In thIS paper, BEKK-GARCH model is used to empirically test the volatility spillover effects among domestic RMB spot and forward foreign exchange markets, offshore RMB foreign exchange markets in Hong Kong and RMB NDF markets under different exchange rate term structures, and IS model and PT model are used to examine the price discovery power among the four markets and rank them. It is found that the pricing power of RMB exchange rate tends to shift to the offshore market in Hong Kong, and accordingly, the offshore RMB foreign exchange market in Hong Kong has the strongest price discovery power.
