We Crash When Cheap Money Lies
One Takeaway
When interest rates are kept lower than they should be, it sends false signals to entrepreneurs and leads to unsustainable booms followed by painful busts.
The Developer’s Dilemma
Back in 2005, a real estate developers in Las Vegas looked at the numbers and saw opportunity everywhere. Interest rates were low. Credit was easy to get. Housing prices had climbed every year for a decade. Dozens of developers borrowed millions to build new subdivisions on the edge of the town.
By 2007, the homes were built. But the buyers never showed up. Not because the homes were bad. Not because Vegas stopped growing. But because the borrowing and credit that made all of it possible was built on signals that weren’t real.
Interest rates weren’t low because Americans were saving more and banks had extra capital to lend. They were low because the Federal Reserve had pushed them there, in addition to ratings policy changes and a decrease in foreign investment.
When rates adjusted, the easy credit disappeared. Buyers couldn’t get loans. Developers couldn’t sell homes. Entire neighborhoods sat empty. The developer didn’t make a reckless bet. He made a reasonable bet based on information that turned out to be false.
Now multiply that story by thousands of developers, in dozens of cities, across several industries and you start to see how an economy can boom and bust all at once.
Why Busts Hit Everything at the Same Time
We’ve been taught to think of recessions as a basic part of the economy. “What goes up must come down.” But that’s worth questioning. In a normal market, some industries grow while others shrink. That’s expected. Consumers’ wants change, technologies evolve, and seasons shift. But a bust that hits the whole economy at once? That’s a sign something deeper went wrong.
What’s the one thing that ties every industry together? Money and credit. If those are distorted, the problem doesn’t stay in one place. It spreads everywhere.
What Interest Rates Are Supposed to Tell Us
Interest rates are more than the cost of a loan. They’re a signal about time.
When people are saving more, there’s generally more money available to lend. Interest rates tend to fall, telling entrepreneurs: “Go ahead and use credit for longer-term projects. Consumer demand will be there when you need it.”
When people are spending more, less money is available. Rates tend to rise, telling entrepreneurs: “Now might not be the time for big, long-term bets.”
In a healthy economy, interest rates coordinate what producers are building today with what consumers will want tomorrow.
What Happens When That Signal Is Faked?
When central banks push interest rates below where the market would set them, they send a message that isn’t true: “People are saving. Long-term projects are safe bets.”
Entrepreneurs see that signal and respond. They launch big, ambitious projects — new subdivisions, commercial towers, factory expansions — that feel justified by the low cost of borrowing. For a while, everything looks great. Businesses expand. Stock prices climb. Wages and hiring pick up.
But under the surface, the growth is hollow. The projects being built don’t match what consumers actually want or can afford. The savings to support all that investment were never really there. Economists have a word for this: malinvestment. Not too much investment, but investment in the wrong things, guided by the wrong signals.
When Reality Shows Up
Eventually, the gap between what was built and what people actually want becomes impossible to ignore. Projects stall when demand doesn’t materialize. Borrowers struggle to repay debts taken on during the boom. Resources locked into unsustainable ventures have to be freed and redirected to where they’re actually needed.
That’s the bust. It’s painful. But it’s also the economy correcting itself clearing out the mismatches so resources can find their way to better uses.
The Farmer and the False Forecast
Here’s another way to see it. Imagine a farmer hears a weather forecast predicting record-breaking rainfall this year. Excited, he plants a water-hungry crop across every acre he owns.
For a few weeks, the fields look promising. But the rain never comes. The crops fail. The investment made perfect sense based on the forecast. The problem was the forecast was wrong.
That’s what artificially low interest rates and easy credit do. They tell entrepreneurs the economic equivalent of “it’s going to rain.” Entrepreneurs “plant” accordingly. When the rain doesn’t come, when the savings and ability to pay aren’t actually there, the crops fail.
What This Means
The business cycle isn’t some natural rhythm of the market process. It’s what happens when the signals that coordinate millions of decisions get overridden.
When interest rates reflect real saving and spending, entrepreneurs can plan with less uncertainty. When they don’t, even smart, careful people end up building the wrong things at the wrong time.
The bust isn’t a disease that needs more intervention to be sured. It’s the painful process of getting the diagnosis right and starting to heal.
The Bottom Line
The cause of economy-wide boom and bust cycle is bad information. When interest rates are manipulated, they stop reflecting existing conditions. Entrepreneurs then respond to signals that aren’t real, and the economy pays for it later. The best way to avoid the cycle isn’t better management of the boom. It’s letting interest rates tell the truth in the first place.
