Fresh tensions in the Middle East have influenced global markets, as oil prices surged and bond yields displayed volatility on Monday. The international benchmark for oil, Brent crude, saw its price increase following an attack on a nuclear power plant in the United Arab Emirates. This incident coincided with faltering peace talks between the US and Iran, now in their sixth week of a ceasefire. Former President Donald Trump contributed to the tensions by issuing a social media warning to Iran, stating, “For Iran, the Clock is Ticking, and they better get moving, FAST, or there won’t be anything left of them. TIME IS OF THE ESSENCE!”
As a result, Brent crude rose by up to 1.77%, reaching $111.16 a barrel, marking its highest point in nearly two weeks. However, the price settled back to $110 a barrel after Iran indicated it had responded to a new US proposal aimed at resolving the conflict. Iran’s foreign ministry spokesperson, Esmaeil Baqaei, confirmed ongoing exchanges through a Pakistani mediator, though details were scarce.
Global bond markets experienced fluctuations, with the benchmark 10-year US Treasury yield climbing to 4.631%, its highest since February 2025, before adjusting back to 4.599%. In the UK, the 10-year gilt yield reached 5.19%, surpassing an 18-year high before retreating to 5.15%. The volatility in UK government bonds is partly attributed to political uncertainty, with speculation that Prime Minister Keir Starmer might face a leadership challenge from Manchester Mayor Andy Burnham later this year. As UK Chancellor Rachel Reeves and other G7 finance ministers convened in Paris to discuss the economic impacts of the Middle East conflict, the potential for a shift to the left in UK politics has also raised concerns among investors.
Market analysts have weighed in on these developments. Mohit Kumar, chief economist at Jefferies, noted that bond investors are worried about the implications of increased public spending if the UK government shifts leftward, given the already strained fiscal landscape. Kathleen Brooks, research director at XTB, suggested that UK bond yields might recover if markets perceive a moderation in Burnham’s spending plans. She pointed out that the critical test for the UK markets is whether the 10-year yield can dip below 5% and if the 30-year yield can pull back from highs last seen in 1998.
In Asia, bond yields followed a similar upward trajectory, with Japan’s 10-year yield reaching an almost 30-year high of 2.8% as the government prepared to issue new debt to mitigate the economic impact of the Middle East conflict. Meanwhile, European stock markets opened lower, with the Stoxx Europe 600 dropping by 0.7%, and the UK’s FTSE 100 remaining largely unchanged. In Asia, Japan’s Nikkei and Hong Kong’s Hang Seng index both fell by about 1%, while Shanghai’s SSE Composite saw a modest decline of 0.1%. South Korea’s Kospi, however, edged up by 0.3%.
