The deflation myth

We’ve seen what printing does — the slow drain, and the catastrophic flood. So the fix seems obvious: a money nobody can print. But here economists raise their single loudest objection. Falling prices, they warn, are a disaster — a “deflationary spiral” that freezes the whole economy. It’s the argument used to justify why money must lose value forever. It’s also, on close inspection, mostly wrong.

The spiral story

The claim goes like this: if prices are falling, why buy today when it’ll be cheaper tomorrow? So everyone stops spending, demand collapses, businesses lay people off, prices fall further, and the economy spirals downward into ruin. To prevent this, central banks deliberately target around 2% inflation every year — a permanent, gentle erosion designed to keep you spending rather than saving. Told this way, it sounds airtight. But it hides a sleight of hand.

Two completely different things wearing one name

The word “deflation” is used to smuggle two opposite phenomena together:

• Monetary collapse (the bad kind) — the money supply itself implodes as banks fail and credit vanishes, as in the Great Depression. That is genuinely destructive — but the disease is a banking collapse, not the falling prices, which are merely a symptom.
• Growth deflation (the good kind) — prices fall because we get better at making things. Technology and competition make goods cheaper year after year. This is the normal, healthy signature of a productive economy, and it makes everyone richer in real terms.

The spiral argument takes the horror of the first and quietly applies it to the second. They are not the same thing at all.

You already live happily with deflation

Computers, televisions and phones get dramatically better and cheaper every single year. By the spiral logic, no one should ever buy one — you’d always wait for next year’s cheaper, better model. Yet these are among the best-selling products on earth. People buy the moment the value to them exceeds the price. Entire industries have boomed for decades under relentlessly falling prices. The claim that “no one would buy anything if prices fell” collapses the instant you look at the device you’re reading this on.

History already ran the experiment

For much of the 19th century, under a hard-money gold standard, prices gently fell for decades — and it was one of the greatest periods of growth, industrialisation and rising living standards in human history. Wages bought more each year. Deflation and prosperity coexisted comfortably, exactly as the “good kind” predicts. The idea that stable or falling prices must mean stagnation simply isn’t what the record shows.

What this means for Bitcoin

A money that gently gains purchasing power over time is not a trap — it’s arguably how money is supposed to behave. It lets ordinary people save without gambling in markets just to stay level: your work, stored as money, would buy more in the future, not less. You wouldn’t need to become an investor simply to avoid getting poorer. Bitcoin’s fixed supply makes it the first truly deflationary money we can all hold — and understanding why that’s a feature, not a flaw, is one of the biggest unlocks in this whole course.

Sound money removes one great danger: debasement. But there’s a different fragility built into how banks hold our money, whatever it happens to be worth — because they don’t actually keep it all. What happens when everyone asks for theirs at once? Bank runs, next.

Key takeaways

• The scary ‘deflationary spiral’ conflates two different things: a monetary collapse (banks/credit imploding, e.g. the Great Depression) which is genuinely bad, and growth deflation (prices falling because we get more productive) which is healthy and makes everyone richer.
• We happily buy electronics that get cheaper and better every year, and the 19th-century gold standard saw decades of falling prices alongside strong growth — so a money that gently gains value, like Bitcoin, is a feature, not a flaw.
