BlackRock Investment Institute has upgraded its allocation rating on U.S. Treasuries, ending a nearly six-year underweight stance as rising yields have made potential returns more attractive. Strategists cited higher yields and the market's possible overpricing of Federal Reserve tightening expectations as key factors driving the adjustment in their latest report. The asset manager simultaneously downgraded U.S. equities to neutral while increasing Treasury allocations across various maturities. Despite the broader upgrade, BlackRock maintains a preference for short-term bonds within its fixed-income strategy.
