According to the latest data published by the UK Office for National Statistics (ONS) on Wednesday, the United Kingdom annualized Consumer Price Index (CPI) rose 8.7% in April against the 10.1% jump recorded in March. The market consensus was for an 8.2% increase.

Meanwhile, the Core CPI gauge (excluding volatile food and energy items) increased 6.8% YoY last month, compared with a 6.2% rise seen in March while beating expectations of a 6.2% clip.

The monthly figures showed that the UK Consumer Price Index climbed 1.2% in March vs. 0.8% estimates and 0.8% previous.

The UK Retail Price Index for April accelerated 1.5% MoM and 11.4% YoY, beating expectations across the time horizon.

An official from the UK Finance Minister Jeremy Hunt’s office said that “we must stick resolutely to plan to get inflation down.”

Meanwhile, Hunt noted, “although it is positive that it is now in single digits, food prices are still rising too fast.”

Why does UK inflation matter to traders?

The Bank of England (BOE) is tasked with keeping inflation, as measured by the headline Consumer Price Index (CPI) at around 2%, giving the monthly release its importance. An increase in inflation implies a quicker and sooner increase in interest rates or the reduction of bond buying by the BOE, which means squeezing the supply of pounds. Conversely, a drop in the pace of price rises indicates looser monetary policy. A higher-than-expected result tends to be GBP bullish.
