ChainCatcher news, according to Jinshi reports, Jane Foley, a foreign exchange strategist at Rabobank, stated that if Federal Reserve Chairman Powell remains cautious about interest rate cuts in the upcoming speech, speculators may close their previous dollar short positions in the short term. Both the market and Rabobank expect the Federal Reserve to cut rates in September, reflecting a weakening labor market. Foley pointed out that Powell may still maintain a cautious stance on policy easing when he speaks at the Jackson Hole central bank annual meeting this Friday, which could provide support for the dollar in the short term.
