Asia-focused banks face mounting pressure from volatile bond markets, persistent inflation, and foreign exchange fluctuations, raising concerns about profitability and capital strength as lenders prepare to report third-quarter earnings, Reuters reported.While major regional banks continue to benefit from healthy deposit bases and solid earnings, rising long-term bond yields and broader macroeconomic headwinds are exposing vulnerabilities across their balance sheets, analysts said, Reuters reported.The concerns follow a global bond market sell-off in early October, when the benchmark 10-year US Treasury yield touched a multi-year high of 5.34% before stabilising around 5.11%.
