Bora Yalın – Lead Researcher, International Capital Flows: The macro‑economic fallout from the UK heatwaves extends beyond immediate output shortfalls, signalling a structural shift toward climate‑resilient policy frameworks. Heightened liquidity pressures and volatile energy pricing are likely to trigger a risk‑off pivot, prompting hedge funds to rebalance European exposures. Proactive urban cooling measures will not only safeguard domestic productivity but also anchor global capital flows against climate‑induced shocks.
