Brexit Referendum Result Shocks Markets

Leave prevailed against expectations, driving GBP/USD briefly below 1.33 as markets recalibrated trade, investment, and regulatory paths. European bank equities fell hard and safe havens rallied. The BOE signaled readiness to provide liquidity; gilt yields dropped as duration demand spiked. Risk models suffered from parameter breaks as correlations converged. The vote initiated a multi-year process with Article 50 to follow, not an immediate macro endpoint.

We judged the shock to be large on uncertainty but gradual in economic realization. The UK’s current account and reliance on portfolio inflows increased sensitivity to confidence. The euro area faced political spillovers but had backstops in place. We expected a lower UK neutral rate and weaker investment trajectory. Currency became the prime adjustment valve, with inflation set to rise on imports even as growth cooled.

In client portfolios we lifted cash and core fixed income, using gilts and Treasuries as hedges. We raised FX hedges on euro and sterling exposures and cut UK small-cap risk more reliant on domestic demand. We avoided de-risking quality global exporters listed in London that benefit from a weaker pound. Where liquidity was at a premium, we used futures overlays to manage beta while steering clear of impaired bid-ask in single names.

We set milestones for adding risk back: clarity on Article 50 timing, BOE easing, and corporate guidance on supply chains. We emphasized dividend resilience and balance-sheet strength in UK equities and stayed neutral on UK credit pending policy direction. The aim was to absorb volatility without surrendering long-term positioning in franchises with durable global revenue.
