2020年5月的改变是把原本只算进M2不算进M1的Savings Deposits算进M1。因为M2包括M1，因此M2没变，

而是M1变多了。参考以下Federal Reserve的announcement:

First Monthly H.6 Statistical Release

As announced on December 17, 2020, the Board's Statistical Release H.6, "Money Stock Measures," will recognize savings deposits as a type of transaction account, starting with the publication today. This recognition reflects the Board's action on April 24, 2020, to remove the regulatory distinction between transaction accounts and savings deposits by deleting the six-per-month transfer limit on savings deposits in Regulation D. This change means that savings deposits have had a similar regulatory definition and the same liquidity characteristics as the transaction accounts reported as "Other checkable deposits" on the H.6 statistical release since the change to Regulation D. Consequently, today's H.6 statistical release combines release items "Savings deposits" and "Other checkable deposits" retroactively back to May 2020 and includes the resulting sum, reported as "Other liquid deposits," in the M1 monetary aggregate. This action increases the M1 monetary aggregate significantly while leaving the M2 monetary aggregate unchanged.
