Behind the U.S. Treasury yield breaching 5% lies the combined impact of soaring oil prices, expanding government debt, and an AI‑related financing boom. JPMorgan warns that if yields rise to 5.25%, equity markets will "clearly struggle to absorb" the move. Market attention is focused on the Federal Reserve's decision Wednesday, with the probability of a rate hike now exceeding 90%; analysts expect the 10-year yield could climb further toward 5.5%.
U.S. 10-year Treasury yields have surged past the 5% threshold, reaching their highest level in nearly two decades, as global bond markets grapple with the combined pressures of soaring oil prices, expanding government debt, and a boom in AI‑related financing. This landmark move has not only sent Asian equity and bond markets lower in tandem but has also drawn market attention to the Federal Reserve's interest-rate decision on Wednesday—a pivotal moment that could shape the trajectory of the bond market.
On Tuesday, the yield on the U.S. 10-year Treasury note rose as much as 4 basis points to 5.027%, surpassing its 2023 peak and marking the first time it has reached this level since 2007. The immediate catalyst for this rally was a surge in global oil prices—Brent crude climbed 1.6% to around $107.30 per barrel—as a key Saudi oil pipeline remains offline following an attack, keeping supply risks in the Middle East elevated.
Meanwhile, Japan's 30-year government bond yield rose by 5.5 basis points to 4.12%, and Australia's 10-year bond yield surged by 9 basis points to 5.42%, as the global bond sell-off has lost all clear boundaries. The turmoil in the bond market has quickly spread to other asset classes. Asian equities fell across the board, with the Japanese Topix down 0.7% and the South Korean KOSPI at one point dropping more than 1.5% during trading; Australia's ASX 200 slipped 1%. U.S. stock futures also weakened in tandem, with S&P 500 futures falling 0.3%.
In addition to bond-market pressures, controversy over AI regulation is also weighing on market sentiment. Global stock markets broadly declined on Monday after leading AI companies issued warnings—several AI developers have called for a slower pace of technological advancement to prevent AI from spiraling out of control and causing catastrophic harm. U.S. President Trump promptly criticized the CEO of Anthropic for this stance, further intensifying policy divisions surrounding AI regulation.
Berenberg strategist Chris Armstrong said, "The market is already quite tense; if major players start signaling that they need to hit the brakes, it will only exacerbate uncertainty."
Triple pressures are driving a sell-off in the bond market.
This round of global bond-market sell-offs is not attributable to a single factor, but rather the result of multiple structural pressures叠加.
According to Bloomberg, since the United States launched military operations against Iran at the end of February this year, oil and gas supplies in the Middle East have remained disrupted, driving global bond yields steadily higher. Rising oil prices have directly bolstered inflation expectations, prompting bond investors to demand higher yields as compensation.
Meanwhile, as firms take on large amounts of debt to finance their AI-related expenditures, they are both injecting substantial debt supply into the market and further boosting an already robust U.S. economy, creating a doubly adverse dynamic characterized by "increased supply and constrained demand."
Government debt issuance across countries continues to expand—both to refinance maturing bonds and to finance fiscal deficits—while major central banks have phased out quantitative easing bond‑buying programs. As demand from traditional buyers wanes, the market's reliance on price‑sensitive investors has risen markedly.
Phoebe White, head of U.S. rates strategy at UBS Group, stated,
"Given that the real economy shows no signs of weakening and that supply-and-demand dynamics in the U.S. Treasury market differ markedly from those in 2007, there is very limited room for long-term yields to decline. Structural demand for U.S. Treasuries from traditional buyers, such as foreign official investors, has weakened significantly."
Notably, analysts point out that the U.S. 10-year Treasury yield has surpassed 5%, undermining the stock market's valuation framework.
Grace Peters, Global Head of Investment Strategy at JPMorgan Private Bank, stated, "If bond yields rise to 5% or even 5.25%, I believe the stock market will experience significant overcorrection. The 5% level carries significant psychological weight."
Bloomberg market strategist Mark Cranfield notes that the widening divergence between crude oil and gold suggests macro traders may have to contend with a prolonged breakdown in cross-asset‑class correlations. "They are losing confidence in a 'circuit breaker'—a mechanism capable of reining in oil prices and restoring risk appetite in the market."
The Federal Reserve's decision has become the market's focal point.
Wednesday's Federal Reserve interest-rate decision is the biggest source of uncertainty in the market right now. Current pricing by traders indicates that the probability of a rate hike has exceeded 90%.
BMO Capital Markets strategist Vail Hartman said, "If the Federal Reserve holds rates steady this week, it will be extremely difficult to avoid undermining its credibility in fighting inflation. The market is not only highly sensitive to unexpected rate pauses but also vulnerable to a 'dovish hike'—one that conveys a more patient stance through the dot plot or press conference."
In a research report, Xiao Cui, Senior Economist at Pictet Wealth Management, noted that Federal Reserve Chair Jerome Powell has already lowered the threshold for raising interest rates at the Jackson Hole symposium. Failure to hike rates this time would undermine institutional credibility and further push up long-term yields.
"Therefore, we expect Warsh to deliver a hawkish signal at the press conference—not to overshoot market expectations for the path of rate hikes, but to reinforce the Fed's commitment to price stability and to anchor long-term yields."
Zach Griffiths, head of investment-grade and macro strategies at CreditSights, said, "There are currently numerous structural factors underpinning the ongoing rise in interest rates—this is the path of least resistance." He expects the 10-year yield could climb further toward 5.5%.
