Ｍ1＝市民持有的法定紙幣和硬幣 + 持牌銀行客戶的往來(活期)存款
M1 =legal tenders in public circulation + demand deposits


Ｍ2＝M1 + 持牌銀行客戶的儲蓄存款及定期存款 + 由持牌銀行簽發並由非認可機構持有的可轉讓存款證
M2 = M1 + saving deposits and time deposits with licensed banks + NCDs issued by licensed banks held outside the monetary sector

Ｍ3＝M2 + 有限制牌照銀行及接受存款公司客戶的存款 + 由有限制牌照銀行及接受存款公司簽發，並由非認可機構持有的可轉讓存款證
M3 =M2 + time deposits with restricted license banks and deposit-taking companies + NCDs issued by restricted license banks and deposit-taking companies held outside the monetary sector

市民持有的法定紙幣和硬幣及持牌銀行客戶的往來(活期)存款沒有改變，因此ｍ１沒有改變
而持牌銀行客戶的儲蓄存款及定期存款卻改變了，因此ｍ２減小了２００百萬元

M1 no change (M1= C+ DD)
M2 decrease (M2= M1+ SD+ FD + CD all by licensed bank)
