The event that moved markets this week was not on anyone’s list. On Wednesday morning in New York, the U.S. Treasury said it would at least double how many long-term government bonds it buys back from the market. That is a plumbing move to keep the bond market working smoothly, not a change in interest rates. But it pushed bond yields down, and when yields fall the dollar usually loses some of its appeal. The dollar dropped to a three-month low, and gold, Bitcoin and stocks all jumped. The one scheduled event this week, the Fed minutes on Wednesday evening, actually leaned hawkish, meaning the Fed sounded more worried about inflation than expected. Normally that would lift the dollar. It landed hours after the buyback news, and the market barely reacted. So the surprise, not the scheduled event, ran the week.
