The Fed is more restricted in which assets it can purchase than other central banks. If we found, I think as other countries did, that they could reach the limits in terms of purchasing safe assets like longer-term government bonds, it could be useful to be able to intervene directly in assets where the prices have a more direct link to spending decisions.
To address the challenges posed by the financial crisis and the subsequent severe recession and slow recovery, the Federal Reserve significantly expanded its monetary policy toolkit. In 2006, the Congress had approved plans to allow the Fed, beginning in 2011, to pay interest on banks' reserve balances.
In the fall of 2008, the Congress moved up the effective date of this authority to October 2008. That authority was essential. Paying interest on reserve balances enables the Fed to break the strong link between the quantity of reserves and the level of the federal funds rate and, in turn, allows the Federal Reserve to control short-term interest rates when reserves are plentiful. In particular, once economic conditions warrant a higher level for market interest rates, the Federal Reserve could raise the interest rate paid on excess reserves--the IOER rate. A higher IOER rate encourages banks to raise the interest rates they charge, putting upward pressure on market interest rates regardless of the level of reserves in the banking sector.
While adjusting the IOER rate is an effective way to move market interest rates when reserves are plentiful, federal funds have generally traded below this rate. This relative softness of the federal funds rate reflects, in part, the fact that only depository institutions can earn the IOER rate. To put a more effective floor under short-term interest rates, the Federal Reserve created supplementary tools to be used as needed. For instance, the overnight reverse repurchase agreement (ON RRP) facility is available to a variety of counterparties, including eligible money market funds, government-sponsored enterprises, broker-dealers, and depository institutions. Through it, eligible counterparties may invest funds overnight with the Federal Reserve at a rate determined by the FOMC. Similar to the payment of IOER, the ON RRP facility discourages participating institutions from lending at a rate substantially below that offered by the Fed.
Our current toolkit proved effective last December. In an environment of superabundant reserves, the FOMC raised the effective federal funds rate--that is, the weighted average rate on federal funds transactions among participants in that market--by the desired amount, and we have since maintained the federal funds rate in its target range.
Two other major additions to the Fed's toolkit were large-scale asset purchases and increasingly explicit forward guidance. Both were used to provide additional monetary policy accommodation after short-term interest rates fell close to zero. Our purchases of Treasury and mortgage-related securities in the open market pushed down longer-term borrowing rates for millions of American families and businesses. Extended forward rate guidance--announcing that we intended to keep short-term interest rates lower for longer than might have otherwise been expected--also put significant downward pressure on longer-term borrowing rates, as did guidance regarding the size and scope of our asset purchases.
In light of the slowness of the economic recovery, some have questioned the effectiveness of asset purchases and extended forward rate guidance. But this criticism fails to consider the unusual headwinds the economy faced after the crisis. Those headwinds included substantial household and business deleveraging, unfavorable demand shocks from abroad, a period of contractionary fiscal policy, and unusually tight credit, especially for housing. Studies have found that our asset purchases and extended forward rate guidance put appreciable downward pressure on long-term interest rates and, as a result, helped spur growth in demand for goods and services, lower the unemployment rate, and prevent inflation from falling further below our 2 percent objective.
Two of the Fed's most important new tools--our authority to pay interest on excess reserves and our asset purchases--interacted importantly. Without IOER authority, the Federal Reserve would have been reluctant to buy as many assets as it did because of the longer-run implications for controlling the stance of monetary policy. While we were buying assets aggressively to help bring the U.S. economy out of a severe recession, we also had to keep in mind whether and how we would be able to remove monetary policy accommodation when appropriate. That issue was particularly relevant because we fund our asset purchases through the creation of reserves, and those additional reserves would have made it ever more difficult for the pre-crisis toolkit to raise short-term interest rates when needed.
The FOMC considered removing accommodation by first reducing our asset holdings (including through asset sales) and raising the federal funds rate only after our balance sheet had contracted substantially. But we decided against this approach because our ability to predict the effects of changes in the balance sheet on the economy is less than that associated with changes in the federal funds rate. Excessive inflationary pressures could arise if assets were sold too slowly. Conversely, financial markets and the economy could potentially be destabilized if assets were sold too aggressively. Indeed, the so-called taper tantrum of 2013 illustrates the difficulty of predicting financial market reactions to announcements about the balance sheet. Given the uncertainty and potential costs associated with large-scale asset sales, the FOMC instead decided to begin removing monetary policy accommodation primarily by adjusting short-term interest rates rather than by actively managing its asset holdings.
