China’s draft plan for a tax on currency trading is getting a cold reception in the foreign-exchange market.

Mizuho Bank Ltd. says the so-called Tobin tax on yuan transactions would reduce liquidity in a currency with bid-ask spreads already five times wider than those of the yen. A levy would set back China’s push to make the yuan a reserve currency and could heighten investor anxiety over capital outflows, according to Commonwealth Bank of Australia. The proposal is “short sighted” and would drive away foreign investors, Citi Private Bank said.
