Markets brace for volatile week as US-Iran tensions, inflation data and Fed leadership changes converge
Five key themes are driving market sentiment this week, ranging from geopolitical friction in the Middle East to regulatory shifts at the Federal Reserve.

Global financial markets are navigating a week defined by five converging pressures that could significantly influence investor sentiment. Renewed diplomatic friction between the United States and Iran, the release of critical inflation data, a scheduled summit between President Donald Trump and President Xi Jinping, leadership changes at the Federal Reserve, and the initial public offering of AI chipmaker Cerebras Systems have created a complex landscape for traders.
Tensions in the Middle East have intensified following Tehran's rejection of a US-backed peace proposal. Iranian state television reported that the capital demanded a broader regional ceasefire and compensation for war-related damage, while reiterating its authority over the strategically vital Strait of Hormuz. In response, President Trump characterised the rejection as totally unacceptable on social media, heightening concerns over energy security and potential escalation in a region through which roughly one-fifth of global oil supplies pass.
Attention will also shift to the United States consumer price index figures scheduled for release on Tuesday. Economists forecast that headline annual inflation will rise to 3.7 per cent in April from 3.3 per cent in March, driven largely by higher energy costs linked to the ongoing conflict. While monthly price growth is expected to slow to 0.6 per cent, markets remain vigilant regarding whether rising crude oil prices are beginning to impact a wider range of consumer goods beyond fuel.
On the diplomatic front, President Trump is expected to visit China between 13 and 15 May for a summit with President Xi Jinping. This visit aims to ease tensions regarding trade tariffs, Taiwan, and the Iran conflict, potentially extending the trade truce agreed last October. The meeting marks a significant opportunity for the two largest economies to address regional flashpoints amidst a backdrop of ongoing geopolitical uncertainty.
Significant changes are also anticipated at the Federal Reserve as Chair Jerome Powell's term concludes on Friday. President Trump has nominated former Governor Kevin Warsh as his replacement, with Senate approval widely expected. A recent decision by the US Justice Department to drop a criminal probe into Powell regarding Fed headquarters renovations has cleared the path for Warsh's confirmation, removing a legal obstacle to the appointment.
Finally, the technology sector faces a major event with AI chipmaker Cerebras Systems preparing to list on the stock market under the ticker CBRS. Strengthened investor demand has reportedly led the company to consider raising its IPO price range to between $150 and $160 per share and increasing the share offering to 30 million. The debut comes amid rapid growth in AI adoption, which continues to drive demand for high-performance processors.
