Inflation and Deflation
What They Actually Are — and What They Signal to Consumers
Most people talk about inflation and deflation as if one is bad and the other is good.
That anchoring thought is lazy and completely wrong. Let me help you understand what inflation and deflation really are.
Inflation and deflation are not economic outcomes. They are guideposts that policy makers target and avoid. They are signals not destinations.
They tell consumers when to spend, when to save, and how to think about tomorrow relative to today.
That’s it nothing more. They signal behavior and indeed they create behavior.
It is not politics it is just incentives.
Inflation Is a Signal to Spend Now
Inflation is monetary devaluation. Sorry to bust your bubble on that. And I would argue as Milton Friedman would that it is completely unnecessary in a balanced economy where money and productivity rise equally.
Inflation occurs when the supply of money grows faster than the supply of real goods and services. When that happens, each unit of currency buys less over time if policy makers by their actions create money. We have figured out at least twice in our history that is easy to do when the currency becomes unanchored.
The signal to consumers is simple:
If something will cost more tomorrow, then somehow buy it today.
If a loaf of bread will cost more tomorrow, you buy it today.
If a car will cost more next year, you buy it now.
If housing prices are rising, you don’t wait you move capital into the asset before the dollar’s purchasing power erodes further.
This isn’t psychology. It’s incentive signaling and math.
Inflation penalizes holding cash. Money sitting idle loses purchasing power. As a result, inflation encourages consumers to:
spend rather than save,
invest rather than hoard,
borrow rather than wait.
Does it matter whether we need more cars, clothes, or houses?
From a macroeconomic standpoint, not really. That is not the point. If we stop buying new things that are more shiny even when the old thing can still work that could cause perceived problems. But only because we have been trained by policy.
Inflation doesn’t care about need.
It responds to incentives. The system creates incentive. We respond.
When policymakers expand the money supply beyond productivity growth primarily by excess government spending on social programs and defense, they manufacture urgency moving money into a system that is not ready with goods and services. Spending accelerates. Credit expands. Economic activity continues to move forward.
This is why modern economies tolerate and even target moderate rate of inflation. You did not see substantial inflation in the US economy until after 1913 and there is ample proof of long term price stability prior to the formation of the federal reserve and US income tax policy. While there were periods of significant inflation in the US economy before that time, deflation was also tolerated and acceptable. Today it is not.
Now it is also possible that from time to time in the aggregate, the consumer has fewer needs as money supply grows. With fewer needs for aggregate goods and services, excess money then finds its way into paper assets. But that is Ray Dalio’s lane.
Deflation Is a Signal to Wait
Deflation is the mirror image.
When prices fall, the purchasing power of money increases over time provided wages do not fall as fast. The signal changed from the AC of inflation to the DC of deflation:
Why buy today if it will be cheaper tomorrow?
Under deflation, consumers are rational to delay discretionary purchases.
Why buy a car now if it will cost less next year?
Why buy a house today if prices are trending lower?
Why spend savings if money itself is becoming more valuable?
Deflation rewards patience.
As a result:
saving increases,
spending slows,
credit contracts.
This is not because consumers are afraid.
It’s because waiting is rewarded.
Deflation tells people to preserve capital, not deploy it. All else equal, because our society is built on spending and consuming, and because inflation has pulled forward demand and borrowing overtime, deflation, and its slowing effect leads to job losses, wage contract and real fear of a spiral that policy makers just cannot allow. That spiral of course is the economy cleaning itself up of bad businesses, bad actors and just plain old excess that is unsustainable, and on I can go.
But this is an all else being equal conversation.
Savings and Credit Follow the Signal
These signals show up clearly in behavior:
Inflation environments
Savings rates fall
Consumption rises
Credit expands
Debt becomes more attractive because inflation erodes its real cost
Deflation environments
Savings rates rise
Consumption slows
Credit contracts
Debt becomes more expensive in real terms
Again, no judgement here nor political party affiliation here. I am just the party of Math. 1 + 1 = 2. Just incentives responding to price movement.
What If Prices Never Moved?
Now ask the real question.
What if prices stayed flat for years or decades?
No inflation. No deflation.
In that world, consumers would buy what they need and no more or no less.
There would be no urgency to spend early and no reward for waiting. Capital allocation would be driven purely by preference, utility, and productivity.
That world would be stable. It would also be a ton slower in GDP growth and paper asset value expansion. The false sense of being a millionaire today when that million is only worth $100,000 yesteryear dollars is a false feeling of weath.
Modern economies are built on movement, not stasis. Inflation and deflation are tools and far more blunt ones than the average bear thinks. Those signals influence behavior to keep the system dynamic. Make no mistake about it, societies, governments and central banking regulators have every incentive in the world to create inflation and none to create deflation. So what does Wimpy say?
I would gladly pay you Tuesday with substantially less valuable dollars if you will sell me a hamburger today at today’s price.
Why Neither Is Good Nor Bad
Inflation isn’t evil. Deflation isn’t virtuous.
They are simply price signals about time.
Inflation says: Tomorrow is more expensive.
Deflation says: Tomorrow is cheaper.
Problems arise not from the existence of these signals, but from:
their speed,
their magnitude,
and whether wages and productivity adjust alongside them.
Understanding this framework helps us better understand the entire conversation about inflation since now we can know what it really is and why deflation is something some people fear.
Inflation and deflation don’t tell you what to think.
They tell you when to act.
Closing Thought
Money is not wealth. It is a claim on future goods.
Inflation weakens that claim over time and encourages action today.
Deflation strengthens it and encourages full stop restraint on unneeded purchase first then necessary goods and services can suffer.
That’s the whole story. Everything else is noise to try to get your vote.
Wait a minute!!!!
Epilogue - What I really Think!
Sandcastles, Signals, and the Lie We Tell Ourselves
So what the hell does inflation, deflation, and monetary signaling have to do with building sandcastles at the beach or buying a vacation home for your family?
Everything.
Because at its core, this was never an economics paper.
It was a paper about time.
Inflation is a signal that says tomorrow costs more.
Deflation is a signal that says tomorrow costs less.
But life doesn’t operate on price indices. It operates on windows of time and experience.
There is a window where your kids still want to build sandcastles with you.
There is a window where they still reach for your hand without irony.
There is a window where “someday” actually exists.
There is a window where you “kids” are now your grandkids and you move a little slower.
There is a window when you will reach for a hand and maybe find it just a memory.
There is a window where someday was yesterday.
People obsess over whether it’s a “good time” to buy a vacation home.
They ask about rates, cycles, appreciation, taxes, and timing.
Those are real questions. They matter a bit.
There are realtors that are trying to sell you the investment dream, the bonus depreciation trick idea and then there are those that have lived a bit, gathered some scars along the way and realize what they are trying to do is to help others live with life scars more intentionally and more graciously with more joy.
I wonder about this when I say it. Do people really care that much or will they just work with anyone that can spin a lockbox code?
The question is this:
What signal are you responding to, money, or life?
Inflation teaches people to act before value erodes.
Life should do the same thing only quietly, without a CPI report.
Time will be more expensive tomorrow. There will be less time tomorrow and more demand for it as we age.
And unlike currency, you cannot print more of it.
So if you’re asking what inflation and deflation have to do with vacation homes, sandcastles, and family
Oh yes…….actually……..Nothing at all.
You cannot build sandcastles on the beach with your grandbabies on a pile of bitcoin.
