  • Global markets faced volatility due to political uncertainty in the UK and geopolitical tensions in the Middle East.
  • The sterling weakened as UK Prime Minister Keir Starmer considered his future, while oil prices rose following Iran's closure of the Strait of Hormuz.
  • Investors are closely watching these developments.

Global markets experienced fluctuations as political uncertainty in the UK and geopolitical tensions in the Middle East influenced investor sentiment. The sterling eased amid reports of UK Prime Minister Keir Starmer considering his political future following Andy Burnham's election victory, while oil prices rose due to Iran's closure of the Strait of Hormuz.

The political landscape in the UK saw a shift as Prime Minister Keir Starmer faced calls to resign after Andy Burnham's decisive election victory. This political uncertainty contributed to a 0.2% drop in the sterling to $1.3210. Meanwhile, U.S. President Donald Trump added to the speculation by posting that Starmer was set to resign.

In the Middle East, tensions escalated as Iran announced the closure of the Strait of Hormuz, a critical passage for global oil shipments. This move led to a rise in Brent crude futures by 1.1% to $81.43 a barrel and U.S. crude firming 2.7% to $78.70 a barrel. The closure overshadowed the first talks between U.S. Vice President JD Vance and Iranian officials under an interim peace deal.

Amid the uncertainty around a potential challenge against the UK PM and what that means for the fiscal outlook, the likelihood is that gilts will remain under selling pressure to start the week.

The Federal Reserve's recent hawkish stance continued to impact global markets, with S&P 500 futures easing 0.5% and Nasdaq futures losing 0.7%. European markets also felt the pressure, with EUROSTOXX 50 futures falling 0.5%, DAX futures dropping 0.3%, and FTSE futures dipping 0.1%.

In Asia, Japan's Nikkei edged up 0.7%, reaching all-time highs, while South Korea's market fell 0.9% after a significant surge last week. MSCI's broadest index of Asia-Pacific shares outside Japan eased 0.4%.

Background

The current geopolitical and political developments highlight the fragility of global markets in the face of uncertainty. The potential for further instability in the UK and the Middle East could have significant implications for investors worldwide.

Looking ahead, market participants will closely monitor developments in the UK political scene and the situation in the Middle East. Additionally, the Federal Reserve's upcoming core inflation gauge release will be pivotal in shaping future monetary policy expectations.
