US ten-year Treasury yield climbs to a 19-year high

The US 10-year Treasury yield rose 7.9 basis points to 5.244% on 28 September, its highest level since July 2007. The 30-year yield climbed to 5.55%, while the S&P 500 fell 0.77%.

Location: NEW YORK

According to Trading Economics data for 28 September, the US 10-year yield closed the day at 5.244%. That is 0.079 points higher than the previous session, 0.49 points higher than a month ago and 1.10 points higher than a year ago. The source described a level above 5.2 as the highest since mid-2007. It attributed the rise to oil prices, fuelled by the deadlock in talks over the Strait of Hormuz, and to firmer expectations of Fed tightening. On the same source's figures, markets see roughly a 65% chance of a rate hike at the October meeting and a 53% chance of a second move in December. The 30-year yield also rose 0.06 points to 5.55%, a monthly increase of 0.31 points at that maturity.

Vistap Global's market summary for 28 September showed the S&P 500 down 0.77% at 7,683.69, with the Nasdaq off 0.92% and the Dow 0.67% lower. The VIX volatility index jumped 8.33% to 16.11. According to Yahoo Finance's Zacks summary, the VIX had closed Friday 25 September at 14.87, when the 10-year yield stood at 5.23%. Vistap reported that the production index in the Dallas Fed's Texas manufacturing survey jumped from 16.1 in August to 29.5, with raw material and wage costs also rising. Trading Economics said investors are looking for direction from this week's PCE inflation figures, the Fed's preferred price gauge, and from the jobs data.

Talay assessment

Bottom line

The yield reaching its highest level since 2007 shows that the oil shock is now being priced through rate expectations. As the probability of an October hike rises, so does the cost of borrowing at extended maturities. This week's PCE and jobs data will either confirm or unwind that pricing. Until the data arrive, yields staying elevated is the most likely path.

Likely effects

  • US borrowing costsNegativeWeeks

    The joint rise in 10- and 30-year yields lifts mortgage and corporate borrowing costs and weighs on rate-sensitive equities.

  • TürkiyeNegative1–6 months

    A higher floor for US yields raises external borrowing costs and currency pressure for emerging economies; Türkiye is directly exposed through this channel.

  • Market volatilityUncertainWeeks

    Although the VIX has risen, it remains historically low; equities are so far meeting the yield rise with a gradual decline rather than panic.
