An important consideration for investors is where the bonds are issued and traded; this affects applicable laws, regulations, and tax status.
The bond market can be classified into two markets: an internal market and an external market.
Internal Bond Market
The internal bond market is also called the national bond market. It is divided into two parts: the domestic bond market and the foreign bond market. The domestic bond market is where domestic issuers issue bonds and where these bonds are subsequently traded.
A foreign bond (called a Yankee bond in the U.S., a Samurai bond in Japan, and a Bulldog bond in the U.K.) is a bond issued in a country's national bond market by an issuer not domiciled in the country where those bonds are subsequently traded.
External Bond Market
This market is also referred to as the international bond market, the offshore bond market, or the Eurobond market. The bonds in this market are:
Eurobonds are subject to a lower level of listing, disclosure, and regulatory requirements than domestic or foreign bonds.
Eurobonds are classified according to the currency in which the issue is denominated. For example, if a Eurobond is denominated in U.S. dollars, it is called a Eurodollar bond. A USD bond issued by Ford and sold in Japan is thus called a Eurodollar bond, not a Euroyen bond.
A global bond is a debt obligation that is issued and traded in both the Eurobond market and at least one domestic market (for example, a USD bond issued by the Canadian government sold in the U.S. and Japan). Issuers of global bonds typically have high credit quality, and regularly have large fund needs. The first global bond was issued by the World Bank.
In general the income portion of a bond is taxed at the ordinary tax rate. Some countries implement a capital gains tax. Some countries even differentiate between long-term and short-term capital gains. There may be specific tax provisions for bonds issued at a discount or bought at a premium.
