According to CoinMeta, a research report by CITIC Securities states that Federal Reserve Chairman Jerome Powell will deliver a keynote speech at the Jackson Hole Symposium this Friday. Against the backdrop of high long-term U.S. Treasury bond yields and the brief effectiveness of repurchase announcements, his speech has become one of the few potential trading benchmarks for the market recently. This is an opportunity to assess Powell's communication skills, and it may be necessary to adjust the previously “vague” communication strategy. It is particularly important to pay attention to the content regarding policy transparency, which is more significant than whether his stance is considered “hawkish” or “dovish” in the traditional sense.
