GBP: Disappointing Retail Sales Amidst Supportive Data

The UK released retail sales data for July this morning, and the numbers came in quite markedly below expectations. Retail sales including fuel dropped 1.2% month-on-month, and the ex-auto fuel gauge was down 1.4%.
The release is in contradiction with a slew of quite supportive data releases for the pound. However, the FX impact has been quite contained given the very little weight that retail sales are given in the Bank of England’s monetary policy decision equation compared to wage and inflation figures, which instead surprised on the upside this week.
The Sonia curve is fully pricing in a 6.0% peak rate in the UK, while markets are not convinced the ECB will hike rates at all. Incidentally, the euro is more exposed to China than the UK. That would suggest the 0.8500 support in EUR/GBP is under threat, and we definitely don’t exclude it will be tested or broken temporarily in the coming days. However, the short-term swap differential when the pair last traded at 0.8500 (mid-July) was around 20-25bp wider in favour of GBP, meaning that a further widening of the monetary policy divergence may well be needed to keep EUR/GBP sustainably depressed.
