FTSE 100 Declines as AstraZeneca Weighs on Market Ahead of Central Bank Meetings

Market Overview and Central Bank Expectations

(Reuters) - London's FTSE 100 index slipped on Monday, dragged down by heavyweight AstraZeneca and a stronger pound, as investors braced for a busy week of central bank meetings, including the Bank of England.

Impact of AstraZeneca on FTSE 100

The blue-chip FTSE 100 closed down 0.1%, while the midcap FTSE 250 index edged up 0.1%

Pound's Performance Against the Dollar

AstraZeneca fell 3.2% after Handelsbanken cut its rating and Reuters reported the drugmaker had paused a planned £200 million ($271.26 million) investment in its Cambridge research site.

Other Notable Stock Movements

The BoE is expected to hold interest rates steady on Thursday amid rising inflation and to slow its £100 billion‑a‑year bond unwind amid renewed gilt‑market volatility. A Reuters poll shows most economists expect one rate cut next quarter and another early next year.

The pound rose to its highest level since early July against the dollar. It was last up 0.4% at $1.36.

The spotlight remains on the U.S. Federal Reserve, which sets policy this week, alongside central banks in Japan and Canada.

Additionally, the U.S. and Britain will announce agreements on technology and civil nuclear energy during President Donald Trump's second state visit this week, as the UK seeks to finalise steel tariffs under a much‑anticipated trade deal.

Among other stocks, AO World jumped 14% after the British electronics retailer laid out plans for its first-ever share buyback and raised the lower end of its annual adjusted pre-tax profit forecast.

Sainsbury hit a more than four-year high, up 3.5%, after the supermarket group said it had terminated talks with Chinese e-commerce giant JD.com over selling the Argos general merchandise retailer.

Martin Sorrell's advertising group S4 Capital slumped 21% to a record low after cutting its annual revenue forecast for the second time this year.
