Good morning and welcome to our ongoing coverage of the business sector, financial markets, and global economic developments.
The market instability that troubled investors yesterday continues, with government borrowing rates worldwide reaching their highest levels in years.
Asian-Pacific stock markets are experiencing declines today, driven by renewed hostilities between the United States and Iran, which are pushing oil prices higher.
In Tokyo, the Nikkei 225 index has fallen by 2.7%. The Chinese markets are also in the negative, with the CSI 300 down by 1.4%, while South Korea’s KOSPI has decreased by 3.3%.
Wall Street also closed lower last night, with the Russell 2000 index, which tracks smaller U.S. firms, dropping by 1.2%.
This downturn follows a tumultuous day in the bond market on Tuesday, where long-term borrowing costs in the UK surged to levels not seen since early 1998, and Japan’s 10-year bond yield reached its highest point since 1996.
Several factors appear to be driving up sovereign bond yields, including concerns over rising inflation, apprehensions regarding government spending, and competition from AI firms that are also significantly increasing their borrowing.
Jim Reid, a market strategist at Deutsche Bank, commented, “As meteorological autumn began yesterday, a chill swept through markets as rising geopolitical tensions, oil prices, and bond yields created a risk-off atmosphere to start September.”
Higher bond yields increase the cost of government borrowing, which could limit the fiscal space for the new UK chancellor, complicating the ability to fulfill new spending commitments in the upcoming budget.
Last night, Lord Jim O’Neill cautioned that UK mortgage rates are set to increase unless the bond market stabilizes. Speaking to LBC’s Andrew Marr, he remarked, “It has been a tough day, with 10-year gilt yields rising by a quarter of a percent, a significant one-day increase we haven’t seen since the days of Liz Truss.” He emphasized that investors are looking for evidence of a “sensible fiscal strategy” from the UK government, adding, “I woke up this morning thinking this is going to be tough, and it has indeed been tough.”
Upcoming economic data includes ONS Mergers and Acquisitions for UK companies from April to June 2026, scheduled for 9:30 AM, followed by US mortgage application statistics at noon BST.
In a news update, UK government borrowing costs have surged at the start of trading as the bond market sell-off continues. The yield on UK 10-year bonds has risen by 4 basis points to 5.268%, marking the highest level since June 2008, according to Reuters.
The yield on 30-year UK bonds also climbed by 5 basis points, nearing 5.89%, close to the peaks observed yesterday. These yield increases, while modest, add to the pressures facing Andy Burnham’s administration, diminishing the “fiscal headroom” available to Chancellor John Healey ahead of the autumn budget.
Market strategist Joel Kruger from LMAX Group stated that the rising oil prices are contributing to the increase in bond yields, noting, “The prevailing theme as markets open is the renewed escalation between the US and Iran, with military and tanker strikes causing concerns about disruptions in the Strait of Hormuz. Oil prices have reached a six-week high, exacerbating inflation worries and resulting in another sharp uptick in global bond yields.”
Chris Beauchamp, chief market analyst at IG, warned that the bond market sell-off shows no signs of abating, stating, “The market rout accelerated yesterday and continues to show no end.”
Governments across the globe are feeling the pressure from rising bond markets, with the UK facing particular challenges as Andy Burnham’s ambitious economic reforms confront the harsh realities of escalating debt levels and soaring borrowing costs. UK taxpayers may find themselves bearing the cost of these grand plans while also facing the likelihood of a Bank of England rate hike linked to rising oil prices.
Budget airline Ryanair has issued a warning that ticket prices could surge next year if oil prices remain elevated. The airline has reduced its passenger traffic forecast from 216 million to 214 million for the current financial year in an effort to mitigate exposure to unhedged winter oil costs. Ryanair also anticipates a significant increase in short-haul airfares across Europe next year, unless crude prices decrease, cautioning that some less-hedged competitors may struggle to survive the winter months.
The head of the International Monetary Fund, Kristalina Georgieva, has highlighted that the increase in bond yields in advanced economies poses a threat to developing nations. Speaking at a G20 meeting of finance ministers and central bank governors in North Carolina, she described the rise in global borrowing costs as a “particular concern.” Georgieva noted, “The sovereign debt situation for emerging and low-income countries had been gradually improving due to domestic policy efforts and international cooperation, but persistent risks and uncertainties in the global economy, including spillovers from the significant rise in yields in advanced economies, necessitate policy discipline and underscore the importance of building economic buffers.”
The global rise in interest rates is particularly alarming, as increasing yields in major advanced economies are elevating yield curves worldwide. In some emerging markets, this trend undermines the progress made in narrowing yield spreads. Many developing economies, especially low-income countries, are facing heightened refinancing needs and escalating debt-service costs, further constraining their financial stability.
