UK money supply growth remains subdued, suggesting temporary inflation spike

M4 money supply ex-OFCs rose to 3.9% y/y in February (from 3.6% in January), consistent with CPI settling around 2-3% within ~18 months. Mortgage approvals increased to 62,584 (consensus 61,250) and consumer credit rose £1.9bn, but rising mortgage rates (2‑yr fixed could move from ~4.0% to ~4.8%) and financial tightening from the Iran war are expected to constrain credit and the housing market. That tightening may reduce the Bank of England's need to push policy much above the current 3.75%, versus ~4.50% that markets have priced in.

Analysis

The combination of structurally subdued M4 growth and a geopolitically driven tightening in financial conditions creates a narrow path for BoE policy: inflation risks are front-loaded via energy-led shocks, but monetary impulse is weak enough that the market’s near-term 75bp hike pricing (to ~4.50%) looks vulnerable to downward revision over a 3–12 month horizon. That mismatch is a levered macro trade: if CPI momentum fades as money growth stays muted, long-dated gilts and other rate-sensitive assets can rerate sharply as terminal-rate expectations pull back by 25–75bp.

Housing and consumer-credit dynamics create asymmetric credit risk 6–24 months out. Mortgage-rate increases compress origination volumes today but defer re-pricing pain into future vintages and unsecured credit: households using credit cards and personal loans to smooth will be first to show stress, which should widen unsecured spreads and pressure niche consumer finance equities and securitized paper before headline consumer insolvencies rise.

For growth/AI names, higher-for-longer real rates raise hurdle rates for long-duration software winners while benefiting providers of capital-intensive infrastructure that can translate into immediate cash flows (appliances, servers). That bifurcation favors tactical exposure to AI hardware demand (capture near-term capex cycles) and hedging of multiple/rate risk on software franchises — implement via options or pairs to keep convexity controlled. Cross-asset hedge: small long in gilts as a defensive hedge against a growth-shock outcome from credit strain or a prolonged energy spike.

Key Decisions for Investors

• SMCI: Tactical long call spread (buy Jul-2026 SMCI 1x notional call / sell Jul-2026 SMCI higher-strike call) to capture near-term AI infra capex. Timeframe 3–9 months. R/R: limited downside = premium; target 25–50% upside to spread value if enterprise AI projects accelerate. Size as 1–2% of equity risk budget and delta-hedge if IV rises above 40%.
• Pair trade — long SMCI / short APP (equal notional, 6–12 months): express preference for capital-intensive, revenue-recognized hardware over highly valued app monetization exposed to higher discount rates. R/R: if AI capex sustains, expect SMCI to outperform APP by 20–40% in 3–12 months; tail risk is a broad risk-off where both fall. Size: small net-market exposure (0.5–1% NAV directional).
• Macro hedge — long UK 10y gilt futures (GUKG or equivalent) for 3–12 months: position to capture a 25–75bp downward reprice in terminal BoE expectations driven by weaker broad money and slowing credit. R/R: ~4–6% potential price return if yields fall 50bp; downside if energy inflation resurges (losses of 6–8% if yields rise 50bp). Keep as a dynamic hedge (trim on oil > +15% move or risk-premium spikes).
