What Constrains the Federal Reserve? An Interview with Joseph Gagnon

1. Legal limits of Fed power
Basically, the Fed has run out of ammo in terms of language about future policy intentions because it cannot credibly signal its intentions for more than two to three years ahead. It can extend the “late 2014” horizon into 2015, but that is fairly minor.
In terms of the asset purchases, the Fed is limited by law to the Treasury, agency, and agency MBS markets plus foreign exchange. Buying foreign exchange would be viewed as economic warfare by many countries, so it is probably ruled out even though it reflects rank hypocrisy on the part of foreign governments that are massively buying dollars. In the Treasury market, yields on three-year notes are only 0.3 percent, so the Fed must buy five-year to 30-year bonds to have any effect. With the 10-year yield at 1.5 percent, the scope for further effects is modest. Even if the Fed bought every 10-year Treasury, it would be hard to get the yield much below 1 percent, because the risks on such a bond become tremendously skewed toward future losses. There is more scope to buy agency MBS to lower the mortgage rate, but already mortgage rates are at a record low of 3.75 percent. At some point between 2 and 3 percent we are likely to reach the limit. So, the Fed has quite a bit of ammo left, but we can see that it is not inexhaustible.
Research I am doing suggests that it would be much more attractive for the Fed to buy a broad basket of U.S. equities to support the stock market than to try to push down bond yields from these already low levels. Sadly, the Fed is not authorized to buy equities, even though other central banks are allowed to do so.....
I think the average economist outside the Fed thinks the Fed has less ammo than the average economist inside the Fed. I frequently hear people say the Fed has done all it can do. I do not agree, but I do see a limit approaching. Note that that limit arises from legal restrictions on the Fed. If the Fed were empowered to buy all assets, it would never run out of ammo....2. Transmission mechanism needed to create credible expectations
...I fear that announcing a goal of higher inflation, either temporary or permanent, will not actually do anything unless it is backed by actions....3. NGDP Targeting Problems
Some have argued for a price path target or a nominal GDP path target. In that case you do make up for past deviations in inflation. But I think it is difficult to explain to the public how the specific path is chosen. Why should the CPI be 105 in 2013, 107 in 2014, 109 in 2015, and so on indefinitely? People care about the inflation rate not, some arbitrary price level. And it means that after booms you must have deflation. Indeed, if one had started the path in the early 1990s, the late 1990s boom would have put us way above it. Then the Fed would have had to make the 2001 recession much more severe to get us back on the path. That would have been a tough sell politically.4. Expectations
I think it is sensible for the Fed to stick to statements about things it is confident it can achieve, provided that it feels it is doing enough to achieve its objectives. For example, it can talk about purchasing MBS and pushing down the mortgage rate, thus stimulating the economy. The problem is that it has not achieved its objectives over the past three years and its own forecast shows it does not expect to achieve its objectives over the next three years.... I would tend to favor those for which the Fed has direct tools, such as buying foreign exchange to push down the dollar, rather than trying to raise inflation expectations by verbal jawboning.....5. Consolidation
...From the point of view of the United States, what matters is the consolidated government balance sheet (Fed + Treasury),...
