Yield volatility for a bond is estimated from historical data. Which statement about the term structure of yield volatility is most accurate?
The most accurate statement is that short-term rates are typically more volatile than long-term rates and volatility differs by maturity. This pattern, called the term structure of yield volatility, reflects short rates' sensitivity to monetary policy, whereas long rates move less.
- AShort-term rates are typically more volatile than long-term rates, and volatility differs by maturityCorrect
- BYield volatility is identical across all maturities on a given curve
- CLong-term yields have no volatility because they are anchored by inflation expectations
Explanation
The term structure of yield volatility shows that yield volatility varies by maturity, with short-term rates typically more volatile than long-term rates because they respond to monetary policy. Identical volatility across maturities contradicts this, and long-term yields do vary.
