—Debt: Mexico returned to the samurai market on 28 August, placing 282.8 billion yen (US$1.78 billion) in four tranches, its first yen sale in two years.
—Rating: The bonds are senior unsecured obligations rated in line with Mexico’s Baa3 grade from Moody’s, which cut the sovereign to that level in May.
—Credit: Bank lending to the private sector accelerated to 3.0 percent real annual growth in June, the fastest of 2026, with preliminary readings near 3.3 percent for July.

The Mexican peso August performance was its best since April, capping a month in which the sovereign returned to Japan’s bond market, bank lending accelerated and stocks held near record territory.
Mexican peso August rally: strongest month since April
Mexico’s currency spent August grinding stronger. From levels around 17.36 per dollar at the end of July, the peso closed the month near 17.04, a gain of about 1.9 percent on market closing data. Banco de México’s official FIX rate printed 17.0427 on 28 August, and interbank spot traded as strong as 16.94 earlier that week.
That makes August the peso’s best month since April, when it gained roughly 2.1 percent. The driver has not changed all year: a wide interest-rate differential. Banxico has held its reference rate at 6.50 percent since May, while the US Federal Reserve’s policy rate sits well below that, keeping the carry trade in peso assets attractive for global investors.
The currency’s resilience is striking against the domestic backdrop. Banxico cut its 2026 growth forecast to 1.1 percent in its first-quarter report, and private-sector analysts surveyed by the central bank expect the peso to end the year weaker, with a December median near 17.9 per dollar. August’s close is far stronger than that consensus.
Back to Tokyo: the samurai bond return
On 28 August, the finance ministry (SHCP) placed 282.8 billion yen (US$1.78 billion) in samurai bonds, Mexico’s first yen-denominated sale since August 2024, when it issued 152.2 billion yen (US$955 million). The transaction, first reported by IFR, was structured in four tranches.
The largest piece was 177.3 billion yen (about US$1.12 billion) over three and a half years at 115 basis points above the yen swap rate. A five-year tranche of 87.2 billion yen (about US$549 million) priced at 140 basis points over, with smaller 10-year and 20-year lines of 1.2 billion yen (about US$7.6 million) and 17.1 billion yen (about US$108 million) at 170 and 210 basis points over, respectively. Seven- and 15-year tranches were marketed but withdrawn before pricing.
Demand exceeded the underwriters’ own expectations — notable, because bankers had worried that Mexico’s credit rating would deter conservative Japanese buyers. The notes are senior unsecured obligations, rated in line with the sovereign’s Baa3 grade from Moody’s, which cut Mexico from Baa2 in May citing fiscal rigidity, a narrow tax base and continued support for Pemex. S&P had moved its outlook to negative days earlier.
Proceeds fund general budgetary needs and projects tied to the Sustainable Development Goals in the 2026 budget. Strategically, the sale keeps Mexico present in a market where regional banks, credit cooperatives and life insurers rarely buy dollar or euro debt. Official projections show 62.4 percent of Mexico’s foreign-currency debt is in US dollars and 19.6 percent in euros; the yen book remains small but diversifying. With the Bank of Japan’s policy rate now at 1 percent, pricing was tighter than in 2024, and debt managers hedged the currency mismatch with cross-currency swaps.

Bank lending finds momentum
The domestic financial system added a quieter positive. Outstanding bank credit to the non-financial private sector grew 3.0 percent in real annual terms in June, the fastest reading of 2026, according to BBVA Research, with preliminary figures pointing to about 3.3 percent in July. Deposits grew 3.1 percent in real terms, driven by time deposits.
In nominal terms, commercial bank financing to the private sector reached 7.79 trillion pesos (about US$458 billion) in June, up 7.1 percent from a year earlier, central bank data show. Consumer lending has done most of the work this year; corporate credit has lagged, weighed by uncertainty and soft industrial activity, and by a stronger peso that deflates the peso value of dollar-linked loans.
The trend matters because credit has been the missing leg of Mexico’s expansion. Three consecutive months of acceleration — from 1.5 percent real growth in May to above 3 percent by mid-year — suggest the cycle may be turning just as growth forecasts are being cut.
Stocks hold near highs
The S&P/BMV IPC index ended August at 65,484.32 points, slipping 0.53 percent on the final Friday and about 1.5 percent over the month, but still 11.5 percent above its level of a year earlier, according to central bank and market data. Measured over two years, the benchmark is up roughly 20 percent.
The equity story of 2026 has been one of resilience rather than exuberance: no major initial public offerings, but steady gains carried by industrials and consumer names, and renewed international attention after IPC futures began trading in Chicago. August’s modest pullback followed five months of accumulation.
Taken together — a firm currency with the Mexican peso August gain of about 1.9 percent, a successful return to Tokyo, accelerating credit and a stock index near highs — the month gave Mexico’s markets their most complete performance of the year, even as economists keep trimming growth forecasts.
