The FTSE 100 edged lower on Monday despite stronger European and US markets, as a sharp sell-off in **AstraZeneca** overshadowed improving investor sentiment driven by easing Middle East tensions and a retreat in oil prices.

The blue-chip index closed **10.35 points lower (-0.1%) at 10,857.70**, while the **FTSE 250** climbed **1.0% to 24,224.77** and the **AIM All-Share** gained **0.8% to 768.61**.

AstraZeneca, the index’s second-largest constituent, slumped **9%** after reports it had held merger discussions with US pharmaceutical giant **Bristol-Myers Squibb** over a potential **US$400 billion** deal. Investors questioned the strategic rationale, with analysts suggesting the move could signal uncertainty over AstraZeneca’s long-term growth pipeline.

Broader market sentiment improved after **Brent crude** fell to around **US$83.90 a barrel**, following comments from US President Donald Trump indicating he was delaying further military action against Iran in favour of renewed diplomatic efforts. The decline in oil prices eased inflation concerns and supported expectations for lower bond yields.

Lower yields helped rate-sensitive sectors, with UK housebuilders among the strongest performers. **Barratt Redrow** rose **3.8%**, **Persimmon** added **2.2%**, and **Vistry** jumped **8.0%**.

On the FTSE 250, shipping services group **Clarkson** surged **9%** after upgrading full-year guidance, citing exceptional first-half trading driven by disruption to global shipping routes through the Strait of Hormuz.

In the US, markets traded firmly higher, with the **Dow Jones** up **1.0%**, the **S&P 500** gaining **1.1%**, and the **Nasdaq** advancing **1.8%** as lower energy prices boosted risk appetite.

Investors now turn their attention to Tuesday’s earnings from **BP**, **HSBC** and **Smith & Nephew**, alongside US trade and labour market data.
