KONTAN.CO.ID - TAIPEI. Taiwan's central bank said on Sunday it had banned Deutsche Bank from trading Taiwan dollar deliverable and non-deliverable forwards and suspended it for two years from trading forex derivatives as part of a crackdown on speculation.

The Taiwan dollar is at a more than 23-year-high against the U.S. dollar as the island's trade-dependent economy booms on global demand for its tech products as people work from home.

The central bank has been particularly concerned about a case where it said foreign banks helped grain companies engage in currency speculation through deliverable forwards, affecting the stability of Taiwan's foreign exchange market.
