What are samurai bonds and how do they fit into the global bond market taxonomy?

Samurai bonds are yen-denominated bonds issued in Japan by non-Japanese entities. They are registered with the Japanese Financial Services Agency and sold to Japanese investors.

Global Foreign Bond Taxonomy:

Memory Aid: The bond is always named after the domestic market — a samurai is Japanese, a yankee is American, etc. The ISSUER is always foreign.

Why Issue Samurai Bonds?

1. Low interest rates: Japan's historically low rates (often below 1%) make yen borrowing extremely cheap
2. Investor base access: Japanese institutional investors (banks, insurance companies, pension funds) hold enormous assets and actively seek yield
3. Diversified funding: Reduces dependence on home currency debt markets
4. Currency strategy: If the issuer expects yen depreciation, the effective borrowing cost in their home currency could be even lower

Example:

Pacific Infrastructure Corp (an Australian company) issues a 5-year samurai bond at 0.8% in JPY. Australian dollar bonds would cost 4.5%. If the AUD/JPY exchange rate remains stable, Pacific saves 3.7% annually. Even if the yen appreciates 2% per year, the net saving is still 1.7%.

Market Characteristics:

• Typical issuers: Sovereigns, supranational organizations, large corporations
• Typical maturity: 3-10 years
• Registration: Required with Japanese FSA
• Regulation: Subject to Japanese securities laws
• Typical size: JPY 30-100 billion ($200M-$700M)

Contrast with Euroyen Bonds:

Euroyen bonds are also yen-denominated but issued OUTSIDE Japan (typically in London). They face different regulations and access different investor pools.

CFA Exam Tip: The key is matching the name to the domestic market and currency. If a question describes a USD bond issued in the US by a German company, that's a yankee bond.
