The Wall Street Journal wrote, "The Return of the Repo: A Market's Postcrisis Comeback." They tell us, "An obscure but vital corner of financial markets that was at the center of the financial crisis is making a comeback. Investors and banks use repurchase agreements, or repos, to borrow large amounts of short-term cash safely, by selling a security and pledging to buy it back at a slightly higher price in the near future. On the other side of that trade, it provides cash-rich asset managers with a safe place to put money. This market played a central role in the crisis, when it froze as investors questioned the safety of the securities being lent. Post-2008 regulations made it more expensive for banks to get involved, further denting a market that relies on these institutions to act as middlemen. Now banks are beginning to return to that role while investors need safe places to store their cash." See also the New York Fed's Liberty Street Economics blog, which wrote, "How Much Is Priced In? Market Expectations for FOMC Rate Hikes from Different Angles." It says, "In contrast to previous posts, our main focus is on analyzing market participants' perceived probability of an increase in the federal funds target range leading up to individual upcoming FOMC meetings rather than expectations for the entire expected path for future policy rates. We focus on the current monetary policy normalization cycle that started with "liftoff" in December 2015 and has included three further rate hikes so far (in December 2016, March 2017, and June 2017)."
