Money & Economic Foundations

They don't run the economy. They set the conditions.

The ECB, the Federal Reserve, the Bank of England. None of them decides a single price — and all of them shape the ground every price sits on.

The problem

A bank takes deposits you can withdraw today and lends them out for years.

That mismatch is normal. Watch what happens when everyone turns up at once.

🏦 Everyone wants their deposit back

CALM
Depositors withdraw faster than loans can be called in
Other banks stop lending to each other — nobody trusts the balance sheets
Credit dries up for companies and households
Investment is cancelled and jobs are at risk

Nothing unusual yet. Short-term deposits, long-term loans — that's just how a bank works.

Hands on

Both ends of the dial hurt.

This is the balancing act. There is no setting that's simply "safe".

BALANCED
Cost of credit for firms and households neutral
Risk of inflation, bubbles and excess debt contained
Risk of choking the economy contained

Roughly balanced: credit is available without obviously fuelling excess.

05

The limits

Not omnipotent.

A central bank can steer conditions and expectations. These it cannot do.
