I would like to short USD/CNY (ie, long RMB) at Oanda. But I am curious about how much interest rate I need to pay. http://fxtrade.oanda.com/tools/statistical_information/oanda_interest_rates.shtml Above link suggests that today's interests are: i) Chinese RMB... bid: -12, offer: -11 (pls note the -ve signs for both bid and offer) ii) USD... bid: 2.4, offer: 2.95 Why are there negative signs for both bid and offer for RMB???? Does it mean that no matter I buy or sell I need to pay >10% margin??? It is strange as most of time we should get interest if I buy a currency. Is it b'coz RMB is not easily available so they need to borrow from somewhere else? Anyone can give me some insights?
