The UK S&P Global Composite PMI printed at 49.7 in May, beating the consensus forecast of 48.5. That reading remained below the 50 threshold that separates expansion from contraction, pointing to continued, albeit mild, shrinkage in private-sector activity.
The outturn suggests momentum was firmer than markets had pencilled in for the month, even as overall conditions stayed slightly negative. The data add to a mixed near-term picture for UK growth, with the composite measure indicating a marginal underperformance relative to a flat reading.
Market Impact and Trading Implications
The UK’s economic activity for May showed a contraction, but it was less severe than the markets were braced for. We see this “better-than-expected” bad news creating a short-term floor for UK assets like the FTSE 250 index. Traders should consider selling out-of-the-money puts with short expirations to collect premium from the expected stability.
This data should give the British Pound a slight boost, especially against currencies where the economic outlook is weaker. With UK inflation still proving stubborn at 3.1% last month, the Bank of England is unlikely to cut rates before the US Federal Reserve. We are therefore looking at buying short-dated call options on the GBP/USD pair, targeting a move back above the 1.28 level seen earlier this year.
Monetary Policy and Volatility Outlook
We cannot ignore that this is the third straight month of economic contraction, which reinforces the larger trend of a weakening economy. This confirms our view that the Bank of England’s next move will be a rate cut, likely in the fourth quarter. We will be looking to add to positions in SONIA futures that would profit from lower interest rates toward the end of 2026.
The conflicting signals of a contracting economy beating forecasts will increase market indecision and volatility. Implied volatility on FTSE 100 options, which recently hit a yearly low of 12%, has already ticked up to 14% and we expect it to climb further. This is a clear signal to consider buying straddles on the index to play a significant price move in either direction over the coming weeks.
