Technology and artificial intelligence continued to drive markets in May, helping equity markets push higher despite ongoing geopolitical uncertainty. At the same time, bond markets remained more cautious as investors weighed the potential impact of higher inflation and interest rates.
Here are five developments advisers should have on their radar.
1. The war in Iran is starting to hit UK pockets
The conflict in Iran is beginning to have a more visible impact on UK households. Fuel prices rose above 158p per litre in May, their highest level since the conflict began, and the energy price cap is set to increase from July. For the average household, that means around £221 a year in additional energy costs.
Higher energy prices are a reminder that geopolitical events will feed through to household finances.
2. AI continues to shape global stock markets
Last month saw Samsung, SK Hynix, and Micron, three memory chip companies, all achieve market values of over $1tn. The Korean and Taiwanese stock markets have seen large gains throughout May, fuelled by chip companies seen to gain from the AI boom.
In the US, markets have also continued to rise despite the concerns around the Iran war, with the S&P 500 remaining above pre-conflict levels.
3. Big AI IPOs are on the horizon
SpaceX filed for its stock market listing in May. Combining AI technology with space innovation, the listing is expected to be one of the biggest ever and could make Elon Musk the first trillionaire. OpenAI and Anthropic are also potential future listings, with valuations that could make them significant additions to public markets.
Large new listings don't just create investment opportunities. They can also affect index composition, increase concentration, and influence how capital flows through markets. These are important considerations when thinking about diversification.
4. UK Gilt yields rise
Over the past month, we’ve seen gilt yields increase due to fears of increased inflation and uncertainty over Keir Starmer’s leadership. The 10-year gilt yield rose to 5.17%, the highest since before the 2008 global financial crisis, before slightly easing towards the end of the month. Although rates were unchanged in May, there could be a rise on the horizon.
5. A new Federal Reserve Chair takes centre stage
Kevin Warsh was sworn in as Chair of the Federal Reserve during May. Handpicked by Trump, he takes charge of the central bank at a time of mounting pressure over Americans’ financial wellbeing. A highly divisive political appointment, as the vote to approve him was split along party lines, everyone is watching closely to see what he’ll do with interest rates. Trump wants him to cut them which goes against conventional wisdom to raise them when facing rising inflation.
