Moscow - The MICEX index, Moscow's leading stock exchange, shut down until Friday while trading on the RTS was suspended indefinitely after shares plummeted at opening on Wednesday.
The MICEX's headlong dive, dropping more than 14 per cent in the first half-hour of trading, compounded record losses in the last two days as Russia faces its worst financial crisis since the national default of 1998.
Trading on the MICEX, where most of Russia's stocks are traded, was suspended by market watchdogs at 11:05 am (0805 GMT) for two- days.
