Asian shares drop as bond market pressures escalate

In the past few days, Asian shares have mostly declined, with Hong Kong's Hang Seng index dropping 2.1% and the Shanghai Composite index falling 0.7%. The bond market has been volatile, with rising yields raising concerns about higher borrowing costs affecting consumer spending. The Federal Reserve is struggling with inflation, which surged due to the Iran conflict disrupting oil shipments. Investors are closely watching the Fed's upcoming speech at the Jackson Hole symposium, as its decisions will significantly impact market stability.
