See this note to explain the jump in late 2022 -- January 18, 2023 --  it was Putin simply moving money from one pocket to another pocket, in this case, converting the country's pension fund (held/paid in rubles) into foreign exchange reserves (generally western currency).

For those still confused: Putin doesn't pay his pensioners their social security in dollars.

The chart was re-set in October 2022 when Putin began having trouble financing his war.
