# Monetary aggregates M1+, M1++, M2++

`GET /api/v1/boc/money-supply`

Canadian monetary aggregates in seasonally adjusted CAD millions:

- `V37151` - M1+ (currency plus personal chequable deposits)
- `V37152` - M1++ (M1+ plus non-personal chequable deposits)
- `V41552801` - M2++ (broadest measure, incl. mutual fund balances)

Year-over-year growth rates are published alongside the levels via `STATIC_ATABLE_V37151`, `STATIC_ATABLE_V37152`, and `STATIC_ATABLE_V41552801` from group `ATABLE_MONETARY_AGGREGATES`. Weekly cadence for M1+ and M1++, monthly for M2++.
