Yes. If the (overall) nominal money flows decrease but (overall) real economy size stays the same – to the extent that it’s going to change prices for no “real” reason – people and central banks are likely to notice and may react.

Central banks are tasked with stabilizing price levels. (Why? Predictability helps people make decisions and plans, and get rewarded for them. Caveat: price changes that originate in changes to real economy convey valuable information about real scarcities and surpluses. This one, kinda, doesn’t.) Prices are closely related to the ways money circulates in the economy – so CBs keep a close eye on these stats. (Why? In short, it’s a big factor in the simple monetary formula, MV=PQ, that is: overall amount of money * money velocity = price level * quantity of real consumption.) The fact you froze or burned a lot may influence how that looks, in turn possibly influencing CB decisions to put the finger on this or that scale.

Of course, the CB doesn’t know what you did exactly, it’s playing an aggregate game. Right now it would appreciate that you counteracted inflation – made everything a bit cheaper by not spending or loaning your billions for others to spend.
