouble weakened by 0.8% to 11.43.
