#### **FTSE 100 on Track for Worst Week of 2025 Amid US Tariff Uncertainty**

The FTSE 100 is set for its worst weekly performance since December, as investor caution persists amid growing uncertainty over US tariffs.

UK stocks declined another 0.6% today, bringing the index close to a 2% drop for the week.

Diageo shares fell as much as 3.1% following backlash from pubs over its decision to increase Guinness draught prices by 4.2% starting in May. Defending the price hike, a Diageo spokesperson stated:

“We have today informed our on-trade customers of a Cost Price Increase (CPI) on Guinness Draught products. Guinness is a high-quality beer that drives footfall for the hospitality sector, and this CPI allows us to sustain investment in and continue growing the Guinness brand.”

Schroders also tumbled by up to 5%, paring some of Thursday’s 12.6% rally, after the asset manager announced plans to cut costs.

Oil giants Shell and BP weighed heavily on the FTSE 100 throughout the week, while defence companies BAE Systems and Rolls-Royce emerged as the top performers, boosted by increasing calls for higher defence spending.

Richard Hunter, head of markets at Interactive Investor, highlighted the impact of trade uncertainty, stating:

“Markets hate uncertainty, and investors are facing it in abundance. The ever-changing tariff stance from the White House is testing patience, as each shift carries different implications for the deeply interconnected global economy.”
