The dominant financial story this hour is the U.S. Treasury’s decision to double its government debt repurchases to at least $4 billion, a policy shift analysts are comparing to Operation Twist, which has catalyzed markets by driving long-term bond yields lower and pushing the U.S. dollar toward its lowest closing level since May. Against this backdrop of liquidity support, artificial intelligence remains a central driver of corporate activity; Google secured a $12 billion custom silicon deal with Marvell, while SK Hynix announced the largest share buyback in South Korean history—40 trillion won ($28.6 billion)—to stabilize its stock amid sector volatility. Nvidia is further cementing its infrastructure dominance by facilitating data center deals in the Nordics. Healthcare also marked a major milestone, with the Moderna and Merck combination cancer vaccine showing clinical superiority over Keytruda monotherapy in a late-stage trial. Geopolitical stresses continue to compound, evidenced by Israel's military launching rare criminal investigations into combat incidents involving Gaza civilian deaths, while domestic pressures intensify for the Ukrainian administration through new corruption probes and election calls. Meanwhile, Moscow has begun fuel rationing, attributing the supply shortage to unscheduled refinery maintenance following reported drone strikes.
