(this question refers to the US only)
We have official data on M2 by the Fed, but, if I understand correctly, this M2 data includes even bank deposits of firms/corporations where I am after the households.
In particular, I'm looking of M2 data by groups like wealth percentiles. We can see again from the Fed very nice tables and graphs on Distribution of Household Wealth that allow you to have those kind of queries. In the "Assets" we can find: Real estate, consumer durable goods, corporate equities and mutual found shares, pensions, private businesses or "other assets".
What I seek is basically bank deposits and saving accounts, I'm not sure this is what "other assets" stands for here. Where can I find this kind of information? Thanks.
