MOSCOW, Oct 14 (Reuters) - Trade in China's yuan

proceeded as usual at the Moscow Stock Exchange (MOEX) on

Monday, despite the expiry of a licence from the U.S. Treasury

Department's Office of Foreign Assets Control (OFAC) on Oct. 12

that allowed banks to deal with MOEX.

At 0830 GMT the rouble weakened by 0.13% to 13.48 against

the yuan at the Moscow exchange with the current trade volumes

at 6.6 billion roubles ($68.68 million).

The rouble weakened by 0.32% to 96.10 against the U.S.

dollar at the over-the-counter (OTC) market, according to

LSEG data. The rouble strengthened by 0.7% to 13.45 against yuan

at OTC, according to LSEG data.

The OFAC licence was issued to allow banks to wind down

operations with MOEX after Western sanctions on the exchange and

its clearing agent, the National Clearing Centre, were

introduced on June 12.

The sanctions stopped all trade in dollars and euros at

MOEX, making China's yuan the most traded foreign currency in

Russia. Trade in dollars and euros has shifted to the

over-the-counter (OTC) market, obscuring price data.

Ahead of the licence expiry market participants were

concerned that Chinese banks, which provide liquidity and settle

trade in yuan, may decide to pull out as well for compliance

reasons.

"Some Chinese banks are staying at MOEX, obviously there was

a political decision for them to stay," one forex trader, who

declined to be identified, said.

MOEX does not disclose information about the Chinese banks'

operations. Currently, subsidiaries of Bank of China, ICBC,

China Construction Bank and Agricultural Bank of China are

operating in Russia, according to the central bank.

The Russian central bank's yuan swap facility, through which

the regulator provides short-term yuan liquidity in case of

shortage, was also operating normally with the limits unchanged

from the previous week.

One-day rouble-dollar futures, which trade on the Moscow

exchange and are a guide for OTC market rates, were up 0.48% at

95.1. The central bank's official exchange rate, which it

calculates using OTC data, was set at 96.07 to the dollar.

The rouble weakened by 0.34% to 105.12 against the euro

, LSEG data showed.

Brent crude oil, a global benchmark for Russia's

main export, was down 1.34% to $77.99 a barrel, erasing all

gains made last week.
