Is there a quick back of the envelope way to guess how much interest rates will fall or rise when the futures of say the 10-year, rise or fall a certain amount? Looking for something I can do in my head on the run, not a formula ...
When the bond futures had an 8% coupon, it was usually 4 ticks per basis point of yield; i.e. a 20 tick move produced ~5 basis points of yield change. With the 6% coupon, it's around 3 ticks per basis point of yield change. It's an "approximate" guideline.
