On a bond chart, I always see the terms: Yield & Coupon, which seem to mean the same thing. What is the difference between these two terms?

enter image description here

  • Notice that if the Bid is greater than 100, the yield is lower while if the Bid is lower than 100, the yield is higher.

Coupon tells us the rate of returns(%) for the bonds when it was first issued based on issue price

Yield tells us the rate of returns(%) for the bond based on current price

Assuming a bond was issued at $1000 , promising to pay $50 yearly , it has a coupon rate of 5% & yield of 5%. However, if due to unforseen circumstances the bond price drops to $500, it still has a coupon rate of 5% but the yield is currently 10%.

Coupon (%) = Returns / Issue Price * 100

Yield (%) = Returns / Current Price * 100

    Take a look at the YLD in OP's picture. It's not Returns / Current Price * 100. Else how does that zero coupon have any yield? That column is a YTM, Yield to maturity, which is a bit more complex, but takes the difference from today's price to face value into account. Mar 4, 2014 at 18:37
