CCB structured deposits are not available every week, and there is no fixed time. Structured deposits refer to financial products with certain risks in which investors deposit legally held RMB or foreign currency funds into banks and banks embed financial derivatives (including but not limited to forwards, swaps, options or futures). On the basis of ordinary deposits, investors' income is linked to financial or non-financial objects such as interest rate, exchange rate, stock price, commodity price, credit and index.
