The Federal Reserve raised its target for the federal funds rate by 25 basis points on Wednesday, its first rate hike in more than three years. Fed Chairman Kevin Warsh cited inflation* that has been “too high for too long” as the principal reason for the move. Warsh has maintained a commitment to getting the inflation rate back to the Fed’s stated goal of 2 percent annually since being confirmed.
Opinions vary on the decision. President Trump, always and everywhere a proponent of lower interest rates, managed to criticize the move without castigating Warsh, whom he just appointed chairman. Instead, Trump blamed “the board,” meaning the Fed’s Board of Governors, saying, “The board is very hostile. They’re very political. They’re doing the wrong thing.”
Meanwhile, longtime Fed critic Peter Schiff argued on his podcast that the rate hike is far too small given the current inflation rate, arguing that the Fed should have started with at least a 50 percent hike and continued higher from there.
To the extent the federal funds rate affects price levels, Schiff is correct. A quarter-point hike is not significant enough to overcome other factors pushing up prices. But everyone, including Schiff, still talks about monetary policy as if it operates the way it did before 2008.
It doesn’t.
Before 2008, the Federal Reserve could only lower the federal funds rate by creating new money. It bought government securities from its member banks through open-market operations with newly created money, increasing the supply of money available for lending and thereby decreasing the price of money, i.e., interest rates. Conversely, it could only raise interest rates by destroying money. It would sell government securities to its member banks, decreasing their supply of money and thereby increasing interest rates.
This had an exponential effect on the supply of money available to the public. It both increased the amount of money available for banks to lend and encouraged them to lend it at lower interest rates than they otherwise would. Given our fractional-reserve system, an increase in lending activity by commercial banks increased the money supply beyond the new money created by the Fed.
This is not the way monetary policy works anymore. Due to the large reserve balances held at the Federal Reserve by its member banks—a post-2008 phenomenon—the Fed’s interest-rate and money-supply policies are now separate. The Fed can lower the federal funds rate without creating new money simply by lowering the interest rate it pays on those reserves.
Similarly, it can now raise the federal funds rate without destroying existing money by raising the interest rate it pays on those reserves.
This doesn’t mean Fed rate policy has no effect on the economy, but it has much less effect than it did before. It still influences how many loans commercial banks make and at what rates, but it no longer necessarily accompanies that influence with increases in the monetary base. And while interest rates do affect price levels and investment decisions, increases in the money supply by the Fed have a much larger effect. Consider the following charts:
