A sharp selloff in global bond markets deepened on Wednesday as oil prices surged, fiscal concerns mounted in major economies and geopolitical risks fueled investor unease.
Ten-year government bond yields in Japan climbed above 3% for the first time in three decades, while German Bund yields reached their highest level since 2011 and British gilts hit levels not seen since 2008. In the United States, the 10-year Treasury yield hovered near 19-year highs at 4.7961%, with the two-year yield also elevated near an 18-month peak of 4.3897%. Brent crude oil traded at a one-month high of $95.09, up 0.46%.
Analysts attributed the rout to a confluence of factors, including sustained upward pressure on energy prices driven by Middle East tensions, rising concerns over public debt levels in Europe and Japan, and increased issuance by major technology firms seeking capital for artificial intelligence infrastructure. The selloff has been described as "orderly" by some market participants, though it reflects broader anxieties over fiscal sustainability.
In Japan, Prime Minister Sanae Takaichi faces pressure as the country grapples with its first sub-1% 10-year yield in three decades. Nomura Securities chief macro strategist Naka Matsuzawa noted that the move above 3% marks a significant shift in global borrowing costs. Meanwhile, in Europe, natural gas prices have surged to their highest since early 2023, compounding inflationary pressures.
In the United States, Federal Reserve Chair Kevin Warsh has emphasized price stability as the central bank's priority, downplaying labor market concerns despite a steady decline in monthly nonfarm payrolls since March. Traders are pricing in roughly a 70% probability of a rate hike following the upcoming European Central Bank meeting, though upcoming U.S. jobs data may have diminished impact compared to inflation readings.
Fiscal policy remains a key flashpoint. Britain's new government, led by Prime Minister Andy Burnham, is scheduled to present its budget in October, while France is bracing for contentious debates over its next fiscal plan. State Street's head of macro strategy Michael Metcalfe highlighted the lack of positive catalysts, citing looming budget announcements in Europe as a potential catalyst for further volatility.
Yardeni Research's Ed Yardeni, who coined the term "bond vigilantes" in the 1980s, warned that rising deficits risk driving yields higher unless policymakers take action. He suggested that if U.S. 10-year yields breach 5%, Treasury Secretary Scott Bessent could respond by issuing shorter-dated debt to buy back longer-dated bonds.
The selloff has also been exacerbated by increased bond issuance from major technology firms, or "hyperscalers," as they raise capital to fund AI expansion. This competition for investor capital has intensified pressure on sovereign debt markets already strained by fiscal deficits and geopolitical risks.
Market strategists at Saxo and Vantage Point Asset Management in Singapore echoed concerns over the sustainability of current yield levels, with Saxo's Charu Chanana warning that the combination of energy inflation, fiscal imbalances and geopolitical instability creates a challenging backdrop for fixed income investors.
