Bonds are IOUs from governments or corporations. When you buy a bond, you're lending money and getting paid interest for the favor. A $1,000 Treasury bond with a 5% yield pays you $50 a year. The bond market is actually way bigger than the stock market — over $130 trillion globally — and it's where the real institutional money lives. While retail traders obsess over stock tickers, the bond market quietly dictates interest rates, mortgage costs, and the overall direction of the economy.

The yield curve is one of the most powerful economic indicators in existence. Plot interest rates of government bonds from shortest maturity (3 months) to longest (30 years) and connect the dots — that's the yield curve. Normally it slopes upward because locking your money up for 30 years should pay more than 3 months. But when short-term bonds pay MORE than long-term bonds, the curve 'inverts.' An inverted yield curve has predicted every U.S. recession in the last 50 years. When this signal flashes, smart money starts preparing.

Why does an inverted yield curve predict recessions? When investors pile into long-term bonds, they're saying 'the future economy looks weak, so I want to lock in returns now.' When short-term rates are high, it's usually because the Fed is raising rates to fight inflation, which slows the economy. So an inverted curve means: the Fed is squeezing now AND investors think the future looks rough. That combination has historically led to recessions within 6 to 24 months.

Here's how this connects to your money. When yields rise, bond prices fall — they move inversely. For stock investors, rising bond yields create competition — why risk money in stocks when you can get 5% risk-free from Treasuries? That's why stocks often struggle when bond yields climb. Understanding the bond market tells you where interest rates are heading, whether a recession is coming, and how much competition stocks face for capital. Ignore bonds at your own risk.
