Dovish data and lower energy prices

UK CPI inflation was unexpectedly unchanged in May, at 2.8% y-o-y (consensus 3.0%).

While higher energy prices might have contributed to an uplift in air fares, price pressures

across much of the rest of the basket, including food and core goods, were comfortably

contained. In other news, of course, global energy prices have fallen sharply in the wake

of a US-Iran deal which should lead to the reopening of the Strait of Hormuz.

Lowering our forecasts, but upside risks linger

Mostly on account of lower energy prices, we significantly lower our near-term base case

for inflation. With oil prices currently at c.USD80/bbl pump prices will fall by around 2.5%

in June and by 5.5% in July, while lower gas prices could mean that utility bills will fall

gently from October. Taken together alongside the 0.1ppt downside news to our May CPI

forecast, we now forecast November peak inflation at 3.6% (4.1% previously). But we

maintain our end-27 CPI forecast at 2.3%.
