Right, unless you're stashing currency into your mattress or burying gold bars in the yard, your money hasn't gone anywhere. It's in the bank, which is the lending it out to those who have a a better user for it. Hoarding is a an invented scary word for saving. Saving is the underpinning of all investment, and investment is the key to productivity gains. Productivity gains are the key to increased living standards.

To then turn that upside down and say that saving makes things worse is only possible by using the word 'hoarding' as it conjures images of a fleeing deposed lord burying the family treasure in a field.

In reality, returning economies to health requires a stable or increasing rate of savings.

The problem is that a Fetishistic obsession with 100% cash savings instead of actually investing in something is not a good thing for the economy.

It also leads to bizarre outcomes where foolish pensioners invest in exotic and risky cash like instrument's like PIBS instead of 100+ year old investment trusts.

Yes, but you're saving to accumulate an amount with some particular purpose, usually not because your money will theoretically buy you more tomorrow (likely it will buy you less in the normal inflationary version of the world).

Hoarding is something like but not quite exactly the same as saving.
