Warren Buffett now owns more T-bills than the Federal Reserve.

It’s true: Buffett’s investment firm, Berkshire Hathaway, owns $235 billion worth of T-bills; the Fed owns $195 billion worth. Of course, most of the Fed’s money is in other government-guaranteed debt. Buffett’s is mostly in stocks. Still, his current cash holdings are about twice the average for the previous five years. How did he accumulate so much cash? By selling stocks in this heady environment.
