The Bank of England MPC will hold the Bank Rate at 4.5% at its March 19-20 meeting, with a vote split of at least 7-2 (hold-cut), meaning 2 or more members dissent in favor of a 25bp cut.

Evidence for (7)
- UK CPI estimated ~2.8% in March 2026, above the 2% target — prevents institutional authorization for a cut
- Hormuz closure has re-injected supply-side energy price pressure, creating hawkish cover for hold
- All four frameworks independently predict hold: Marxist (financial capital structural dominance), Austrian (incomplete malinvestment liquidation), Keynesian (cost-push institutional paralysis), Institutionalist (credibility preservation + May MPR as natural inflection point)
- 7-2 split has been the stable institutional equilibrium with Swati Dhingra as the most durable persistent dissenter — path dependence favors reproduction of existing vote pattern
- May 2026 MPR forecast revision is the structurally appropriate moment for any step-change; March lacks the forecast support to justify a deviation
- US tariff uncertainty and geopolitical instability elevate cut risk if BoE moves prematurely — hawks have multiple covering arguments
- Fiscal consolidation from October 2024 budget reduces the institutional case for complementary monetary easing
Evidence against (5)
- Effective demand deficiency may have advanced further than headline data shows, potentially broadening dovish dissent to 6-3
- Global cutting cycle (Fed, ECB) creates institutional pressure for BoE alignment, potentially shifting one hold vote to cut
- AI-driven services employment disruption and real wage squeeze could produce a demand data surprise before meeting, widening dissent
- Sterling resilience has reduced the credibility constraint argument for holding, removing one hawkish rationale
- Pakistan-Afghanistan escalation and broader geopolitical risk may depress UK growth forecasts more sharply than consensus anticipates
Reasoning chain
All four frameworks independently converge on hold at 4.5% — this cross-paradigm consensus is the strongest signal available when frameworks that disagree on mechanism agree on outcome. The compound prediction (hold AND 2+ dissenters) is well-supported: the hold component has approximately 0.88 probability given the inflation constraint and institutional path dependence; the 2+ dissenters component has approximately 0.87 probability given Dhingra’s structural position as permanent dove and the genuine demand conditions that justify at least one other dissent (supported by both Keynesian and Institutionalist analyses). The question’s ‘or wider’ framing further increases the probability since 6-3 also satisfies it. Key residual uncertainty is whether a data release before March 20 could shift the vote structure, and whether the Hormuz shock continues to generate hawkish signals or has been absorbed into expectations. Austrian credibility constraint and sterling vulnerability provide the most unique holding-force not captured by other frameworks; Institutionalist timing logic (May MPR as natural inflection point) reinforces why March is an unlikely moment for any structural shift.
Philosophical basis
Institutionalist framework provides the most direct mechanism: credibility-as-common-pool, path dependence, and quarterly MPR rhythm create structural friction against deviation. Austrian framework provides the most precise external constraint: sterling credibility via current account deficit and fiscal rent-seeking signal. Keynesian confirms the dissent pattern from the demand side, explaining why 2+ dissenters are durable without warranting a majority. Marxist provides structural backing for why the hold majority is durable rather than contingent on any single data point.
Falsification criteria
Falsified if (a) the MPC votes to cut the Bank Rate by any amount, OR (b) the MPC holds at 4.5% but with a vote split of 8-1 or 9-0 (fewer than 2 dissenters for cuts).

Brier breakdown
Post-mortem
Auto-resolved (falsified, confidence=0.95). Evidence: The Bank of England MPC held rates at 3.75% (not 4.5% as predicted) at its March 2026 meeting, with a unanimous 9-0 vote to hold — not the 7-2 split predicted. The rate had already been cut from 4.5% in a prior meeting. The unanimous hold was driven by Middle East conflict causing energy price surges that threatened to push inflation to ~3.5% in Q3 2026. Sources: https://www.bankofengland.co.uk/monetary-policy-summary-and-minutes/2026/march-2026; https://www.spf.co.uk/insights/market-insights/bank-of-england-holds-base-rate-in-march-2026/; https://moneyweek.com/news/live/economy/uk-interest-rates-march-bank-of-england. Reasoning: The prediction is falsified on two grounds: (1) The Bank Rate was 3.75% at the time of the meeting, not 4.5% — the prediction had an incorrect baseline rate. (2) The vote split was 9-0 (unanimous hold), which triggers falsification criterion (b): fewer than 2 dissenters in favor of cuts. The prediction required at least a 7-2 hold-cut split, but the actual split was 9-0 with zero dissenters for cuts.
