Investors are increasingly turning to U.S. Treasury ETFs as market volatility disrupts traditional safe-haven assets. In March, net inflows into these ETFs surged to approximately $30 billion, more than doubling the recent monthly average. Demand is particularly strong for ultra-short products like SGOV and BIL, according to Eric Balchunas, Senior ETF Analyst at Bloomberg. This shift comes as U.S. equities decline and gold's performance disappoints, breaking their expected "zero correlation." With limited safe-haven options, some analysts suggest holding cash as a prudent strategy. Notably, Berkshire Hathaway recently purchased $17 billion in U.S. Treasury bonds, reflecting confidence in these assets.
