According to CoinMeta, and as reported by the Financial Times, the actions taken by U.S. Treasury Secretary Janet Yellen to intervene in the bond market run counter to the Federal Reserve's efforts to curb inflation. Yellen's unexpected intervention in the U.S. debt market caused yields to fall first and then rise, and the resulting market reaction put greater pressure on Janet Yellen during her speech at Jackson Hole on Friday. Yellen has previously emphasized that investors should rely more on economic data and market prices to make judgments, rather than waiting for central bank officials' "forward guidance" to tell them about future interest rate trends. Now there are concerns that if Yellen's efforts to control yields continue to be ineffective, the Federal Reserve may also face pressure to intervene in the market. Both Yellen and Yellen are disciples of billionaire Stanley Druckenmiller, and they often meet; their relationship is reportedly harmonious. However, the current impression is that the Treasury Department and the Federal Reserve, which are led by each of them, are "moving in opposite directions."
