Emerging market stocks took a hit on Thursday as Brent crude held above $100 a barrel, fueled by renewed shipping attacks in the Middle East. The rise in energy costs, combined with anticipation of Friday's US inflation report, kept investors on edge across developing economies.

Oil's climb and shipping fears

Brent crude, the international benchmark for oil prices, has stayed above the $100 mark after a series of shipping attacks in the region, particularly around the Strait of Hormuz. These attacks have raised concerns about supply disruptions, pushing energy prices higher. For emerging markets, many of which are net importers of oil, higher energy costs can translate into wider trade deficits and increased inflationary pressure.

The latest developments echo earlier tensions that have kept the oil market volatile. As Brent crude holds above $100, the ripple effects are being felt across global markets, with bond markets also on edge. Higher oil prices can feed into inflation expectations, prompting central banks to keep interest rates higher for longer, which tends to weigh on riskier assets like emerging market equities.

US CPI report in focus

Investors are now looking ahead to Friday's release of the US Consumer Price Index (CPI), a key measure of inflation. The report will give clues about the Federal Reserve's next policy moves. If inflation comes in hotter than expected, the Fed may be forced to keep rates elevated, which could strengthen the US dollar and put additional pressure on emerging market currencies and stocks.

In recent weeks, Hong Kong stocks slipped as oil stayed above $100 and US inflation loomed, and similar patterns have been seen across the region. The combination of high energy costs and uncertainty about US monetary policy has made investors cautious about putting money into emerging markets.

What this means for investors

For everyday investors, the slide in emerging market stocks highlights the interconnected nature of global markets. When oil prices spike, it can affect not only energy companies but also the broader economy, especially in countries that rely heavily on oil imports. Higher energy costs can squeeze corporate profits and reduce consumer spending power, which may show up in weaker stock performance.

Friday's US inflation report is a critical data point. A higher-than-expected reading could lead to expectations of more aggressive Fed rate hikes, which often strengthens the US dollar. A stronger dollar makes emerging market debt more expensive to service and can lead to capital outflows from developing economies.

Investors should also keep an eye on how shipping disruptions evolve. The Hormuz attacks have revived shipping fears, and any escalation could push oil prices even higher, adding to the headwinds facing emerging markets.

Broader market context

The current environment is reminiscent of other periods when oil prices surged, such as during geopolitical conflicts in the past. In those times, emerging markets often underperformed as investors sought safer havens. However, not all emerging markets are equally affected. Countries that are net exporters of oil, like some in the Middle East and Latin America, may benefit from higher prices, while importers like India and Turkey tend to suffer.

In Asia, China and Hong Kong stocks slid as oil held above $100 on Mideast tensions, reflecting the regional impact. Meanwhile, foreign investors have returned to Asian stocks on AI optimism, but the current oil shock could test that resilience.

Looking ahead

The key question for investors is whether oil prices will stay above $100 and how the US inflation data will shape Fed policy. If inflation remains sticky, the Fed may keep rates higher, which could prolong the pressure on emerging markets. On the other hand, if inflation shows signs of cooling, it could ease concerns and provide some relief to these markets.

For now, the combination of high energy costs and upcoming inflation data is keeping emerging market stocks on the back foot. Investors should monitor these developments closely, as they could have significant implications for global portfolios.
