เค้าคำนวณแบบนี้
Minimum FX Reserves = 10% of Exports + 30% of Short-term FX Debt + 10% of M2 + 15% of Other Liabilities
For China the equation is as follows: 10% * $2.2T + 30% * $680B + 10% * (RMB 139.3T / 6.6) + 15% * $1.0T = $2.7 trillion of required minimum reserves
Hayman Capital estimates that China's FX reserves right now are in a range of $2.1 trillion to $2.2 trillion if you take commitments to various bodies like China's sovereign wealth fund (CIC) into account.
