UK Inflation: September CPI and Implications for the Bank of England

What happened

The UK is awaiting the release of its September Consumer Price Index (CPI) report, a key event on the economic calendar. Market expectations point to an increase in annual inflation, with headline CPI projected at +3.4% (up from +3.1% previously) and core CPI at +2.8% (up from +2.6%). These projections indicate continued inflationary pressures, which are already significantly above the Bank of England's (BOE) 2% target.

Energy costs are expected to remain a relevant factor for inflation. However, the primary focus is on the details of underlying inflation, particularly the stickiness of services prices. Any signs of broader price pressures taking hold would make the BOE's monetary policy balancing act even more difficult.

Why it matters

The September CPI report is of paramount importance for the Bank of England's outlook. While markets are already pricing in approximately 96% odds of a 25 basis point rate hike on November 5, a stronger-than-expected inflation print might not alter this immediate decision but would reinforce the need for further monetary tightening beyond November. Currently, the odds of a back-to-back hike in December are estimated at around 61%.

Conversely, a softer-than-expected inflation report would be a more surprising outcome. While it might not be enough to derail a November hike entirely, it could lead investors to pare back some of their more aggressive BOE rate expectations. In addition to the CPI, the autumn budget, scheduled for October 28, will also be an important consideration for the BOE before its next meeting.

Market impact

• Interest rates and bonds: A higher-than-expected CPI would tend to push up UK government bond (gilt) yields, reflecting expectations of higher interest rates for longer. A weaker CPI could alleviate this pressure, leading to a fall in gilt yields.
• Dollar and exchange rates: The British pound (GBP) tends to strengthen against the dollar and other currencies if the CPI comes in above expectations, as this would reinforce BOE tightening expectations. A weaker CPI could weaken the pound.
• Equities: A higher and persistent CPI could be negative for UK equities, such as the FTSE 100, as higher interest rates increase borrowing costs for companies and can slow economic growth. A weaker CPI could be marginally positive, easing pressure on interest rates.
• Brazil: Indirectly, a scenario of persistent inflation in the UK and BOE monetary tightening may contribute to a global environment of increased risk aversion and a stronger dollar, which tends to pressure the real and Brazilian assets in general.

What to watch

Investors should closely monitor the release of the September CPI report, with particular attention to core inflation components and services prices. Market reactions in the British pound and gilt yields will be important indicators. Furthermore, the autumn budget, to be announced on October 28, will be an additional factor for the BOE and markets to consider.

Scenarios

Base Case: Inflation in line with or slightly above expectations, confirming the 25 basis point hike in November and keeping the door open for further hikes in December. Gilt yields remain elevated, and the pound is stable or slightly stronger. Risk Scenario: Inflation significantly weaker than expected, leading to a reassessment of BOE tightening expectations, although a November hike would still be likely. This could result in a fall in gilt yields and a weakening of the pound.
