Asian stocks broadly advanced on Friday, led by South Korea’s technology shares, while most major regional benchmarks remained on track for weekly declines. U.S. equities had opened higher after the Treasury Department announced that longer-term bond buybacks would at least double from $2 billion to a minimum of $4 billion per operation starting September 9, briefly pushing the 10-year yield from 4.71% to 4.64%. The relief proved temporary: the 10-year yield later returned toward 4.7%, while the 30-year yield rebounded to 5.27%. The program, scheduled from September 9 through November 4, was intended to improve liquidity but did not resolve concerns over more than $40 trillion of government debt, a deficit above 6% of GDP, annual interest costs near $1.2 trillion, elevated issuance, inflation, oil prices and geopolitical risks linked particularly to Iran. About $8.5 trillion of fixed-rate U.S. government debt issued during the low-rate era will mature between 2026 and 2028 and be refinanced at rates 2 percentage points higher, potentially increasing the annual interest burden by about $170 billion. The bond-market reversal contributed to dollar softness and gains in Asian currencies, Bitcoin and gold, while investors monitored Federal Reserve policy, fiscal developments, geopolitical events and inflation data.
