Rouble hits more than one-week low against dollar before Putin-Trump talks

Aug 15 (Reuters) - Russia's rouble hit a more than one-week low against the dollar on Friday, with all eyes on talks later in the day between the leaders of Russia and the United States that investors hope could bring Moscow and Kyiv closer to a ceasefire.

Russian markets have been jittery since U.S. President Donald Trump set an August 8 deadline for Russia to agree to peace in Ukraine or face tightened sanctions.

At 0807 GMT, the rouble was down 0.3% at 80.00 to the dollar, according to data compiled by LSEG based on over-the-counter quotes. Earlier in the session, it reached 80.2955, its weakest mark since August 6.

The rouble was 0.4% weaker at 11.09 against China's yuan, the most traded foreign currency in Russia.

The rouble has lost support of some capital controls after the government on Thursday abolished a requirement for exporters to repatriate and sell part of their foreign currency earnings.

This change should not affect FX supply or the rouble rate too much, Bogdan Zvarich of Promsvyazbank said in a note.

"Investors are now more focused on geopolitical factors," Zvarich said. "We expect a moderate decline of the rouble at the start of next week."

The rouble has also been held back by low oil prices, reduced government FX interventions this month and declining export revenues.

Brent crude oil LCOc1, a global benchmark for Russia's main export, was up 0.6% on the day at $66.42 a barrel.
