Yield Curve

Investments

The yield curve plots interest rates of bonds of equal credit quality but different maturities. A normal (upward sloping) yield curve means longer maturities pay higher rates. An inverted yield curve (short-term yields higher than long-term) has historically predicted recessions 12-18 months ahead.

In detail

Yield curve shapes:nNormal (upward slope): healthy economy. Investors expect growth. 10-year bond yields more than 2-year.nFlat: economic uncertainty. Short and long yields similar.nInverted: recession signal. Short-term yields exceed long-term. Happened in USA before 2008, 2020 recessions.nnIndia G-Sec yield curve (2024):n1-year: approximately 6.9%n3-year: approximately 6.95%n5-year: approximately 7.0%n10-year: approximately 7.05%nNormal, mildly upward slope.nnFor debt fund investors: in falling rate environment (when RBI cuts rates), long-duration funds benefit most (prices rise as yields fall). Short-duration funds are safer when rates are uncertain.

Formula

Yield curve spread = Long-term yield - Short-term yieldnPositive spread (normal): long > shortnNegative spread (inverted): short > long

Real-life example

🇮🇳 India example

RBI signals rate cuts in 2024. Yield curve steepens: 10-year bond yield at 7.2%, 1-year at 6.8%. Spread = 0.4%. Debt fund manager extending duration (buying 10-year bonds): benefits from price appreciation as rates fall. If 10-year yield falls from 7.2% to 6.8%: bond price rises approximately 3-4% (modified duration effect). This is how long-duration debt funds generate returns beyond just interest.

Frequently asked questions

Should I invest in long-duration debt funds when RBI signals rate cuts? ▼

Potentially yes, but it is not as simple as it sounds. Bond prices and yields move inversely. When rates fall, long-duration bond prices rise significantly. But timing is difficult. Consider: gilt funds or long-duration debt funds only for 20-25% of debt allocation, only when RBI is in a clear rate-cutting cycle, and only if you can hold for 2-3 years.
