KIEV (Reuters) - Ukraine's central bank abruptly reversed a ban that had prohibited most currency trading, less than a day after it was imposed.

The rule, imposed on Wednesday morning, had prohibited banks from buying currency on behalf of their clients, transactions which account for nearly all official currency trade.
