You are given the scenario below what is the best situation?

Three years ago Treasury spreads on 10-year BBB rated corporate bonds were 750 basis points. Treasury spreads on 10-year BBB-rated corporate bonds are 25 basis points

Bonds are exactly the same and carry the same risk, only the spreads and dates are different.

A) This suggests that BBB corporate bonds are deemed much more risky to investors today when compared to 3-years ago.

B) This means that we have likely moved from a recessionary environment (3-years ago) into a much more stable and strong economic environment

C) This means that 10-year Treasury bonds prices have increased more significantly than BBB rated bond prices

D) This suggests that trading liquidity in 10-year BBB bonds may have worsened over the last 3-years.
