UK shares rise as Trump's tech tariff exemption calms markets

April 14 (Reuters) - UK shares climbed on Monday in broad-based gains after U.S. President Donald Trump exempted smartphones and computers from steep Chinese tariffs, offering investors some relief following weeks of market volatility.

The blue-chip FTSE 100 index .FTSE was up 2% and the midcap index .FTMC gained 2.5%.

The White House unveiled the tariff exemptions on Friday covering 20 categories including smartphones and laptops, as well as semiconductor memory chips and flat panel displays, accounting for 23% of U.S. imports from China.

But Trump on Sunday declared these exemptions temporary and revealed plans to announce new semiconductor tariffs within a week, with smartphone tariffs to follow "soon."

Persistent uncertainty surrounding tariff policies has disrupted global markets recnetly, leading to a roughly 8% drop in the UK's blue-chip index from its record closing high.

On the FTSE 100 index, 95 out of the 100 listed stocks traded in positive territory.

Heavy-weighted bank .FTNMX301010 stocks led the FTSE 100 gains with Standard Chartered STAN.L and Barclays BARC.L each surging 5%.

Bucking the trend, fund manager Ashmore ASHM.L dropped 6.4% after reporting a 5% sequential decline in third-quarter managed assets, due to some large institutional clients redeeming their holdings near the end of the period.
