How Interest Rates make you Rich or Broke.

Hey friend,

There’s one number that affects every major financial decision in your life. It determines whether you can afford that house, whether your boss keeps hiring, and whether your credit card bill is manageable or crushing.

Most people have no idea what this number is or how it works. But the wealthy? They watch it like hawks and use it to get richer while everyone else struggles.

Today I’m explaining interest rates in plain English - what they are, how they work, and most importantly, how you can stop being on the losing side of this game.

 What Are Interest Rates, Really?

Think of interest rates as the price tag on money itself. When you borrow money, you don’t just pay it back - you pay extra for the privilege of using someone else’s cash. That extra cost is the interest rate.

But here’s what most people miss: interest rates aren’t just about your personal loans. They’re set by powerful organisations called central banks, and their decisions ripple through absolutely everything in the economy.

In America, it’s the Federal Reserve. In Europe, it’s the European Central Bank. These institutions decide how expensive it should be for banks to borrow money, and that decision flows down to every loan, mortgage, and credit card in the country.

When the Fed says “money is cheap,” everyone can borrow easily. When they say “money is expensive,” borrowing becomes painful.

 The House Example That Changes Everything

Let me show you how this works with a simple example that’ll blow your mind.

You want to buy a $300,000 house. You get a 10-year mortgage, and let’s say the house appreciates to $400,000 over that decade.

Scenario 1: Low Interest Rates (3%)

Your monthly payments over 10 years cost you about $350,000 total. Since the house is worth $400,000, you’ve made $50,000. Nice!

Scenario 2: Medium Interest Rates (6%)

Now your total payments are much higher. After 10 years, you’ve paid almost exactly what the house is worth. You break even, but barely.

Scenario 3: High Interest Rates (8%+)

Your payments are so high that you end up paying more for the house than it’s actually worth. You’re losing money just because borrowing got expensive.

Same house. Same person. The only thing that changed was the interest rate.

This is why smart people pay attention to these numbers. The difference between 3% and 8% isn’t just math - it’s the difference between building wealth and going broke.

Why Not Keep Rates at Zero Forever?

If low interest rates make everything affordable, why don’t central banks just keep them near zero all the time?

Here’s the problem: when money is super cheap, everyone goes crazy with borrowing. People buy houses they can’t really afford. Companies expand too fast. Investors bid up prices on everything.

At first, it feels awesome. Everything seems like a bargain. But all that cheap money creates demand faster than we can create supply, so prices start climbing rapidly.

Before you know it, you’re not buying a deal anymore - you’re buying into a bubble. And bubbles always pop.

That’s when central banks step in and raise rates. Suddenly, borrowing becomes expensive, demand crashes, and prices fall. The party’s over.

The Boom and Bust Cycle

This creates a predictable pattern that repeats throughout history:

The Boom (5-10 years): Interest rates are low, money is cheap, prices climb steadily, everyone feels rich.

The Pop (1-2 years): Central banks raise rates, borrowing becomes expensive, demand crashes, prices fall fast.

The Recovery (5-10 years): Markets slowly climb back to previous levels and beyond.

The crazy part? The optimal time to buy is actually a tiny window at the beginning of each boom cycle. Miss that window, and you’re stuck either buying at the top or trying to finance purchases when credit is too expensive.

But here’s the key insight: over the long run, the trend is always upward. Markets recover, prices eventually rise, and patient investors win.

 Who’s Really Pulling the Strings?

Every major country has a central bank making these decisions. But because the US dollar is the world’s reserve currency, what the Federal Reserve does affects everyone on the planet.

When the Fed raises rates, money flows into America chasing higher returns. When they lower rates, money flows out to riskier investments around the world.

A small change in Washington can crash stock markets in Tokyo or destroy currencies in developing countries. We all saw this happen during the pandemic.

In 2020, the Fed slashed rates to nearly zero. Mortgage rates dropped to 3% - the lowest in history. Everyone could suddenly afford bigger houses, so they rushed in and prices skyrocketed.

By 2022, inflation was getting out of control, so the Fed flipped the switch. Rates shot past 7%. Overnight, the housing market froze. Same houses, but now nobody could afford them.

 How the Rich Use Cheap Money as a Weapon

When interest rates are low, regular people notice their mortgage got cheaper. But wealthy people and corporations see something entirely different - they see an opportunity to get richer.

The Buy, Borrow, Die Strategy

Wealthy individuals play a similar game. Instead of selling stocks and paying taxes, they borrow against their assets.

Picture this: You own $100 million in stocks or real estate. When rates are low, you can borrow $20 million against that portfolio at maybe 2% interest.

Since it’s a loan, not income, you pay zero taxes on that money. You use it to fund your lifestyle, buy more assets, or invest for even higher returns.

If you can borrow at 2% and invest at 8%, you’re compounding wealth almost for free. When you die, your heirs often inherit the assets with tax advantages that wipe out the debt.

This is how billionaires live lavishly while paying minimal taxes.
