Asian stocks and US futures fell on Monday as concerns about US debt ceiling negotiations weighed on market sentiments, hazardous banking fears and fresh geopolitical anticipations. US House of Representatives Speaker, Kevin McCarthy, and President, Joe Biden, meet on Monday to take a crucial call on the debt ceiling, less than two weeks before the end-of-May deadline. As the break in the negotiations last week, the inability to lift the debt ceiling might lead to a default and spark chaos in financial markets. Meanwhile, concerns over regional banks led US bank shares to continue their decline.
