Argentina has threatened sanctions against companies exploring for oil near the Falkland Islands, sending shares in Falklands-focused oil explorers sharply lower. The move revives long-running tensions between the UK and Argentina over sovereignty and resource rights in the South Atlantic, adding fresh risk for firms operating in the disputed waters.

Elsewhere in the day's business news, UK car sales reached their highest level in eight years, offering a bright spot for the domestic economy, while attention also turned to US monetary policy after strong American jobs figures. Donald Trump used a Truth Social post to demand the Federal Reserve cut interest rates, citing August's 162,000 new jobs as evidence of a stronger US economy, and threatened to halt trade with countries running surpluses with the US if rates were not lowered. However, new Fed figure Kevin Warsh reportedly views building inflationary pressures as a reason to consider raising rates rather than cutting them, setting up a potential clash over policy direction.