That strategy--raising short-term interest rates once the recovery was sufficiently advanced while maintaining a relatively large balance sheet and plentiful bank reserves--depended on our ability to pay interest on excess reserves.
The global financial crisis revealed two main shortcomings of the simple toolkit. The first was an inability to control the federal funds rate once reserves were no longer relatively scarce.
Starting in late 2007, faced with acute financial market distress, the Federal Reserve created programs to keep credit flowing to households and businesses.6 The loans extended under those programs helped stabilize the financial system. But the additional reserves created by these programs, if left unchecked, would have pushed down the federal funds rate, driving it well below the FOMC's target. To prevent such an outcome, the Federal Reserve took several steps to offset (or sterilize) the effect of its liquidity and credit operations on reserves.
By the fall of 2008, however, the reserve effects of our liquidity and credit programs threatened to become too large to sterilize via asset sales and other existing tools. Without sufficient sterilization capacity, the quantity of reserves increased to a point that the Federal Reserve had difficulty maintaining effective control over the federal funds rate.
Prior to the financial crisis, the Federal Reserve's monetary policy toolkit was simple but effective in the circumstances that then prevailed. Our main tool consisted of open market operations to manage the amount of reserve balances available to the banking sector.
These operations, in turn, influenced the interest rate in the federal funds market, where banks experiencing reserve shortfalls could borrow from banks with excess reserves. Before the onset of the crisis, the volume of reserves was generally small--only about $45 billion or so.
Thus, even small open market operations could have a significant effect on the federal funds rate. Changes in the federal funds rate would then be transmitted to other short-term interest rates, affecting longer-term interest rates and overall financial conditions and hence inflation and economic activity. This simple, light-touch system allowed the Federal Reserve to operate with a relatively small balance sheet--less than $1 trillion before the crisis--the size of which was largely determined by the need to supply enough U.S. currency to meet demand.
Looking ahead, the FOMC expects moderate growth in real gross domestic product (GDP), additional strengthening in the labor market, and inflation rising to 2 percent over the next few years. Based on this economic outlook, the FOMC continues to anticipate that gradual increases in the federal funds rate will be appropriate over time to achieve and sustain employment and inflation near our statutory objectives. Indeed, in light of the continued solid performance of the labor market and our outlook for economic activity and inflation, I believe the case for an increase in the federal funds rate has strengthened in recent months. Of course, our decisions always depend on the degree to which incoming data continues to confirm the Committee's outlook.
And, as ever, the economic outlook is uncertain, and so monetary policy is not on a preset course. Our ability to predict how the federal funds rate will evolve over time is quite limited because monetary policy will need to respond to whatever disturbances may buffet the economy. In addition, the level of short-term interest rates consistent with the dual mandate varies over time in response to shifts in underlying economic conditions that are often evident only in hindsight. For these reasons, the range of reasonably likely outcomes for the federal funds rate is quite wide. The reason for the wide range is that the economy is frequently buffeted by shocks and thus rarely evolves as predicted.
When shocks occur and the economic outlook changes, monetary policy needs to adjust. What we do know, however, is that we want a policy toolkit that will allow us to respond to a wide range of possible conditions.
U.S. economic activity continues to expand, led by solid growth in household spending. But business investment remains soft and subdued foreign demand and the appreciation of the dollar since mid-2014 continue to restrain exports. While economic growth has not been rapid, it has been sufficient to generate further improvement in the labor market.
Smoothing through the monthly ups and downs, job gains averaged 190,000 per month over the past three months. Although the unemployment rate has remained fairly steady this year, near 5 percent, broader measures of labor utilization have improved. Inflation has continued to run below the FOMC's objective of 2 percent, reflecting in part the transitory effects of earlier declines in energy and import prices.
The Global Financial Crisis and Great Recession posed daunting new challenges for central banks around the world and spurred innovations in the design, implementation, and communication of monetary policy.
In light of the continued solid performance of the labor market and our outlook for economic activity and inflation, I believe the case for an increase in the federal funds rate has strengthened in recent months. Of course, our decisions always depend on the degree to which incoming data continues to confirm the Committee's outlook.
