The Weekly Market Update

29 August to 4 September 2026

One thing ran through everything this week: the price of energy.

Fighting between the United States and Iran started up again, oil had its best week since July, and the price of diesel in America hit an all time record. Inflation in Europe jumped to its highest level this year, almost entirely because of energy bills. And in America, a much stronger than expected jobs report landed on top of all of it.

The result is a genuine shift. Central banks that spent the last two years cutting interest rates are now being pushed towards raising them. That is happening in America, in Europe and in Britain at the same time.

Markets at a glance

Figures as at the close on Friday 4 September 2026. The Week column is measured from the previous Friday’s close, 28 August 2026. Yearly changes are the 12 month change from Trading Economics. For interest rates and bond yields, both change columns are shown in percentage points, so a move from 4.72% to 4.79% is +0.07 points. A bond yield is simply the yearly return a lender earns for lending money to the government, and it rises when the price of the bond falls. Green means the number went up, red means it went down, whatever that means for your wallet.

01 · Markets & Rates

America added three times more jobs than expected, and a rate rise moved back into view

What happened. American employers added 162,000 jobs in August. Economists had expected somewhere around 55,000. The unemployment rate stayed at 4.1%, average pay rose 3.1% over the year to $37.75 an hour, and the June and July figures were revised up by 55,000 between them. Restaurants and bars alone added 59,000 jobs. Traders quickly moved to price in a Federal Reserve rate rise this month, with the implied chance rising to about 60% from roughly 49% the day before. Shares fell on the news, with the S&P 500 closing down 0.4% on Friday.

Why it matters. Normally a strong jobs report is cheerful news. Right now it is not, because inflation in America is still running well above the 2% the Federal Reserve aims for, and its new chair Kevin Warsh said only last week that the Fed “has more work to do”. A jobs market this healthy removes the main argument for leaving rates alone. Higher official rates feed through to mortgages, car loans and credit cards.

What to watch. American inflation figures are published this coming week, and the Federal Reserve meets on 15 and 16 September. As Ellen Zentner of Morgan Stanley Wealth Management put it, the decision “is in the hands of next week’s inflation numbers”.

02 · Geopolitics & Energy

Fighting with Iran restarted, and American diesel hit an all time record

What happened. After a few quiet weeks, the United States and Iran traded blows again. On 30 August American forces hit Iranian rocket launchers near the Strait of Hormuz, the narrow sea passage that a large share of the world’s oil sails through. On 1 September the United States struck two Iranian government oil tankers as part of a wave of attacks on around 100 targets, the first time it had gone after tankers in response to Iranian attacks on commercial shipping. Iran fired roughly 25 ballistic missiles and a batch of drones at American bases in Jordan, Bahrain, Kuwait and Iraq, and most were shot down. Brent crude oil finished the week at $95.52 a barrel, up 7.6%, its best week since mid July. In America the average price of diesel reached $5.85 a gallon, beating the $5.81 record set in June 2022.

Why it matters. Diesel is the fuel that moves things. Roughly three quarters of farm machinery and about nine in ten of America’s 500,000 school buses run on it, along with most lorries and freight trains. When diesel goes up, the cost of delivering food, parcels and building materials goes up a few weeks later. That is one of the reasons inflation is proving so hard to shake, and why central banks are talking about raising rates rather than cutting them.

What to watch. OPEC+, the group of major oil producing countries, meets on Sunday 6 September and was widely expected to leave its output plans unchanged. If it does, there is no extra supply coming to take the pressure off prices.

03 · AI & Technology

Nvidia is buying Hugging Face, the public library of free AI models, for $12.9bn

What happened. On 3 September Nvidia confirmed it is buying Hugging Face for $12.93bn. Hugging Face is not a household name, but it is where a very large part of the AI world actually works. Founded in 2016, it hosts around 3 million ready made AI models, a million apps and 500,000 collections of training data, free to download, and it is used by more than 18 million software developers. It brings in about $150m a year.

Why it matters. Nvidia already makes the chips that almost all AI runs on. Buying Hugging Face means it also owns the shop where developers go to pick up the software. Paying nearly 13 billion dollars for a business with 150 million dollars of sales is not a bet on that revenue. It is a bet on owning the place where the next generation of AI builders starts work, and on selling them spare computing power once they are there.

What to watch. Whether it stays genuinely open. Nvidia’s chief executive Jensen Huang promised that “Nvidia compute will not be required to build on or deploy through Hugging Face”. Rival chipmakers and competition regulators will be checking that promise closely.

04 · Business & Economy

Europe’s inflation jumped to a 2026 high, and its central bank is expected to raise rates

What happened. Figures published on 1 September showed prices across the twenty countries that use the euro were 3.3% higher than a year earlier, up from 2.9% in July and the highest reading of 2026. Almost all of the increase came from energy, which was 14.3% dearer than a year ago, against 10.3% the month before. Strip out energy and food and the underlying rate actually fell slightly, to 2.4%. All 65 economists in a Reuters survey now expect the European Central Bank to raise its main rate by a quarter of a percentage point, from 2.25% to 2.50%, on 10 September.

Why it matters. This is the same story as America and Britain, from a different starting point. Europe’s underlying price pressures are calm. Its energy bills are not. Central banks worry that if expensive energy lasts long enough, workers ask for bigger pay rises and shops put through bigger price rises, and the problem stops being about oil and starts being about everything.

What to watch. The decision on 10 September, and more importantly the language around it. Most economists in that survey think this will be the last increase of the cycle. If the bank hints otherwise, borrowing costs across Europe move again.

Britain’s borrowing costs hit 19 year highs, and investors started betting on rate rises

What happened. The interest rate the British government pays to borrow rose sharply early in the week. The 30 year gilt yield reached about 5.87% on 3 September and the 10 year touched its highest level in 19 years before easing back to 5.13% by Friday. Gilts are simply loans to the UK government, and the yield is what it costs the government to borrow. Investors moved to price in three Bank of England rate rises over the next two years, in November, February and June, which would take Bank Rate from 3.75% to about 4.5%. The Bank’s chief economist Huw Pill argued that raising rates now could reduce the risk of having to tighten much harder later.

Why it matters. Two things follow from higher gilt yields. Fixed rate mortgages are priced off them, so the deals available to remortgagers get more expensive well before the Bank of England does anything. And the government pays more interest on its debt, which analysts reckon has cut its room for manoeuvre before it breaks its own borrowing rules to roughly £13bn from about £22.7bn. That usually means higher taxes, lower spending, or both.

What to watch. The Bank of England’s next decision is on 17 September. Just a week ago the debate was about when rates would be cut. If any policymaker votes for a rise, that debate is over.

Also worth knowing

Broadcom’s AI chip sales more than tripled and the shares fell anyway. The chipmaker reported on 2 September that quarterly revenue rose 86% to $29.6bn, with AI chip sales up 221% to $16.7bn. But its forecast for this quarter, $34.8bn, came in just under the roughly $35bn investors wanted, and the stock closed down 2.75% at $357.16 the next day. When expectations are this high, beating them is not enough.

UK house prices are creeping, not moving. Nationwide reported on 1 September that prices rose 0.2% in August and 1.6% over the year, to an average of £275,465. Its chief economist Robert Gardner blamed subdued activity on energy prices and market interest rates, the same two things driving everything else this week.

Gold slipped and bitcoin went almost nowhere. Gold ended the week at $4,432 an ounce, down 0.5%, as the strong jobs report lifted the dollar. Bitcoin finished around $79,700, up 0.7% on the week and still a long way below its record of roughly $126,000 set last October.
