Financial markets are facing another eventful week, with oil prices rising amid geopolitical tensions, AI-related stocks experiencing renewed volatility, and investors closely monitoring economic data and corporate earnings.
Here's a closer look at what's moving markets and what could come next.
Oil prices: What's driving the latest rally?
Oil prices are back in focus as escalating tensions in the Middle East raise concerns about potential supply disruptions. Brent crude has climbed above $110 per barrel, with investors closely monitoring developments around the Strait of Hormuz and the wider Gulf region.
Attention is also turning to today's US Energy Information Administration (EIA) oil inventory report. Markets are expecting a decline of approximately 1.2 million barrels in US crude inventories, following an 8.6 million barrel drawdown the previous week.
A larger-than-expected decline could provide further support for oil prices, while an unexpected increase in inventories may ease some of the upward pressure.

AI stocks: Is market volatility here to stay?
After months of enthusiasm surrounding artificial intelligence, investors are increasingly questioning whether the significant investment in AI infrastructure will translate into sustainable profits.
Technology and semiconductor stocks have experienced sharp fluctuations, with companies such as CoreWeave coming under pressure amid concerns about AI spending, financing costs and valuations.
However, the wider market picture remains mixed. While the Nasdaq has struggled to gain momentum, other areas of the US stock market have shown resilience, suggesting investors are becoming more selective rather than abandoning equities altogether.
With earnings season underway, upcoming corporate results could play an important role in determining whether confidence in the AI sector recovers or volatility continues.
What else should investors watch today?
UK inflation has accelerated to 3.5% annually, above market expectations of 3.4%, adding to uncertainty around the Bank of England's next interest rate decisions.
Meanwhile, today's US 20-year Treasury auction will offer another indication of investor demand for government debt, with bond yields remaining an important factor for equity valuations.
With inflation, monetary policy, oil prices and corporate earnings all influencing sentiment, investors have plenty to monitor in the sessions ahead.
