Meyer表示，自美联储上次会议以来，大多数美联储决策者都对经济表达了更为普遍乐观也相对鹰派的看法。一些决策者暗示，他们认为最近的就业增长和通胀超标意味着朝着美联储就业最大化和稳定物价的目标取得“实质性进一步进展”，这种情况将允许他们开始缩减资产购买，甚至在明年底前就启动加息。\n至于退场的过程，杨水清表示可以用上一次货币政策调整的7个月时间作为参考。这要追溯到2013年，当年的5月，美联储会议纪要和时任主席伯南克首次公开讨论退出；9月，美联储开始列举QE退出理由和运用何种方法缩减QE规模；到了12月，美联储开始明确并实质性削减QE。","news_type":1,"symbols_score_info":{"161125":0.9,"513500":0.9,"QLD":0.9,"SPXU":0.9,"SDOW":0.9,"TQQQ":0.9,"ESmain":0.9,"QID":0.9,"SDS":0.9,"OEF":0.9,"SH":0.9,"UPRO":0.9,"DDM":0.9,"NQmain":0.9,"QQQ":0.9,"IVV":0.9,"DJX":0.9,"SPY":0.9,"MNQmain":0.9,"OEX":0.9,"DOG":0.9,"SSO":0.9,"PSQ":0.9,"SQQQ":0.9,"DXD":0.9,"UDOW":0.9}},"isVote":1,"tweetType":1,"viewCount":2790,"authorTweetTopStatus":1,"verified":2,"comments":[],"imageCount":0,"langContent":"EN","totalScore":0},{"id":152065783,"gmtCreate":1625242639642,"gmtModify":1703739348315,"author":{"id":"3581681754105950","authorId":"3581681754105950","name":"SingYourLife","avatar":"https://static.tigerbbs.com/fd0b735d5634aa1f5b3ba8c8099da765","crmLevel":11,"crmLevelSwitch":0,"followedFlag":false,"authorIdStr":"3581681754105950","idStr":"3581681754105950"},"themes":[],"htmlText":"Microsoft
