I've been thinking about deposits and bonds. I live in Russia, and here some trustworthy banks offer deposits at the rate of 14.5% a year, and the interest is paid every month. The interests of Russian bond coupons vary, but on usual bond interest equals around 15-15.5% a year. As we all know, bond coupons are paid twice a year.
My question is the following: is it actually worth buying bonds in Russia instead of opening a bank deposit? After all, monthly interest results in higher compound interest in long-term investing than quarterly interest payments, doesn't it?
