US Treasury bond hits 19-year high and makes emerging debt more expensive

The 10-year US Treasury bond reaches 5.02%, its highest in 19 years, with Brent above 108 dollars and the peso at 17.15. Key for emerging debt.

The yield on the 10-year US Treasury bond reached 5.02% on Tuesday, September 15, 2026, a level not seen since the 2007 global financial crisis, according to Al Jazeera. The benchmark that governs the cost of credit in US markets is rising in parallel with crude oil, which topped 100 dollars a barrel.

The trigger is energy. La Jornada reported that Brent closed on Monday, September 14 at 108.92 dollars a barrel, a gain of 4.12%, and West Texas Intermediate at 103.92 dollars, after new attacks on Saudi energy infrastructure and on vessels near the Strait of Hormuz. For Mexico the transmission channel is mechanical: a more expensive Treasury bond makes dollar financing costlier for sovereign and corporate emerging-market issuers, and a stronger dollar pressures the exchange rate. That same Monday the peso closed at 17.1557 units per dollar, a depreciation of 1.12%, and the DXY index advanced 0.52%, to 99.352 points.

The repricing is not an exclusively American phenomenon. The 10-year German bond, the eurozone benchmark, touched 3.554% on Monday, its highest since mid-2009, and the Japanese 10-year bond surpassed 3% for the second time this month, its highest level in three decades, according to Al Jazeera. The European Central Bank raised its rates last week to contain inflation, and markets expect the Federal Reserve and the Bank of Japan to do the same at their meetings this week, the outlet adds. On the currency front, Forbes México carried Banorte's projection of a range of 16.50 to 17.50 units per dollar for the coming months, with a close of 17.30 in 2026.

The Federal Reserve's decision, expected on Wednesday, September 16, is the next hard data point on the agenda, and the Bank of Japan and the Bank of England announce theirs the same week. For Mexican issuers, the benchmark to watch is the cost of dollar financing, which is set with the 10-year bond now installed above 5%.
