Interest Rates and Bond Markets

Interest rates are the most important variable in all of finance. Every asset class - stocks, forex, commodities, real estate - is ultimately influenced by the level and direction of interest rates.

How Interest Rates Work

The Risk-Free Rate

• Government bond yields set the baseline for all investments
• US 10-year Treasury yield is the global benchmark
• All other assets are priced as a spread above this rate
• Higher risk-free rate = higher hurdle for all investments

The Yield Curve

• Plot of interest rates across different maturities
• Normal: Upward sloping (longer term = higher rate)
• Flat: Similar rates across maturities
• Inverted: Short-term rates higher than long-term (recession signal)
• An inverted yield curve has predicted every US recession since 1955

How Rates Are Set

• Short-term rates: Controlled by the central bank (Fed Funds Rate)
• Long-term rates: Set by the bond market (supply and demand)
• Central bank influences short end directly
• Inflation expectations drive the long end

Bond Market Fundamentals

Bond Prices and Yields

• Bond prices move INVERSELY to yields
• When rates rise, existing bond prices FALL
• When rates fall, existing bond prices RISE
• This is the most important relationship to understand

Why This Inverse Relationship?

• A bond pays a fixed coupon (e.g., 3% on $1,000 = $30/year)
• If new bonds pay 5%, your 3% bond is less attractive
• Your bond's price must drop so its yield equals the new market rate
• $30 annual coupon / $600 price = 5% yield (price dropped from $1,000 to $600)

Duration and Sensitivity

• Duration measures how sensitive a bond is to rate changes
• Longer duration = more price sensitivity
• A bond with 10-year duration drops ~10% for each 1% rate increase
• Short-duration bonds are safer in rising rate environments

The Yield Curve as a Predictor

Normal Yield Curve

• Economy is healthy and growing
• Banks can profit from lending (borrow short, lend long)
• Credit flows freely through the economy
• Positive for stocks and risk assets

Flat Yield Curve

• Transition period - economy may be changing direction
• Banks' lending margins compressed
• Credit conditions tightening
• Watch for further flattening or inversion

Inverted Yield Curve

• The market expects rates to be LOWER in the future
• This means the market expects economic weakness or recession
• Historically the most reliable recession predictor
• The lag between inversion and recession: 6-24 months

How Interest Rates Affect Markets

Stocks

• Rising rates: Negative for growth stocks (future earnings worth less)
• Rising rates: Can be positive for banks (wider lending margins)
• Falling rates: Positive for growth/tech stocks
• Rate of change matters more than absolute level

Forex

• Higher rates attract foreign capital
• Rate differentials drive currency pairs
• A country raising rates faster = stronger currency
• Carry trade: Borrow low-rate currency, invest in high-rate currency

Gold

• Inverse relationship with REAL interest rates
• Real rate = Nominal rate minus Inflation
• Negative real rates = very bullish for gold
• Gold competes with bonds as a "safe" asset

Real Estate

• Mortgage rates directly tied to bond yields
• Higher rates = less affordable housing
• Lower rates = housing boom
• REITs behave like long-duration bonds

Trading Bond Markets

Key Instruments

• Treasury futures (ZB, ZN, ZF, ZT)
• Bond ETFs: TLT (long), IEF (intermediate), SHY (short)
• Inverse bond ETFs: TBT (for betting on rising rates)

Key Data to Watch

• FOMC rate decisions and dot plot
• CPI and PCE inflation data
• Employment data (NFP)
• Treasury auction results
• Yield curve shape changes

Key Takeaways

1. Bond prices move inversely to interest rates
2. The yield curve predicts recessions when it inverts
3. Interest rate differentials drive currency markets
4. Real interest rates (not nominal) matter most for gold
5. Every asset class is ultimately influenced by interest rate levels
