Global markets are navigating a complex landscape marked by geopolitical instability, central bank decisions, and significant corporate earnings reports. Indian equity markets, as indicated by GIFT Nifty, are set for a positive start, trading 130 points, or 0.54%, higher at 24,221.5. This optimistic opening comes even amidst heightened US-Iran tensions in the Middle East, with investors assessing the impact of military strikes and surging crude oil prices. WTI crude has climbed to around $82 per barrel, and Brent crude is near $86.8 per barrel, driven by a fresh geopolitical risk premium. However, some reports on July 28 indicated that oil prices, like Brent crude, had fallen to $88.36 per barrel following a pause in US-Iran strikes, suggesting a volatile situation.

The US Federal Reserve's monetary policy announcement is expected later today, with markets largely anticipating unchanged interest rates. However, traders are pricing in the possibility of a surprise rate hike due to rising oil prices and persistent inflation concerns. The Fed's commentary will be crucial for influencing global equity markets. Earlier in the week, some reports suggested that calming Middle East hostilities had eased concerns about further rate hikes, contributing to Monday's gains in European markets like Frankfurt (up 1%), London, and Paris.

Investor sentiment remains cautious due to fresh attacks involving US and Saudi forces against Iran-aligned militant groups in Iraq on July 28. Separately, Iran's IRGC claimed to have struck 85 important US military installations. These events, combined with the earlier rocket attack on Kharg Island and strikes on US military bases, have revived concerns over global energy supplies. Amidst this, major tech earnings from Microsoft, Meta, Apple, Amazon, SK Hynix, and Samsung are highly anticipated, with focus on their outlooks and spending plans, especially concerning the global AI trade. While Asian stock markets like Tokyo, Seoul, Hong Kong, and Shanghai advanced, early gains on Wall Street did not hold, with only the Dow finishing positive and tech stocks dragging down the Nasdaq Composite, partly due to a hefty drop in AI processor heavyweight Nvidia.
