The Central Bank of Russia has issued instructions to exchanges setting parameters for weekend trading to reduce risks for exchanges and their clients. Weekend trading on Saturdays and Sundays is to be treated as additional to Monday trading, rather than as stand-alone sessions, so that clearing and settlement services are not provided on weekends. At the outset, exchanges are expected to set a price corridor with cap and floor values of around 3% relative to securities’ Friday prices. The central bank also advises admitting highly liquid shares to weekend trading to help prevent elevated market volatility. Trading activity, pricing quality and the range of instruments traded will be monitored to assess whether weekend trading can be scaled up and whether additional restrictions are required.
