The combination of lacklustre UK economic data and political noise is highlighting the pound's short-term vulnerabilities. But major GBP fallout looks unlikely.
It looks like top central bank officials - including ECB President Mario Draghi and Fed Chair Janet Yellen - will remain tight-lipped over future policy plans at Jackson Hole this week, with a big picture focus on central banking and the global economy removing any significant event risk for markets. While Draghi will undoubtedly sound more upbeat on the prospects for the Eurozone economy relative to his 2014 Jackson Hole speech, we do think the ECB chief will be more careful with his choice of words when speaking in Lindau (Wednesday) and Jackson Hole (Friday) this week. Indeed, the July minutes expressed concerns over a possible front-running of ECB policy normalisation within markets, which to some extent highlights the current market-sensitive nature of central bank talk.
The UK government outlined its position on future customs arrangements with the EU last week and while a transitional period is sought, the lack of clarity on its length may be seen as a near-term disappointment. We expect GBP to trade with a negative bias ahead of the governing Conservative party conference and key Brexit talks in October. However, we see this as a short-run phenomenon at best; it's difficult to see any material GBP fallout in the absence of any flaring tail risks such as a breakdown in the UK-EU negotiations and renewed cliff-edge Brexit risks. We'll be closely watching how business sentiment is holding up in the August CBI surveys (Tuesday & Thursday).
