The new tariff takes effect against a backdrop of significant global stock market declines and diplomatic discussions amid rising trade tensions.
Donald Trump's 10% tariff on UK products officially came into effect on Saturday, leading to considerable turmoil in global stock markets.
Following the announcement, major indices experienced steep declines, reflecting investor concerns over potential repercussions in global trade.
The London Stock Exchange's FTSE 100 index suffered its worst trading day since the onset of the
COVID-19 pandemic, plummeting by 419.75 points, or 4.95%, to close at 8,054.98 on Friday.
This marked the largest single-day loss since March 2020. Similarly, the Dow Jones Industrial Average fell by 5.5% on the same day as reactions to the tariff announcement spread beyond the UK.
In Australia, the stock market fell by 191.90 points (2.44%) upon closing, hitting a 100-day low.
The Italian market also experienced a significant drop, closing down 6.5%.
The imposition of these tariffs follows a broader new framework of US tariffs affecting various imported goods.
In addition to the 10% tariff on UK imports, a 25% tariff on all foreign cars entering the US took effect on Thursday.
Other countries, including those in the European Union, are set to face even steeper tariffs.
The EU, for example, will see a 20% rate applied to its imports under the new policy.
The tariffs were formally enacted shortly after 5 AM UK time on Saturday, following President Trump's announcement earlier in the week.
In response, China announced intentions to impose a retaliatory 34% tariff on all US imports, effective from April 10.
Prime Minister Sir Keir Starmer engaged in discussions with foreign leaders over the weekend concerning the tariff situation.
He spoke to Prime Ministers Anthony Albanese of Australia and Giorgia Meloni of Italy, both of whom concurred that a full-scale trade war would be detrimental to all involved nations.
Downing Street indicated that the UK’s strategic response would prioritize national interests, with officials focusing on preparing for potential countermeasures rather than hasty reactions.
Amid the ongoing situation, the UK government has drawn up a potential list of products subject to retaliation and is consulting with businesses to assess the implications of any counteractions.
Chancellor Rachel Reeves emphasized the government’s commitment to securing advantageous trade agreements with the US, stating that the aim is to protect British jobs and industries from the effects of escalating tariffs.
The government remains cautious, seeking to avoid direct criticism of the US administration while simultaneously negotiating for potential exemptions from such tariffs.
Opposition parties have criticized the Government's approach, arguing that efforts to appease the Trump administration have been ineffective.
The Liberal Democrats called for a collaborative response involving European and Commonwealth allies to mitigate the impact of the tariffs on the UK economy.
President Trump, in a social media post, encouraged US businesses to remain resilient, asserting that tariffs are a permanent aspect of the economic landscape and suggesting that achieving a favorable trade deal would benefit the US economy in the long term.
