Mixed week in America as Altman and Powell spark varying market reactions
An interview with OpenAI chief Sam Altmann raised question marks about the pace of AI investments and sparked an equity sell-off last week. While comparing the current dynamic to the dot-com bubble, Altmann said, “Are we in a phase where investors are overexcited about AI. My opinion is yes. Is AI the most important thing to happen in a very long time? My opinion is also yes.” Before going on to add, “When bubbles happen, smart people get overexcited about a kernel of Truth”. US markets, particularly the NASDAQ, fell in response but did bounce back on Friday following a speech by Fed Chair, Jerome Powell.
Powell gave a major boost to the prospects of an interest rate cut in September saying, “the shifting balance of risks may warrant adjusting our policy stance”. Last week’s round of US jobless numbers was higher than expected, up 11,000 from the week before, adding more weight to cutting rates to help businesses borrow.
Any attempts to boost growth via rate cuts will have to be weighed up against inflation, but Powell was more optimistic than expected on the impact of Trump’s tariffs. Powell noted the effects on prices were now “clearly visible” and that there was a reasonable case to be made that any price rises might be “relatively short-lived”.

UK inflation and government borrowing on the rise
UK inflation is now at nearly double the Bank of England’s (BoE) 2% target. Figures for July show the UK Consumer Price Index (CPI) at 3.8%. The BoE’s latest forecast expects it to keep climbing and peak at 4% in September. Airfares were up 30.2% as airline firms cashed in on higher summer holiday demand. Food and non-alcoholic beverages were up 4.9% due to increases to the cost of beef, chocolate, coffee and fresh orange juice. Services were up from 4.7% to 5%. As a result, the Retail Price Index (RPI), which includes things like mortgage payments and insurance, also rose from 4.4% to 4.8%.
Unease over UK public finances and the stickiness of inflation sent the UK government’s borrowing costs up sharply with the interest on 30-year UK gilts rising to 5.61% – it’s highest level since May 1998. To put this rate into context, the new rate is nearly a percentage point higher than the level reached during Liz Truss’s mini-budget crisis in October 2022.
German GDP shrinks but manufacturing continues to rise
Last week’s German GDP numbers for Q2 saw Europe’s largest economy shrink by 0.3%. Q1 had been boosted by a surge in economic activity as US businesses front-loaded on German exports before the implementation of Trump’s tariffs. Over the year the German economy is now up 0.2%.
German PMI data bought some good news as it beat expectations and showed activity growing for the third consecutive month. Manufacturing posted its biggest production increase in over three years. In line with other major economies – employment has continued to decline as German firms use the rising output to go after productivity gains rather than capital expansion.
