In the short term, the Federal Reserve's job is straightforward. Raise or lower interest rates in order to meet its employment and inflation targets. But over the years, it has evolved to do a lot more than just set the price of short-term bank borrowing. With each successive crisis, the Fed has taken on new powers and responsibilities to stabilize finance, markets and the broader economy. And with Washington characterized by partisan gridlock, the Fed is seen as the one entity that can actually move with some agility when it's needed. On this episode, we speak with Jeanna Smialek, a Fed reporter at the New York Times, and the author of the new book Limitless: The Federal Reserve Takes on a New Age of Crisis, about the history of the Fed and how it became so powerful.
