A little nitpicking.
What is this 0% rate? Is it the bond coupon rate (interest rate) that is determined at the time of issuing or the actual yield rate reflected in the market? Bond with 0% bond coupon rate can still be sold with discount, which means the market value of the bond is less than its face value. There are many such bonds in the market. It is the yield rate that investors care about, not much with the coupon rate. So, nobody may buy bonds with 0% yield but some will with 0% bond coupon rate (interest rate).
