Sharecast - At 0855 BST, the FTSE 100 flat at 7,445.04.
Richard Hunter, head of markets at Interactive Investor, said: "The spectre of interest rate rises which may have further to run has stalled progress over the last few trading sessions, and the latest economic news from the US in particular has strengthened the possibility.
"Lower than expected jobless claims suggest that the labour market remains resilient despite the rate hikes so far. In addition, a further rise in labour costs and a recent spike in energy prices are increasing the difficulties of getting the inflation genie back into the bottle. As such, the Federal Reserve may consider that it has leeway to raise rates once more towards the end of the year. Its insistence that it will remain data dependent, when the data coming through is strong, has left investors who were hoping for imminent rate cuts high and dry."
Hunter also pointed to renewed tensions between China and the US, "with the reported ban on iPhone use by state employees and wider protectionist fears in both directions weighing on sentiment".
In equity markets, JD Sports jumped to the top of the FTSE 100 after Berenberg lifted its price target on the shares to 225p from 210p and said investors still underappreciate the strength of the company’s model, its positioning and the international opportunity.
Next was also in the black after an upgrade to ‘buy’ from ‘hold’ at Societe Generale (EPA:SOGN).
Computacenter (LON:CCC) surged as its first-half revenues and pre-tax profit came in ahead of expectations.
Housebuilder Berkeley was little changed after it reaffirmed full-year earnings guidance but said private sales reservations were down 35% due to rising interest rates and political volatility.
On the downside, Petershill Partners slumped after the investment firm cut its full-year guidance.
