It is “Liberation Day” III – the third tariff deadline set by Donald Trump.

Countries without bilateral trade agreements will soon face reciprocal tariffs – ranging from 25% to 50% – with a baseline of 15% to 20% for any not making a deal.

He has delayed twice, from April to July and from July to August, but hammered this date home in his trademark caps-on style: “THE AUGUST FIRST DEADLINE STANDS STRONG, AND WILL NOT BE EXTENDED. A BIG DAY FOR AMERICA!!!”

“Will not be extended” for anyone but Mexico, it seems. The country secured a 90-day extension at the last minute, with Mr Trump citing the “complexities” of the border.

By close of business on the eve of deadline, he had a handful of framework deals – some significant – including the UK (10%), the EU, Japan and South Korea (15%), Indonesia and the Philippines (19%), Vietnam (20%).

On the EU agreement, which he struck in Scotland, the president said: “It’s a very powerful deal, it’s a big deal, it’s the biggest of all the deals.”

But what happened to the “90 deals in 90 days” touted by the White House earlier this year?

The short answer is they were replaced by letters of instruction to pay a tariff set by the US.

Amid of flurry of late activity, the US played hardball with major trading partners like Canada.

“For the rest of the world, we’re going to have things done by Friday,” said US Commerce Secretary Howard Lutnick – the “rest of the world” meaning everyone but China.

There is, apparently, the “framework of a deal” between the world’s two largest economies, but talks between Washington and Beijing are continuing.

In terms of wins, he can claim some significant deals and point to his tariffs having generated an impressive $27bn (£20.4bn) in June, not bad for a single month.

But the legality of the approach is under siege – with the US Court of International Trade ruling that the “Liberation Day” tariffs exceeded the president’s authority, with enforcement paused pending appeal.

The deadline has stirred the pot, forcing a handful of deals onto the table. Whether they stick or survive legal scrutiny is far from settled.

But the playbook remains the same – threaten the world with trade chaos, whittle it down, celebrate the wins, and pray no one checks what’s legal.

Microsoft has become only the second publicly traded company after Nvidia to surpass $4 trn (£3.03trn) in market valuation, after registering huge earnings.

On Thursday, shares rose on Wall Street with the S&P 500 and Nasdaq climbing to new record highs.

Stocks in Microsoft jumped after posting better-than-expected results, helped by its Azure cloud computing platform, which is a centrepiece of the company’s artificial intelligence (AI) efforts.

Shares in Facebook and Instagram’s parent company, Meta, also surged after beating sales and profit targets.

Technology giants Apple and Amazon will report their results after Wall Street’s close.

Microsoft first cracked the $1trn (£760bn) mark in April 2019, but its move to $3trn (£2.27trn) took longer than technology giants Nvidia and Apple.

Nvidia tripled its value in just about a year and clinched the $4trn milestone before any other company on 9 July. Apple was last valued at $3.12trn.

In comparison, the biggest UK company by market value is drug manufacturer AstraZeneca, worth $235.97bn (£178.55bn).

Companies ranked by market value (USD), according to tradingview.com

1. Nvidia (US) $4.43trn
2. Microsoft (US) $4trn
3. Apple (US) $3.12trn
4. Amazon (US) $2.47trn
5. Alphabet (US) $2.35trn
6. Meta (US) $1.95trn
7. Saudi Arabian Oil (Saudi Arabia) $1.56trn
8. Broadcom (US) $1.42trn
9. Berkshire Hathaway (US) $1.03trn
10. Tesla (US) $1.02trn
11. Taiwan Semiconductor Manufacturing (Taiwan) $1trn
29. Samsung Electronics (South Korea) $338.06bn
36. Alibaba (China) $284.62bn
52. AstraZeneca (UK) $235.97bn

While sweeping US tariffs had investors worried about tighter business spending, Microsoft’s strong earnings have shown that the company’s books are yet to take a hit.

Microsoft’s multibillion-dollar bet on OpenAI is proving to be a game changer, powering its Office Suite and Azure offerings with cutting-edge AI and fueling the stock to more than double its value since ChatGPT’s late-2022 debut.

On Wednesday, the firm announced Azure sales surpassed $75bn (£56bn) on an annual basis, while Azure revenue jumped 39% in the April-June quarter.

Overall revenue rose 18% to $76.4bn (£57.81bn) over the same period.

It is also forecasting a record $30bn (£22.7bn) in capital spending over the first quarter to meet soaring AI demand..

Food inflation will rise to 6% by the end of the year – posing a “significant challenge” to household budgets in the run-up to Christmas, industry leaders have predicted.

The British Retail Consortium is warning that the chancellor risks “fanning the flames of inflation” if she hikes taxes in the coming budget.

Despite intense price competition between supermarket chains, the BRC has sounded the alarm over the pace of grocery price hikes.

As of this month, food inflation has risen 4% year on year – its highest level since February 2024.

The BRC said this increase is linked to global factors, such as high demand and crop struggles.

Beef, chicken and tea prices are among those that have risen the most this year – but some of the blame is being laid squarely at the chancellor’s door too.

The BRC said it was inevitable that a £7bn burden, through changes to employers’ national insurance contributions and minimum pay rules after last October’s budget, had been partly passed on to customers in the form of higher prices.

It published the results of a survey of retail industry finance chiefs to illustrate its point – that nerves about what Ms Reeves’s second budget could bring were not helping companies invest in either new employment or prices.

Business was promised it would be spared additional pain after it was put on the hook for the bulk of the chancellor’s tax-raising measures last year.

However, speculation is now rife over who will feel the pain this autumn as she juggles a deterioration in the public finances.

A widening black hole is estimated at around £20bn.

The cost of servicing government debt has risen since the last budget, while U-turns on welfare reforms and winter fuel payment cuts have made her job even harder – making further tax-raising measures inevitable.

The survey of chief financial officers for the BRC showed the biggest current fear ahead was for the “tax and regulatory burden”.

Two-thirds of the CFOs predicted further price rises in the coming year, at a time when the headline rate inflation already remains stuck way above the Bank of England’s target of 2%.

It currently stands at 3.6%.

Helen Dickinson, chief executive of the BRC, said: “Retail was squarely in the firing line of the last budget, with the industry hit by £7bn in new costs and taxes.

“Retailers have done everything they can to shield their customers from higher costs, but given their slim margins and the rising cost of employing staff, price rises were inevitable.

“The consequences are now being felt by households as many struggle to cope with the rising cost of their weekly shop.

“It is up to the chancellor to decide whether to fan the flames of inflation, or to support the everyday economy by backing the high street and the local jobs they provide.”

She concluded: “Retail accounts for 5% of the economy yet currently pays 7.4% of business taxes and a whopping 21% of all business rates.

“It is vital the upcoming reforms offer a meaningful reduction in retailers’ rates bill, and ensures no store pays more as a result of the changes.”

The Treasury has been approached for comment.
