International Bond Map: Yankee · Eurobond · Samurai · Formosa · Arirang
Modern bond issuers are not confined to a single domestic market. A Korean company can raise dollars in New York, borrow yen in Tokyo and swap to dollars via CCS, and sell euro bonds to Taiwanese insurers. Each market has unique currencies, regulations, and investor bases, requiring strategic choices. This chapter dissects the key differences and selection criteria for the five major international bond markets.
Why Is the Domestic Market Not Enough?
When companies in smaller economies need to raise large sums, the domestic bond market alone has limitations. Korea's annual corporate bond issuance is around $15bn. Meanwhile, Korean conglomerates routinely raise $1bn in a single Eurobond deal. Four key reasons drive the need for international bond markets.
Investor Diversification
Relying only on domestic investors risks saturation of specific investor groups. International issuance simultaneously accesses European, US, and Asian investors, deepening the order book and improving pricing.
Currency Diversification
Globalized business operations require liabilities in dollars, euros, yen, and more. Issuing directly in the relevant currency market provides a natural hedge.
Rate Arbitrage
Interest rates differ across countries. Issuing in low-rate JPY and swapping to USD via CCS can achieve lower funding costs than issuing directly in USD markets.
Regulatory Arbitrage
The Eurobond market is not subject to any single country's regulations, enabling very fast execution. Yankee requires SEC registration but dramatically improves US institutional investor access. Issuers trade off regulatory burden against investor access.

Want to understand CCS structure and Basis Spread in depth?
DCM Special — SOFR, LIBOR, Mid-Swap & CCS Deep-Dive →Cross-Currency Swap (CCS): Why Borrow Yen to Fund in Dollars?
A Korean conglomerate CFO might receive this report: 'We issued a 10-year JPY Samurai bond in Tokyo today and locked in USD SOFR+20bp.' The CFO might wonder: why issue yen bonds if we need dollars? This question gets at the essence of Cross-Currency Swaps (CCS).
CCS 3-Step Mechanism
Issue JPY bond to Japanese investors. Coupon 0.3%, 10yr. Raise ¥10bn.
Execute CCS with swap bank: exchange ¥10bn for USD. Pay USD SOFR+20bp over 10yr, receive JPY 0.3%.
At maturity, return USD principal to swap bank, receive JPY to repay bondholders.
Real Cost Comparison Example (2025 market assumptions)
| Issuance Route | Nominal Rate | CCS Cost | USD All-in Cost |
|---|---|---|---|
| Eurobond USD direct | SOFR+80bp | N/A | SOFR+80bp |
| Samurai JPY → CCS USD | JPY 0.3% | +CCS basis -60bp saving | SOFR+20bp |
| Yankee USD (SEC registered) | SOFR+70bp | N/A | SOFR+70bp |
The key to achieving SOFR+20bp via the Samurai route is the 'Basis Swap Spread.' This spread reflects supply-demand imbalances for specific currency pairs and fluctuates with market conditions. A JPY/USD basis of -60bp saves 60bp when swapping from JPY to USD, but if the basis reverses, the advantage disappears. Issuance timing is therefore determined by close monitoring of CCS basis spread levels.
Which Market Should You Choose? Issuance Market Selection Guide
When an issuer launches a global bond, bankers simultaneously compare 'what rate can we achieve in which market' across multiple venues and present the optimal recommendation. Here are the four core criteria considered in order.
① What currency do you actually need?
If you need USD/EUR, Eurobond or Yankee is the baseline. If you hold JPY assets (Japan business), direct Samurai issuance provides a natural hedge. If you need KRW, consider Arirang, but practical demand is limited.
② Does execution speed matter?
If the market window is narrow or a swift funding match to an M&A closing is needed, Eurobond is optimal. No regulatory registration; bookbuilding can happen within 1–3 days. Yankee is fast if SEC registration is already in place, but initial registration takes months.
③ Is US investor access strategically important?
US life insurers, pensions, and mutual funds provide the world's deepest bond liquidity. For long-dated (20–30yr) or large transactions ($3bn+), Yankee or 144A/Reg S structure is essential. US investors cannot purchase Reg-S-only Eurobonds.
④ Is the CCS basis spread favorable?
Finally, check the JPY/USD or EUR/USD CCS basis spread. If the basis is sufficiently negative (i.e., significant savings by issuing in a low-rate currency then swapping), indirect USD/EUR funding via Samurai or Formosa can beat direct issuance. This decision is updated daily with market data.
Market Selection Matrix
| Market | Ideal Issuer | Key Advantage | Key Constraint |
|---|---|---|---|
| Eurobond | IG issuers, speed priority | Widest pool, fast execution | US investors need 144A |
| Yankee | Large IG, long-dated needs | Direct US access, long-dated demand | SEC registration cost/time |
| Samurai | When CCS basis favorable, use low JPY rates | Low JPY rates + CCS savings | Complex process, CCS basis volatility |
| Formosa | Issuers targeting Taiwan insurers | Direct access to Taiwan insurer FX demand | Narrow investor pool, Taiwan rules |
| Arirang | Strategic Korean investor access (multilaterals) | KRW liquidity, Korean diversification | Small market, higher KRW rates |
Rule 144A / Reg S: Covering Both Markets Simultaneously
Many large issuers simultaneously execute Eurobond (Reg S) and Yankee (144A) in a single transaction. This is called a '144A/Reg S' structure. Technically two separate ISINs are issued, but bookbuilding happens simultaneously under identical terms.
For non-US investors. No SEC registration. Listed in Luxembourg/Ireland. Global AM, insurers, pensions.
For US QIBs (Qualified Institutional Buyers). Uses SEC registration exemption. Same terms, same deal.
Simultaneous global investor access → maximize order book → minimize funding cost. Concentrated liquidity from market integration.
