The FTSE 100 made steady progress on Monday ahead of talks between US President Donald Trump, his Ukrainian counterpart Volodymyr Zelensky and European leaders in Washington.

The gathering is a follow-up summit to Mr Trump’s meeting with Russian President Vladimir Putin in Alaska on Friday, which failed to produce a ceasefire in the war in Ukraine.

Michael Brown, senior research strategist at Pepperstone said Friday’s meeting turned out to be a “damp squib”, yielding “nothing by way of concrete progress.”

It “seemed to pretty much be a meeting about having another meeting to arrange more meetings, all while not achieving much,” Mr Brown quipped.

“While Zelensky and Trump will meet today, and that may bear some fruit, I shan’t be holding my breath,” he added.

The FTSE 100 index closed up 18.84 points, 0.2%, at 9,157.74. The FTSE 250 ended down just 8.67 points at 21,749.57 while the AIM All-Share finished 0.59 of a point higher, 0.1%, at 761.16.

In Europe, the CAC 40 in Paris fell 0.6%, while the DAX 40 in Frankfurt closed down 0.2%.

In New York, the Dow Jones Industrial Average was up 0.1%, the S&P 500 was 0.1% lower, and the Nasdaq Composite declined 0.2%.

Investors are also focused on a speech this week by US Federal Reserve chief Jerome Powell at the annual retreat of global central bankers in Jackson Hole, Wyoming.

Markets hope Mr Powell will provide more clues about the Fed’s plans for interest rates when it meets next month, after data last week provided a mixed picture about inflation.

Consumer inflation remained steady last month, but producer prices accelerated.

But JPMorgan said while “highly anticipated, it is useful to recall that several recent Jackson Hole speeches by Fed chairs did not break new ground or send clear policy signals”.

“We don’t think Powell can firmly guide toward easing at the next meeting,” it added.

The pound eased to 1.3517 dollars late on Monday afternoon in London, compared to 1.3566 dollars at the equities close on Friday. The euro dipped to 1.1667 dollars, lower against 1.1712 dollars. Against the yen, the dollar was trading a touch higher at 146.96 yen compared to 146.90 yen.

The yield on the US 10-year Treasury was at 4.35%, widened from 4.31%. The yield on the US 30-year Treasury was 4.95%, stretched from 4.90%.

In the UK, a report showed consumer sentiment improved a little in August, though it remained in negative territory.

The S&P Global UK consumer sentiment index advanced to 47 points in August from 45.1 points in July, still below the neutral 50-point mark.

It was the highest figure since last October’s UK government budget announcement, meaning a 10-month high.

Maryam Baluch, economist at S&P Global Market Intelligence, said: “August CSI data comes hot on the heels of the recent rate cut decision made by the Bank of England earlier in the month. Data collection began just a day after the central bank’s announcement, providing a timely snapshot of sentiment in the wake of monetary policy easing.

“Encouragingly, the data reveals a slight revival in household confidence, which is a telling sign that the easing of monetary policy has been received positively by households across the country. The headline index signalled the strongest reading since last October, greatly bolstered by robust perceptions of labour market conditions, which were the second-strongest in the survey’s history.”

On the FTSE 100, defence stocks Babcock International rose 5.0% and BAE Systems climbed 1.7% amid the Ukraine-Russia uncertainty.

Babcock received an added boost as RBC Capital Markets started coverage with an “outperform” rating and 1,200p per share price target.

The broker flagged Babcock’s strong management team, improved earnings quality and conservative guidance as reasons for upside.

On the FTSE 250, boot maker Dr Martens led the way, up 8.3% as Peel Hunt upgraded to “buy” from “add”.

The broker thinks Dr Martens is making clear progress under new management and believes the shares have not yet factored in the potential for the firm to move back into growth.

But Close Brothers led the fallers, down 3.7% as RBC downgraded to “sector perform” from “outperform” after the strong rally in the wake of the Supreme Court ruling on motor finance.

On AIM, Pantheon Resources leapt 16% after it said results from an appraisal well in Alaska exceeded expectations, highlighting the “enormous potential” in the firm’s portfolio.

Pantheon said the Dubhe-1 pilot hole was successfully drilled, logged and cored to a total measured depth of 12,833 feet.

Analysis of the thickness and quality of the primary target topset confirmed that the SMD-B zone has exceeded the upside pre-drill expectations.

Chief development officer Erich Krumanocker said: “We are delighted to announce the Dubhe-1 pilot hole results as a success. The well confirms the presence and quality of the oil and gas reservoirs in the Ahpun field, exceeding our pre-drill expectations.”

A barrel of Brent fell to 66.07 dollars late Monday afternoon from 66.33 dollars on Friday. Gold ebbed to 3,334.83 dollars an ounce against 3,343.39 dollars.
