My view is that there is no such thing as a free lunch, not even for governments or central banks. Any action taken may have benefits, but also imposes costs, even if those costs are imposed upon others. So it is for the Fed. At the beginning of 2008, they had a small, clean, low duration balance sheet on assets. Today the asset side of their balance sheet is much larger, long duration, and modestly dirty. Let me give you a few graphs created from the H.4.1 data, obtained via the poorly designed and touchy Data Download Program at the Fed’s H.4.1 portion of their website.
The first graph gives the liabilities of the Fed over the last 4+ years. The data is taken from table 1 in the H.4.1 release. You can see the massive expansion of the liabilities, and the way the crisis unfolded. Currency, and “Other Liabilities & Capital” build “slowly,” i.e. 6.9%/yr and 14.1%/yr, respectively. The US Treasury steps in with the Supplementary Financing Account at a few points where the Fed could use money deposited there for further expansion of quantitative easing, and leaves when they are no longer needed.
But the real growth comes in the “Everything else” which grew at 33%/yr, and reserve balances with Federal Reserve Banks, which you can calculate an annualized rate of growth for, but a rate doesn’t do justice to the process, because it grew due the two events — QE1 & QE2. The Fed bought assets from various parties, who now deposit at banks inside the Federal Reserve System.

The next two graphs come from Table 2 of the H.4.1 report. These describe the assets that have a maturity, which comprise over 80% of the Fed’s assets over the time of the graph, and over 90% at present. First, you can see the growth of the assets bought through QE, Treasuries, Agencies, and MBS. Second, you see the crisis responses: 1) the loan programs in the US, which explode and trail away and 2) the Central Bank Liquidity Swaps, which explode, trail away, and have come back in what is presently a muted form today.
Perhaps the bigger change is that the Fed’s balance sheet has a lot more long-maturity assets than it used to. This stems from the quantitative easing they have done, as well as their efforts to
play God flatten the Treasury yield curve.
Now, almost all of the assets underlying everything 10 years and shorter pay out their principal all at the end, with no right of prepayment. For 10 years and longer, at present 75% are Mortgage Backed Securities [MBS]. Those have average lives (weighted average time for payment of principal) considerably shorter than a bond that pays all of its principal at the end for three reasons:
- Principal gets paid down slowly due to normal amortization.
- Prepayments get made when it is advantageous to the borrower, which not only pays off principal today, but shortens the term of the loan, which accelerates the normal repayment of principal.
- The final maturity of of the longest loan in the pool is the final maturity of the pool
So, in terms of actual interest rate sensitivity, the over 10 years bucket is probably only a little more sensitive to change in rates than the 5-10 year bucket.
In normal times, central banks buy only government debt, and keeps the assets relatively short, at longest attempting to mimic the existing supply of government debt. Think of it this way, purchases/sales of longer debt injects/removes liquidity for longer periods of time. Staying short maintains flexibility.
Yes, the Fed does not mark its securities or gold to market. Under most scenarios, it is impossible for a central bank which can issue its own currency to go broke. Rare exceptions — home soil wars that fail, orpolitical repudiation of the bank, where the government might create a new monetary standard, or closes the bank because of inflation. (Hey, the central bank has been eliminated twice before. It could happen again.)
The only real effect is on how much seniorage the Fed remits to the Treasury, or, if things go bad, how much the Treasury would have to lend/send to the central bank in order to avoid the bad optics of negative capital, perhaps via the Supplemental Financing Account. This isn’t trivial; when people hear the central bank is “broke,” they will do weird things. To avoid that, the Fed’s gold will be revalued to market at minimum; hey maybe the Fed at that time will be the vanguard of market value accounting, and revalue everything. Can you imagine what the replacement cost of the NY Fed building is? The temple in DC?
Or, maybe the bank would be recapitalized by its member banks, if they are capable of doing so, with the reward being the preferred dividend they receive.
Back to the main point. What effect will this abnormal monetary policy have in the future?
1) Growth strengthens and inflation remains low. In this unusual combo, it will be easy for the Fed to collapse its balance sheet, and raise rates. This is the dream scenario; and I don’t think it is likely. Look at the global economy; there is a lot of slack capacity.
2) Growth strengthens and inflation rises. The Fed will likely raise the interest on reserves rate, but not sell bonds. If they do sell bonds, the market will back up, and their losses will be horrible. If don’t take the losses, seniorage could be considerably reduced, or even vanish, as the Fed funds rate rises, but because of the long duration asset portfolio, asset income rises slowly. This is where the asset-liability mismatch bites.
If the Fed doesn’t raise the interest on reserves rate, I suspect banks would be willing to lend more, leaving fewer excess reserves at the Fed, which could stimulate more inflation. Now, there are some aspects of inflation that remain a mystery — because sometimes inflationary conditions affect assets, rather than goods, I think depending on demographics.
3) Growth weakens and inflation remains low. This would be the main scenario for QE3, QE4, etc. We don’t care much about the Fed’s balance sheet until the Fed wants to raise rates, which is mainly a problem in Scenario 2.
4) Growth weakens and inflation rises, i.e. stagflation. There’s no good set of policy options here. The Fed could engage in further financial repression, keeping short rates low, and let inflation reduce the nominal value of debts. If it doesn’t run wild, it could play a role in reducing the indebtedness of the whole economy, though again, it will favor debtors over savers. (As I’ve said before, in a situation like this, or like the Eurozone, all creditors want to be paid back at par on the bad loans that they have made, and it can’t be done. The pains of bad debt has to go somewhere, where it goes is the argument.)
I’ve kept this deliberately simple, partially because with all of the flows going back and forth, and trying to think of the whole system, rather than effects on just one part, I know that I have glossed over a lot. I accept that, and I could be dead wrong, as I sometimes am. Comment as you like, with grace and dignity, and let us grow together in our knowledge. I’ve been spending some time reading documents at the Fed, trying to understand their mechanisms, but I could always learn more.
During older times, the end of a Fed loosening cycle would end with the Fed funds rate rising. In this cycle, it will end with interest of reserves rising, and/or, the sale of bonds, which I find less likely (they will probably be held to maturity, absent some crisis that we can’t imagine, or non-inflationary growth). But when the tightening cycle comes, the Fed will find that its actions will be far harder to take than when they made the “policy accommodation.” That has always been true, which is why the Fed during its better times limited the amount of stimulus that it would deliver, and would tighten sooner than it needed to.
But under Greenspan, and Bernanke to a lesser extent (though he persists in pushing the canard that the Fed was not too loose 2003-2004, ask John Taylor for more), there were many missed opportunities to stop the buildup of bad debts, but the promise of the “Great Moderation” beguiled so many.
Removing policy accommodation is always tougher than imagined, and carries new risks, particularly when new tools have been used. Bernanke can go to his carefully chosen venues and speak to his carefully chosen audiences, and try to exonerate the Fed from well-deserved blame for their looseness in the late 80s, 90s, and 2000s. Please, Mr. Bernanke, take some blame there on behalf of the Fed — the credit boom could never have happened without the Fed. Painting the Fed as blameless is wrong; the “Greenspan put” landed us in an overleveraged bust.
I’m not primarily blaming the Fed for its current conduct; today, it is trying to deal with a lending bust — too much debt, and much of it is bad, with a government whose budget is out of balance. (In the bust, there are no good solutions.) I am blaming the Fed for loose policies 1984-2007, monetary policy should have been a lot tighter on average. But now we live with the results of prior bad policy, and may the current Fed not compound it.
