Why in the news

Surging G-Sec yields hurt returns of long-duration debt funds, mostly dynamic bond and G-Sec funds with long maturities.

Key facts

  • Long-duration funds: invest in long-term bonds; very sensitive to rate moves (duration).
  • G-Secs: sovereign-backed; T-bills run under 1 year, bonds 5 to 40 years.
  • Yield rise drivers: inflation fears, RBI’s cautious stance, bigger borrowing.

Exam angle
