* U.S. bans imports from Malaysia's Supermax, shares plunge * Malaysia stocks mark worst day in three weeks * Rupiah's long-term prospects supported by equity inflows - analyst By Anushka Trivedi Oct 21(Reuters) - Stocks and the currency of Indonesia, the world's top thermal coal exporter, fell on Thursday as China coal futures plunged amid signs of Beijing's intervention, while Malaysian shares eased 1% after news of U.S. regulatory action on a glove maker. Asian currencies and stocks were broadly weaker, with South Korea's won declining 0.3%, followed by Singapore's dollar and the Thai baht. The mood has been sombre after debt-laden China Evergrande Group's deal to sell a stake in its property services unit fell through this week, reviving concerns about a crisis at the country's high-yield real estate sector.
