It's the call of the wild: much market focus will be on what emerges from Wyoming, today and tomorrow. Global central bankers meet in Jackson Hole, including US Federal Reserve chair Janet Yellen and European Central Bank boss Mario Draghi. Expect much talk around job creation, inequality and financial stability.

How much clarity is given on the unwinding of cheap money, or QE, is the biggest question of all. Around these issues is worry about US Republican deregulation of the banking sector. Either way, explicit and not so explicit risk links will be scrutinised. Friday night is when Draghi makes a key market-moving speech – the subject of QE or ‘tapering’ can’t be avoided. 

Today, second quarter UK GDP numbers, including investment and consumer spending detail, emerge from the Office of National Statistics. A reading of 0.3% is expected. Overnight, more pressure on sterling, down -0.14% to $1.2780 while the euro was at $1.1798 (7am).

Dixons Carphone worries on profits

We start with a nip into Dixons Carphone, owner of Currys and PC World. Though Q1 Group revenues rise 6%, with stronger sales from the Nordics and Greece in particular (up 17% and 16%), there's a nasty profit lurch for its phone business.

Group pre-tax profits are expected to come in at between £360m and £440m compared to more than £500m last year. “Currency fluctuations," says Dixons Carphone, "have meant that handsets have become more expensive whilst technical innovation has been more incremental. As a consequence, we have seen an increased number of people hold on to their phones for longer.”

There's also the impact of lower EU roaming charges. Dixons Carphone shares are down 33.6% year-to-date and 36% lower on the last 12 months.
