America's "Hottest Economy" Runs on AI and Borrowed Time

President Trump says his economy is the envy of the world, but the figures reveal strong growth shadowed by rising prices.

When a president tells voters that his country is "the hottest anywhere in the world", the claim can be tested against a thermometer. For Donald Trump, ahead of the midterm elections, the readings are mixed: some are genuinely high, while others burn the people he is trying to reassure. Start with the good news. The US economy is expanding at an annualised rate of 2.

2%, and it has grown by about 3.2% since the end of 2024, more than any other G7 member over the same period. That outcome beat expectations. After the "Liberation Day" tariffs of 2 April 2025, the International Monetary Fund cut its forecasts, warning that import duties would damage investment and consumer spending.

Trump then softened many of the tariffs in the following months, which reduced the expected harm. The second explanation is less comfortable. American technology companies have poured money into artificial intelligence, and spending on data-centre construction, excluding the computer hardware inside, reached $5bn in August 2026. That is almost double the monthly rate when Trump returned to office.

Growth that leans so heavily on one sector is vulnerable: if the investment were to dry up, the economy could falter. Meanwhile, households are feeling something different.

French Unrest Pushes Borrowing Costs Toward 24-Year High

On Monday, the yield on France's 10-year bond jumped as much as 16 basis points to 4.94%, its highest level in almost a quarter-century, after a weekend of riots and 2,400 arrests. The spread over German bunds approached a 14-year peak. Goldman Sachs argues that France's fiscal problems now look harder than during the 2011-15 eurozone crisis, even if disorderly contagion seems less likely.…

Microsoft Exits Nscale's £2bn Essex AI Project

A £2bn pledge, a promised supercomputer, and now a missing anchor customer: Nscale's planned AI data centre in Loughton, Essex, has lost Microsoft, which was to fund the machine. The BBC understands the American giant has ended its involvement. Nscale insists the UK's largest such facility will still be built, and says it is exploring alternative power sources. Electricity, not capital, may be the real constraint.…

IIGRAMMAR FOCUS
Participle clauses — present (-ing) and past (-ed)
A present participle (-ing) clause describes an active action or result by the same subject, while a past participle (-ed) clause has a passive meaning and describes something done to the subject. Both can replace a longer clause with 'and', 'because' or 'which', and they must share the subject of the main clause.

  4. Microsoft, its involvement in the project, has left Nscale without an anchor customer.
  5. Households, with inflation of 3.7%, may not feel the benefit of strong national growth.
  6. about contagion, investors demanded a higher return for holding French debt.
IIIDEPENDENT PREPOSITIONS
Complete each phrase with the correct preposition. All from today’s articles.
  1. The expansion leans heavily ___ a single sector.
  2. Many voters punished Biden ___ the post-pandemic price spike.
  3. The IMF warned ___ the damage that import duties could do to investment.
  4. The yield jumped ___ a weekend of riots and 2,400 arrests.

IVCRITICAL THINKING
Both the American and French stories involve governments that depend on investors' confidence, whether in an AI boom or in the bond market. Who ultimately holds more power over a country's economic direction: elected leaders, or the markets and corporations that finance them? Consider the Microsoft withdrawal from Essex as a further example, and use specific evidence from the articles to support your view.
