BoE’s Greene says war impact may unfold slowly, but inflation risks are paramount

BoE policymaker Megan Greene said the UK may need months to judge the lasting damage from the energy-price spike and that upside inflation risks from the Iran war are "paramount." She warned against waiting for definitive evidence of second-round effects, while the BoE remains on hold after unanimously keeping rates unchanged last month and investors price less than a 20% chance of a 25bp hike on April 30. The article points to higher inflation expectations and a more hawkish policy bias, even as growth risks remain.

Analysis

The market is still underpricing the persistence channel from the UK energy shock. The key second-order effect is not the initial CPI print, but the interaction between higher household inflation expectations and a BoE that is increasingly trapped by credibility: if the bank pauses too long, real rates fall and sterling weakens; if it hikes into a demand slowdown, it risks validating the recession narrative. That setup is supportive for front-end UK rates volatility even if outright growth data only deteriorate with a lag.

The clearest relative value is in the curve, not directionally in risk assets. A modest repricing of just one additional hike can lift 2Y gilt yields faster than 10Y, especially if the market starts to believe the BoE is prioritizing inflation optics over growth insurance. That argues for flatteners and for caution on domestic cyclicals with UK revenue exposure, while sectors with pricing power and shorter working-capital cycles should hold up better.

The consensus may be overestimating how quickly the energy impulse fades. If households are already more sensitive to price shocks, the pass-through into wage demands and services inflation can arrive before hard data confirms it, which means the window for a policy mistake is measured in weeks, not quarters. The main reversal catalyst would be a fast de-escalation in the geopolitical shock or a clean collapse in energy forward curves; absent that, the hawkish bias should keep the UK rates complex bid on selloffs rather than rallies.

A more contrarian angle is that the BoE’s hand may be forced less by inflation itself than by sterling stability. If FX weakens on the perception that the bank is behind the curve, imported inflation worsens and effectively tightens financial conditions automatically; that reduces the odds of an aggressive hiking cycle but increases the odds of a higher-for-longer hold with elevated volatility. In that regime, the best expression is not a big directional short in risk, but a relative short of UK duration versus peers and a selective long in energy/commodity-linked equities that benefit from the inflation impulse without domestic demand exposure.

Key Decisions for Investors

• Add a tactical long in 2Y SONIA/short 10Y gilts flattener for the next 2-6 weeks; risk/reward favors front-end repricing if the BoE sounds more hawkish than the market expects, while limiting outright duration risk.
• Buy GBP/USD downside via 1-3 month puts or risk reversals; if the market concludes the BoE is behind the curve, sterling can absorb the adjustment before rates fully reprice.
• Underweight UK domestic cyclicals and rate-sensitive retailers over 1-2 months; higher inflation expectations raise the odds of margin squeeze and demand fragility even without a deep recession.
• Long European integrated energy and North Sea-linked cash-generators on any pullback; they benefit from sustained energy price volatility and are less exposed to UK domestic slowdown risk.
• For event-driven hedging, buy short-dated FTSE 250 puts around the April 30 BoE meeting; implieds should remain efficient unless the market starts to price a genuine surprise hike.
