Asia Markets Flat Amid Sanctions Fears and Nvidia Earnings

Asia's stock markets were largely flat on Tuesday, while oil prices dipped in response to US warnings of 'economic D-Day' sanctions against Iran. The region's tech sector held its breath as Nvidia prepares to announce quarterly revenue that analysts expect to nearly double to $92 billion.

US Treasury yields retreated from recent highs after a report suggested the Treasury Department might tap into its cash account to finance increased debt buybacks, potentially reducing the need for additional short-term bill sales.

Fabien Yip, a market analyst at IG, noted that Nvidia's expected revenue is 'really high expectations to be met,' and investors are focused on whether the chipmaker can sustain its growth in upcoming quarters.
