A recent JPMorgan survey indicates that investors are increasingly bullish on U.S. Treasuries, with net long positions reaching their highest level in nearly 15 years. Specifically, net long positions in U.S. government debt rose to levels not seen since October 2010, coinciding with a decline in the 10-year Treasury note yield from 4.80% to 4.53%. This surge in bullish sentiment comes ahead of the Federal Reserve's decision on interest rates, with some traders placing substantial bets on the outcome. One trader has wagered $2,500 on the Fed raising rates, potentially earning $1.66 million, while another has bet $1.86 million that there will be no rate changes, with a possible profit of $35,000. The overall investor sentiment reflects a complex economic backdrop, with mixed signals regarding job availability and consumer confidence in the stock market.
