On Thursday, September 24th, global interest rates, energy, and risk assets were simultaneously repriced under the same set of constraints. The yield on the 30-year US Treasury note rose to 5.44% intraday, the highest since 2004; the average global government bond yield rose to 3.99%, approaching 4%, returning to levels seen around 2007. Brent crude oil briefly broke through $106 per barrel amid concerns about the spillover effects of the Middle East conflict. Interest rate swaps have fully priced in three 25-basis-point rate hikes by the Federal Reserve over the next year, with a hedge reserved for a fourth rate hike. The three main themes—long-term compensation, policy path, and energy premium—have not diverged; they have simply spread the pressure across different accounts simultaneously.

Long-term government bonds are recalculating term premiums.

The sell-off in government bonds has spread from the long end of the US Treasury market to the global yield curve. The global government bond composite index yield rose 8 basis points to 3.99% on Wednesday; the yield on the five-year US Treasury note climbed above 5%, the first time since 2007; the ten-year yield hovered between 5.12% and 5.14%; and the 30-year yield rose to 5.44%. After the Asian market opened, the yield on the three-year Australian government bond jumped 13 basis points to 5.07%, the highest since May 2011; the two-year New Zealand bond yield briefly approached 4%; and the ten-year Japanese bond yield rebounded after the long holiday. The yield on the $70 billion five-year US Treasury note auction rose to its highest level since 2006, with weak demand indicators suggesting a declining capacity for the primary market to absorb supply. A portfolio manager at Columbia Securities said, "People are almost running out of new adjectives to describe the 30-year Treasury yield." "Investors' attitude is clear: if they want to lock in their money for 30 years, they need higher compensation." This statement doesn't refer to sentiment, but rather to the term premium. Locking up funds for 30 years is necessary to cover inflation stickiness, the pace of fiscal issuance, and refinancing risks. The global government bond index has already retreated by approximately 2.4% in 2026, while still recording a positive return of 6.8% in 2025. For highly indebted governments, rising interest costs will directly squeeze budgetary flexibility and force subsequent issuances to provide higher compensation.

The policy path has been locked in by the interest rate market.

The Federal Reserve raised its target range for the federal funds rate by 25 basis points to 3.75% to 4.00% in September. The median dot plot points to one more rate hike this year, and the core personal consumption expenditures price index forecast has been revised upward to 3.4%. Interest rate swaps have since moved even further: three 25-basis-point rate hikes over the next year have been fully priced in, and the market still has significant hedging for a fourth rate hike. The two-year Treasury yield rose above 4.7%, with short-term pricing realigning with the policy path. The dollar index is trading around 101, nearing its longest winning streak since May. The preliminary reading of the US composite purchasing managers' index for September was 58.4, the highest reading since July 2021, indicating that nominal activity is still expanding, but does not automatically equate to a fading of price pressures. A more useful observation for traders is that once energy and fiscal policy simultaneously raise the inflation center, central bank options will be limited, the weight of policy communication will decrease, and the swap curve will rewrite the discount rate before the statement.

How energy premiums can rewrite inflation constraints

Brent crude rose more than 3% on Thursday, touching above $106 a barrel during the session. The trigger was a statement by Yahya Rahim Safawi, military advisor to Iran's Supreme Leader. He stated that the conflict had spread from the Persian Gulf and the Strait of Hormuz to the Red Sea, and that "if further attacks occur, the battle line could extend to the Indian Ocean and even further." The Indian Ocean shipping routes connect energy exports with demand in Asia and Europe. If transportation and insurance costs rise, the risk premium for crude oil will be transmitted from the spot market to inflation expectations, and then to real interest rates. The significance of high energy prices lies not in single-day increases, but in how they pin central bank reaction functions to the price side. High oil prices increase imported costs, weakening the explanatory power of "price fluctuations being merely temporary disturbances"; the interest rate market absorbs this constraint through interest rate hikes, while the long-term market absorbs the dual uncertainties of fiscal policy and inflation through term premiums. These three chains follow the same macroeconomic logic: conflict disrupts supply, supply disrupts prices, and prices disrupt the discount rate. As long as the risks associated with shipping routes are not explicitly dismantled, the transmission of crude oil's impact on interest rates will not disappear from the pricing table.

Frequently Asked Questions

Question 1: What does the rise in the US 30-year Treasury yield to 5.44% signify? Answer: It records the re-incorporation of term premium and supply premium into prices. With funds locked up for 30 years, it's necessary to cover inflation uncertainty, issuance size, and refinancing risks. This level reflects the fact that financing costs and discount rates have already increased. Question 2: Why are crude oil and Treasury yields rising simultaneously? Answer: Energy prices are rewriting real interest rates and policy paths through inflation expectations. If the Middle East conflict spills over to Indian Ocean shipping routes, increased transportation and insurance costs will lengthen price stickiness. The interest rate market is pricing in this constraint through interest rate hikes; both are at opposite ends of the same macroeconomic logic, not two unrelated events.
