A sustained selloff in US Treasuries, combined with rising oil prices and escalating geopolitical tensions, is dragging global bond and equity markets lower simultaneously.
The US 30-year Treasury yield climbed to 5.32%, marking its highest level since June 2007. Meanwhile, Japan's 30-year government bond yield rose 6 basis points to 4.135%. Adding to the pressure, Trump stated he has no intention of extending the soon-to-expire US-Iran agreement, reigniting tensions in the Middle East. Oil prices moved higher on the news, intensifying concerns that inflation will remain persistently elevated.
Asian equity markets are broadly lower, with the MSCI Asia-Pacific index dropping 0.8%. Japan's Nikkei 225 fell 2%, South Korea's KOSPI widened its decline to 2%, and Samsung Electronics slid over 2%. Futures also pointed to weakness in the West, with the Nasdaq 100 futures down 0.7% and Europe's Stoxx 50 futures losing 0.14%.
Yardeni Research has warned that investor anxiety over rising government debt is intensifying. The firm highlights growing scrutiny of the surge in borrowing by hyperscalers and questions whether the Federal Reserve can maintain sufficient inflation vigilance if oil prices climb again.
Where the pressure points are
The Nikkei 225's 2% drop and the KOSPI's 2% decline, with Samsung Electronics falling more than 2%, underscore the regional selloff.
Nasdaq 100 futures are down 0.7%, while European Stoxx 50 futures have slipped 0.14%. The US dollar staged a modest rebound after hitting its lowest level since May on Monday.
The US 10-year Treasury yield edged up 1 basis point to 4.73%, extending the previous session's 3-basis-point gain. Japan's 30-year yield rose 6 basis points to 4.135%, while its 5-year yield continued its downtrend, losing 2 basis points to 2.14%.
Brent crude, the global benchmark, advanced 0.6% to $91.45 per barrel. Gold retreated 0.6% to around $4,390 per ounce, and spot silver slipped below $65 per ounce, falling over 1% intraday.
Bond market strain: long-end yields push higher
The US Treasury selloff persists, driven by sharply expanding government spending, a significant increase in long-dated bond issuance, and inflation running above the Fed's target for the past five years. The 10-year yield rose 1 basis point to 4.73%, building on the prior session's gain.
Even though two moderate inflation readings this month have somewhat tempered market bets on a September Fed rate hike, traders remain vigilant in their scrutiny of the bond market.
Global bond markets are weakening in tandem. Australian and New Zealand bond prices fell, Japan's 10-year yield reached multi-decade highs, French borrowing costs hit their highest since 2008, German yields of similar tenor sit at 2011 levels, UK yields are approaching 6%, and Japanese yields are near historic peaks.
Padhraic Garvey, head of Americas research at ING Group, noted in a report: "US Treasuries continue to trade with a heavy tone, with more pressure likely ahead. The net direction of yields remains upward, particularly at the long end."
Middle East tensions reignite inflation worries
Rising oil prices are another key trigger for the current market turmoil. Trump's indication that he won't extend the expiring US-Iran agreement, coupled with renewed conflict in Lebanon, has dimmed peace prospects and stoked fears that sustained geopolitical tensions will threaten supply. Brent crude rose 0.6% to $91.45 per barrel.
The deteriorating situation in the Middle East also casts doubt on the reopening of the Strait of Hormuz, heightening vigilance over a potential second wave of inflation. Nick Twidale, chief market analyst at AT Global Markets, commented: "The combination of high oil prices, rising Treasury yields, and renewed geopolitical risk is likely to keep volatility elevated, and traders will remain highly sensitive to any new developments in the Middle East."
Market sentiment: debt outlook draws 'bond vigilante' focus
Yardeni Research cautions that investor unease over escalating government debt is building. The strategist team led by Ed Yardeni noted in a Tuesday report that markets are increasingly focused on the surge in borrowing by hyperscalers and questioning whether the Fed can sustain enough inflation vigilance if oil prices move higher.
"We haven't hit the panic button yet," the report stated, "but we're closely watching whether bond vigilantes will take action."
Bloomberg strategist Mark Cranfield added that sentiment across Asian equities is clearly negative, with the early-session disappearance of gains in South Korea's KOSPI serving as a telling example. "The spillover effects from the oil market continue to fuel inflation pressures and push long-term Treasury yields higher, which is the bigger concern for equities."
In other moves, the US dollar rebounded modestly after touching its lowest level since May on Monday, while gold slipped 0.6% to approximately $4,390 per ounce.
