Bond Markets Under Pressure
The yield on the 30-year US Treasury bond rose to its highest since 2007 earlier this week, before pulling back after the Treasury Department announced it would at least double debt purchases. On Thursday, yields resumed their climb, with the 30-year up 5 basis points to 5.244% and the 10-year also rising 5 basis points to 4.69%. This comes as total US debt topped $40 trillion for the first time, raising concerns about fiscal sustainability.
The Federal Reserve's latest meeting minutes revealed that policymakers are worried about persistent inflation, with several officials ready to hike interest rates further. This hawkish stance has kept bond markets on edge, as investors recalibrate expectations for monetary policy.

In contrast, biotech company Moderna dropped nearly 21% after a dramatic 177% surge the previous day, following positive results for its mRNA skin cancer therapy in a late-stage trial. The volatility underscores the speculative nature of biotech stocks.
In the UK, the FTSE 100 slipped 17 points, or 0.16%, to 10,726, reflecting broader global weakness. Meanwhile, the dollar fell to three-month lows against a basket of major currencies, with the pound hitting a six-month high against the greenback.
