The US 30-year Treasury yield reached 5.28 per cent on July 31, 2026, the highest level since July 2007, according to Market-TOI. The 20-year yield rose to a high of 5.3 per cent in July, its highest since 2023, and the 2-year, 5-year and 10-year tenors all breached their respective 2025 highs, the report said. Treasury yields have been climbing since the US-Iran war began, reversing the decline seen in the early months of the year.
For CFOs and treasury directors, the rise in long-term yields directly lifts the cost of dollar-denominated debt used in trade and project finance. The 10-year yield, the article's reference tenor, closed at around 4.16 per cent in December 2025, rose to a high of 4.3 per cent in early February, then dropped to a low of 3.93 per cent on March 2, 2026, before reversing course.
Rate-Cut Prospects Fade
The Federal Reserve had projected a 50 basis points interest-rate cut in 2026, after reducing rates by 25 bps in December 2025 to 3.5-3.75 per cent, according to Market-TOI. The central bank's economic projections left the door open for another 50-bps cut, and this expectation was a major factor weighing on yields at the start of the year.
Oil and Inflation: The Reversal Trigger
The reversal began with the US-Iran conflict. Oil prices surged as the war started, driven by the fear of supply disruption following the closure of the Strait of Hormuz. West Texas Intermediate crude futures traded on NYMEX spiked from around $67 per barrel to a high of approximately $115 per barrel in just one week, the article reported. The contract then traded in a wide range of $85-107 until mid-May, fell to a low of about $67 again in early July, and is now around $75.
Elevated inflation concerns emerged as oil spiked, pushing US headline CPI from 2.4 per cent year-on-year in February to 4.2 per cent in May, Market-TOI said. That inflation pressure has aided the move higher in yields.
Yield and Commodity Outlook
As long as the war continues, oil prices will remain the major driver of US yields, according to the article's technical analysis. WTI crude, currently at $75, has a cluster of supports in the $65-60 region, and unless the war ends, a move below $60 is unlikely, according to Market-TOI. The publication sees potential for a return to $100 and $110, and up to $130 if the situation escalates, with a broad expected range of $60-120.
| US Treasury Yield Moves | Level | Date | Milestone |
|---|---|---|---|
| 30-year | 5.28% | July 31, 2026 | Highest since 2007 |
| 20-year | 5.3% | July 2026 | Highest since 2023 |
| 10-year | 4.16% close | December 2025 | Year-end level |
| 10-year | 4.3% | Early February 2026 | High |
| 10-year | 3.93% | March 2, 2026 | Low |
High oil prices can keep the US yields higher. Oil prices must decline below $60 for the US yields to go down.
The FTSE CoreCommodity CRB Index, a basket of 19 physical commodities, is currently at 377. WTI crude oil has the highest weightage in the index at 23 per cent, according to Market-TOI, and the index's recent movement is in tandem with WTI. It has strong support around 335.
Implications for Trade Finance
For trade finance professionals, the sustained elevation of Treasury yields means higher dollar funding costs for importers and exporters. At the same time, headline CPI at 4.2 per cent in May raises the cost of goods and freight, particularly for oil-importing markets, while the Fed's projected 2026 rate cut of 50 bps now faces the constraint of war-driven inflation. The article's conclusion is straightforward: until oil prices fall below $60 per barrel, US yields are likely to stay elevated, keeping the cost of capital high for trade-dependent businesses.
