Weekly Market Update 20/05/2026

In this weekly market update, we look at the forces currently pulling investors in different directions. Strong earnings upgrades have helped push some equity markets back towards all-time highs, with the US and technology sectors leading the way. However, market breadth remains narrow, and retail investor momentum may leave equities more vulnerable to a short-term shake-out.

The update also explores why the global economy has remained resilient despite the supply-side shock from the Middle East, including delayed effects from oil prices, lower oil intensity, well-anchored inflation expectations, and the continued impact of the AI investment boom.

Geopolitical tensions remain a major focus, with US-Iran headlines becoming more hawkish and renewed concerns around Middle East energy facilities keeping oil prices volatile. Key data to watch this week includes global flash PMI readings, UK inflation, consumer confidence, retail sales, and public finances.
