Mexico's Ministry of Finance and Public Credit (SHCP) returned to Japan's capital market on August 28, 2026, with a multi-tranche Samurai bond issuance. This move marks the country's first yen-denominated debt issuance in two years, following a $955.03 million (YN¥152.2 billion) issuance in August 2024. The objective is to diversify public credit sources and reduce reliance on traditional Western capital markets, despite yen-denominated debt representing a small percentage of overall sovereign liabilities. The transaction targeted Japanese institutional investors, including regional banks, credit cooperatives, life insurance companies, and specialized investment funds.
The issuance is structured in up to six tranches with maturities ranging from 3.5 to 20 years. Historical data from Mexico's 2024 Samurai bond issuance showed Japanese financial institutions acquired 63% of the total offering. Commercial and regional banks typically absorb short- and medium-term maturities, while life insurance firms purchase longer-dated 20-year paper. Initial price talks for the new notes ranged from 100 to 200 basis points over Tokyo Overnight Average Rate (TONAR) mid-swaps, depending on maturities.
This return to the Japanese market occurs amidst shifting macroeconomic conditions. The Bank of Japan recently raised its benchmark policy rate to 1%, concluding its era of negative interest rates. This forces Mexico to offer higher coupon yields to compete with attractive domestic Japanese debt instruments, especially with the Bank of Mexico maintaining its domestic reference rate at 6.50%. Additionally, foreign exchange exposure presents a risk, as yen appreciation against the Mexican peso directly increases debt servicing costs, although cross-currency swaps are used to mitigate this.
The Samurai bond issuance complements Mexico's broader 2026 external financing strategy, which includes a record $9 billion sovereign bond issuance in January 2026 and a $5.53 billion (€4.75 billion) sustainable bond placement in the European market. Mexico's 2026 Annual Financing Plan, approved by Congress, set an external debt ceiling of $15.5 billion. The Ministry of Finance projects the Historical Balance of Public Sector Financial Requirements to remain stable at 52.3% of GDP by the end of 2026.
This new sale comes as Mexico faces pressure on its credit ratings. In May, S&P Global Ratings revised its outlook to negative, citing poor fiscal results, rising debt, and weak economic growth. Moody’s Ratings also cut Mexico to the lowest tier of investment grade, highlighting concerns over continued support for Petroleos Mexicanos. Additionally, the U.S. announced in July that it would not renew the United States-Mexico-Canada Agreement, opting for annual reviews instead, creating further trade uncertainty.
