Bank of England raises rates to 4% as it forecasts inflation near 5% next year

The Bank of England raised its benchmark interest rate by 25 basis points to 4% on Nov. 5 as a prolonged energy shock increased its inflation concerns. The move highlights a potential source of pressure on Bitcoin investors exposed to sterling borrowing.

Eight policymakers backed the increase, while Catherine Mann preferred a larger, 50-basis-point move to 4.25%. The Bank projected UK consumer-price inflation around 5% in the second quarter of 2027, following September's 3.5% reading. The median in the Bank's Market Participants Survey already expected a 4% rate in November, which limits the case for treating the announcement as a fresh market shock.

The decision came despite limited evidence so far that the energy shock was spreading into broader wage and price-setting. Policymakers judged the pressure building in the economy sufficient to act, with stronger-than-expected activity adding to the case. That leaves persistence, including firms passing on costs and workers seeking higher pay, central to the next policy decisions.

UK borrowing costs were already rising. Forward market interest rates were feeding into rates faced by some households and firms, and benchmark two-year mortgage rates had risen nearly 50 basis points since the beginning of September. Business lending growth remained strong, showing that financing pressures were uneven.

For investors exposed to sterling borrowing, higher financing costs could leave less room for Bitcoin positions. A broader reduction in willingness to take risk could also curb allocations.

Historical research supports the risk-taking mechanism. An IMF working paper published in August 2023 found that US Federal Reserve tightening reduced an aggregate crypto price factor through that channel. The factor's increasing correlation with equities coincided with institutional investors entering crypto. The finding concerns historical US policy and aggregate crypto prices, which limits its application to this UK decision.

The distinction matters for dollar funding. The Bank of England sets UK Bank Rate. Establishing a change in current US dollar financing conditions would require separate evidence, as would attributing a Bitcoin price move to this announcement.

The inflation outlook is conditional. 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 relied partly on downward-sloping futures prices and base effects, as earlier price increases drop out of annual comparisons.
