The European session was characterized by caution and a 'wait-and-see' approach ahead of the critical US trading hours. European equities saw modest gains, with tech-related stocks showing some optimism, despite generally subdued German PPI data. Investors largely held their breath for Nvidia's after-market earnings report, which overshadowed most other macro catalysts. The anticipation built up throughout the session, leading to relatively low volume and tight trading ranges in many asset classes.

In the pre-US open, futures for the S&P 500 and Nasdaq showed muted activity, indicative of the prevailing uncertainty. While the Dow edged slightly lower, there was no significant directional conviction across indices. Commodities, however, provided some action, with Brent and WTI crude oil prices rallying sharply on renewed supply concerns and robust demand expectations, particularly ahead of the US summer driving season. Precious metals, conversely, saw some profit-taking, with gold and silver pulling back. The dollar traded within a narrow range against major currencies, influenced by conflicting signals from global economic data and ongoing central bank expectations. Asian markets earlier in the day responded to Chinese loan rates and Japanese BoJ commentary, setting a largely neutral tone.

The immediate risk for the US session is undoubtedly Nvidia's earnings report after the market close. Its guidance on AI spending and semiconductor demand will have a profound impact, not just on the tech sector but potentially on the broader market's risk sentiment. Ahead of that, fresh US economic data, including Initial Jobless Claims, Existing Home Sales, Philly Fed Manufacturing Index, and Flash PMIs, will provide updated insights into the health of the US economy. Any significant deviation from forecasts could influence Fed rate-cut expectations and dollar strength. Additionally, EIA Natural Gas Storage will be closely watched for energy markets, and speeches from ECB President Lagarde, BoE Governor Bailey, and FOMC Member Barkin could offer further monetary policy clues.
