In a previous post, I described a paper on sovereign debt by Mattia Landoni (Cox School of Business – Southern Methodist University), Christopher Cameron (US Treasury), and me. Our paper gives a simple way to relate debt management policies and goals. We were very excited that it was accepted for the OECD‘s first Public Debt Management Conference in Paris last month. Mattia graciously consented to visit Paris and present for us (second or third row, left of center, facial hair, glasses, no tie). He reported that “the Dutch State Treasury Agency explained that they had already had the same intuition over 10 years ago”, and that our work was “the perfect theoretical underpinning” for their approach. Mattia was impressed with the high quality of the conference and the discussions. We are grateful for the feedback that will improve our paper.
QWAFAFEW* Denver meets September 12th with a discussion on alternative factor investing! Please RSVP now.
Event Details and Location:
We will meet at the Cactus Club in Denver, located at 1621 Blake St, starting at 5:30pm. Our format will allow ample time for networking both before and after the presentation.
The explosion in alternative data has been both a blessing and a curse to investment managers. Many more data sources have become available, thus expanding the opportunities for uncovering new sources of alpha. At the same time, the risk of wasting time on data issues or other dead ends has also increased. George Bonne from MSCI will join us to lead a discussion on the “alternative dataset” landscape and how investors are incorporating these tools, highlighting areas where research has indentified factors that add marginal explanatory power beyond traditional factors.
About Our Speaker
George Bonne, PhD, PRM joined MSCI in 2016 as Executive Director of Equity Factor Research, where he and his team work to create new and innovative factors to be used in MSCIs analytics and index products. Current projects involve exploring alternative and big data, exploring machine learning in factor construction and other areas, and investment crowding.
If you’re in Denver on May 23 and you’re interested in the bond market, join us for a QWAFAFEW* talk: Predicting the Supply of Long-Term Bonds. The talk will be based on a new paper by Mattia Landoni, Chris Cameron, and myself. RSVP here. I hope to see you there!
Mattia Landoni (SMU Cox School of Business) and I recently completed a paper on bond portfolio dynamics (now under review at an academic journal). We offer a new theory on the evolution of the maturity structures for rolling bond portfolios inspired by population mathematics, with new tools for evaluating and optimizing government borrowing strategies. The working paper is available at SSRN (free registration required), or you can contact either of us and we will gladly send you a copy.

Today, the Alphaville section of the Financial Times published The invisible run-off, in which I discuss a new source of “quantitative tightening” that almost no one seems to have noticed. I estimate that $350 billion of private funds will be absorbed when the U.S. Treasury refinances its securities that are now in special accounts for state and local government bonds. The Treasuries are currently held in escrows to secure municipal bonds that have been “advance refunded.” An advance refunding is a complex refinancing technique for bonds that are months or years away from their first scheduled call date.
The Tax Cuts and Jobs Act prohibits advance refundings going forward because they increase the supply of tax-exempt bonds (at least until the old bonds are called), thereby shaving the revenue to the Treasury.
According to the Joint Committee on Taxation, the end of advance refundings will save the federal government $17 billion over the next ten years:
Of course, that’s not much in comparison to the overall projected effect of tax reform:
Over the next few years, perhaps $350 billion in escrow Treasuries will mature. These will have to be refinanced without the help of new advance refundings. The run-off from escrows is not as large as the Fed’s expected balance sheet reduction (as much an obsession to the markets as a sizzling steak to a dog), but the escrow wind-down could match about a third of the Fed’s roughly $1 trillion planned disposal of Treasuries. The loss of escrow funding to the Treasury, and the additional supply to the market, could be prove significant.
The key to the $350 billion estimate for escrow securities was the S&P Municipal Bond Prerefunded/ETM Index. The index includes about $190 billion in bonds that have been escrowed to a call date (“ETC”) or to escrowed to maturity (“ETM”). I scaled up the prerefunded bonds by taking the ratio of the whole S&P municipal bond universe ($2.2 trillion) to the full reported size of the municipal market ($3.8 trillion).
I was interested to see that the average coupon of the prerefunded bonds in the index is 4.9%. This seems to confirm the prevalence of 5% coupons in recent years. These high coupons (their yield is now 1.6%) were among the most attractive candidates for refunding.
The escrow Treasuries generally have much lower coupons than the refunded bonds they support, so more than $1 in Treasuries are needed to cover the interest payments on each $1 of refunded bonds. This relationship implies that $350 billion could be a conservative estimate for Treasuries in advance refunding escrows. On the other hand, some of the escrows are so short that they are considered to be “current refundings” instead of advance refundings. Current refundings are still allowed, but their short shelf life has probably limited their impact on the index. To the extent that some bonds in the index correspond to current refundings, the $350 billion estimate could be on the high side. Another distortion would be if the prerefunded share of the S&P index universe does not match that of the whole market.
Addendum added January 21, 2018
The Wall Street Journal just published a letter of mine, Debt Bomb has Shorter Fuse Than Many Citizens Think (credit to them for the snappy title, and to my wife Corrina for invaluable editing). I respond to the Journal’s recent editorial Obama’s Debt Interest Bomb.
The editorial warned of a growing burden of interest payments on the national debt, due to rising interest rates and the anticipated drawdown of the Fed’s portfolio of Treasury securities. In my letter, I point out that the problem is exacerbated by two factors. First, the short maturity structure of the Treasury’s debt offers little protection against higher interest rates.
The second factor is the uneven composition of the securities held by the Fed. The Fed neutralizes the interest payments it receives by returning them back to the Treasury. Because the Fed tends to hold the Treasury’s higher-rate securities, the Treasury will sorely miss the Fed’s subsidy when it’s gone.
