Bonds are interest-bearing securities that represent the issuer's obligation to repay interest (the so-called coupon) and borrowed capital within the agreed terms. The owner of the bond is a creditor of the issuer. An investor can get a double return - a coupon and possibly a profit from the exchange rate difference in the event of a favorable change in the bond price. Within the general group of bonds, there are other subgroups that have their own specifics, which you can read about below.
