Lack of authorised hedging tools leaves mainland banks vulnerable to rate shocks
New rules allowing domestic and foreign banks to trade a broad range of derivatives in China should allow investors more tools to manage risk stemming from huge government bond holdings.
The move will also potentially prepare the way for a liberalisation of the closed capital account.
The resumption of authorised derivatives trading - largely halted after a bond trading scandal in 1995 - was unveiled by the China Banking Regulatory Commission (CBRC) on Sunday with new rules which allow qualifying foreign banks to participate.
Banks' need to better manage financial risk stems in large part from a maturity mismatch between short-dated bank deposits and longer dated government bonds which represent about 15 per cent of bank assets.
China Merchants Bank bond trader Yin Jinhua said: 'The need for hedging products is crucial because bond holders need to buy options to hedge against a potential rise in interest rates.'
