BoE lifts rates to 4% as 5% inflation looms

The Bank of England raised its benchmark interest rate by 25 basis points to 4% on Nov. 5, citing a prolonged energy shock that increased inflation concerns. The decision was supported by eight policymakers, while Governor Catherine Mann advocated for a larger 50-basis-point increase to 4.25%. The central bank’s move follows a September consumer-price inflation reading of 3.5% and projects UK inflation to reach approximately 5% in the second quarter of 2027.

Policy Decision and Market Expectations

The rate increase was implemented despite limited evidence that the energy shock was spreading into broader wage and price-setting mechanisms. Policymakers determined that pressure building in the economy was sufficient to warrant action, noting that stronger-than-expected economic activity added to the case for tightening. The median expectation in the Bank’s Market Participants Survey had already indicated a 4% rate for November, suggesting the announcement did not constitute a fresh market shock. The central bank emphasized that persistence in inflation, including firms passing on costs and workers seeking higher pay, remains central to future policy decisions.

Sterling Borrowing Costs and Crypto Allocations

UK borrowing costs had already risen prior to the decision. Benchmark two-year mortgage rates increased by nearly 50 basis points since the beginning of September, while business lending growth remained strong, indicating uneven financing pressures across the economy. For investors exposed to sterling borrowing, higher financing costs could reduce the capacity to hold Bitcoin positions. Additionally, a broader reduction in risk-taking appetite could curb allocations to digital assets.

An IMF working paper published in August 2023 provides historical context for this risk-taking mechanism. The study found that US Federal Reserve tightening reduced an aggregate crypto price factor through this channel. The research noted that the crypto price factor’s increasing correlation with equities coincided with the entry of institutional investors into the market. However, this finding concerns historical US policy and aggregate crypto prices, which limits its direct application to the current UK decision. The Bank of England sets the UK Bank Rate, not US dollar financing conditions. Establishing a change in current US dollar financing conditions would require separate evidence, as would attributing a specific Bitcoin price move to this announcement.

Inflation Outlook and Energy Prices

The Bank’s inflation outlook is conditional on specific energy price assumptions. The near-term projection used energy prices averaged over the 15 UK working days ending Oct. 27. The projected later decline in direct energy contributions relies partly on downward-sloping futures prices and base effects, as earlier price increases drop out of annual comparisons. Lower energy prices accompanied by easing rate expectations would weaken the proposed bearish allocation channel for Bitcoin. Similarly, resilient Bitcoin demand that withstands tighter financing conditions would also mitigate this pressure. The Bank kept future policy dependent on incoming evidence, identifying wages, firms’ pricing behavior, and demand as important tests of how far the energy shock travels.
