Hi i had a simple question. When the yield curve steepens in the next few years, long bond prices will drop. The past 5 years long bonds fluctuate between 100 to 80. At what point would bonds be trading below 80 (30 year T bonds)? Theoretically at what interest rate? Is there a website that graphs the 30 year T bond prices for the past 20 years? (fluctuating from 80 to 100 dollars) Was looking all over the net for one , couldnt find a single chart.
