Purchasing Power of the Pound (Last ~80 Years)
Down.
 

The Silent Decline of the Pound

Most people believe their money is stable.

After all, £10 is still £10… right?

But what really matters isn’t the number on the note, it’s what that note can actually buy.

And over the last 80 years, that has changed dramatically.

What the Data Shows

Since the end of World War II, the British pound has lost over 95% of its purchasing power.

What £100 could buy decades ago… today requires thousands.

This hasn’t happened overnight. It’s been a slow, persistent erosion. So slow, in fact, that most people never question it. it is silent. Can you hear it?

Why This Happens (The Core Issue)

Modern currencies are no longer backed by anything physical. Nothing. 

They are backed by confidence.

And crucially, they can be created at will, when ever they want. 

When governments face:

  • Economic crises
  • War
  • Rising debt

They don’t raise taxes immediately.

They print money.

The Problem With Printing Money

Printing money doesn’t create wealth.

It simply increases the supply of currency.

And when supply rises faster than real economic output:

Each unit of currency becomes worth less

This is currency debasement.

Why This Is Set to Continue (and Accelerate)

The pressures today are greater than ever:

  • Record global debt levels
  • Ageing populations (higher government spending)
  • Ongoing geopolitical conflict
  • Energy and supply chain instability

The easiest political solution?

More money creation.

The Key Takeaway

This isn’t a one-off event.

It’s a structural feature of the system.

And it means: Holding cash long-term is not “safe” , it’s a guaranteed loss in real terms.
