Asian markets opened with caution as investors awaited key economic indicators. MSCI's broad index of Asia-Pacific shares outside Japan slipped 0.3% and was down 1.9% for the week.

The focus is on Friday's nonfarm payrolls report, which comes ahead of the US presidential election on Tuesday and the Federal Reserve's policy meeting the following day. Treasury yields are near three-month highs, reflecting market sentiment as a rate cut next week appears largely anticipated.

Meanwhile, oil prices continued to rise, with Brent crude increasing nearly 2% to $74.13 a barrel amid reports of potential military actions involving Iran and Israel. In the US, Nasdaq futures gained 0.3% following a significant 5.3% increase in Amazon's stock after the company reported third-quarter profits exceeding Wall Street expectations, bolstered by strong retail sales. This surge added $104 billion to Amazon's market capitalization, highlighting the tech sector's resilience amid broader market caution.
