This week's macro major events summary details the timing of Powell's speech this week, with several points of note:

1. Tonight at 2 AM, strictly speaking, this is the early morning of August 21, when the Federal Reserve will release the minutes of the July meeting, and several members will speak after the meeting.

2. This week, Powell's speech at Jackson Hole lasts for three days, from August 21 to August 23, U.S. time. The meeting is held according to Mountain Daylight Time (14-hour difference), so converted to Beijing time, it will be from August 22 to 24, which is from Friday to Sunday.

3. The meeting time is not certain, approximately in the evening U.S. time. Based on the time difference, August 21 evening + 14 hours is basically Beijing time on the morning of August 22. The earliest we can hear Powell speak will be on Friday morning.

4. The first day is the opening ceremony, where everyone goes through the motions and exchanges pleasantries. The focus is on the meeting the next day, where Powell will express opinions on the economy and the Federal Reserve's interest rate policy, so the key time is Saturday morning.

5. Based on this timeline, it looks like this weekend will be quite busy!
