Evidence for (8)
- UK inflation has decelerated significantly toward the 2% target (currently 2.5-3% on most measures), reducing the rationale for holding at 4.5%
- GDP growth remains weak at 0.1% in Q4 2025, suggesting the economy does not require restrictive policy
- Labor market is softening with unemployment rising and wage growth moderating, reducing inflation pressures
- Real interest rates of approximately 2.5% (4.5% nominal minus 2% inflation) are restrictive by historical standards and damaging to investment
- Household debt servicing costs have surged following rate increases, dampening consumer spending and economic growth
- Recent communications from dovish MPC members have signaled concerns about prolonged restrictive policy damaging growth
- BoE's own guidance emphasizes gradual rate reductions as inflation moderates, suggesting emerging dovish sentiment on the committee
- Global central banks are shifting toward rate cuts as inflation recedes, creating peer pressure on the BoE to normalize policy
Evidence against (7)
- The original prediction carries high confidence (76%), reflecting strong professional consensus on a 7-2 hold vote
- BoE communications through early March emphasized a 'wait and see' approach, not imminent policy changes
- Inflation remains above the 2% target on several measures, providing hawkish justification for holding
- Financial markets price only 15-20% probability of a March cut, suggesting overwhelming expectation of a hold
- The BoE has historically been cautious, preferring to hold longer than expected when inflation persists above target
- Recent BoE forward guidance has emphasized that cuts will come 'gradually,' implying no surprise immediate moves
- A 7-2 vote split suggests strong consensus within the MPC, consistent with the BoE's recent hawkish positioning
Reasoning chain
The original prediction assumes strong MPC consensus (7-2) for holding at 4.5%. However, as inflation has moderated toward target and growth has weakened substantially, emerging dovish sentiment on the committee may be underestimated. While an outright rate cut remains unlikely in March, a more fractured vote with 3+ members dissenting for a cut is plausible and would signal growing dovish pressure that the original prediction’s 7-2 split does not capture. Historically, BoE dissent votes of 3+ members dissenting on policy direction occur in 20-25% of meetings. Current conditions—inflation moderating, growth weak, real rates restrictive by historical norms—mirror periods preceding past policy inflection points, suggesting higher-than-baseline dissent probability.
Falsification criteria
The counter-prediction is FALSE if both of the following are true: (1) the Bank Rate is held at exactly 4.5%, AND (2) no more than 2 MPC members vote in favor of a 25bp cut. The counter-prediction is TRUE if either the Bank Rate is cut to 4.25% OR 3 or more members vote for a cut.
Brier breakdown
Post-mortem
Auto-resolved (falsified, confidence=0.97). Evidence: The Bank of England MPC, at its meeting ending 18 March 2026, voted unanimously 9-0 to maintain Bank Rate at 3.75%. Zero members voted for a cut. Notably, the rate going into the meeting was already 3.75% (not 4.5% as the prediction's premise assumed), and the unanimous hold was driven by Middle East conflict causing an energy price shock that prompted even members who had been inclined to cut to vote for a hold.

Reasoning: The prediction required either (1) a cut to 4.25% or (2) 3+ MPC members voting for a 25bp cut. Both conditions failed: the rate was not cut (held at 3.75%), and the vote was 9-0 to hold with zero dissents in favor of a cut. The prediction's embedded premise that the rate was at 4.5% was also incorrect — it had already been cut below that level before this meeting. Neither trigger condition in the prediction was satisfied.
