On the Specialness of Long Treasuries

When Gary Schilling presented to the Baltimore CFA Society, he made the comment about how much bonds beat stocks by.? His proxy for bonds was 25-year zero coupon bonds.? Invest in those from 1980 to the present, rolling to the new 25-year regularly, and yeah you can beat stocks handily when interest rates fall and continue to fall.

Think of what a 25-year zero coupon Treasury means.? The price measures how much you are willing to discount inflation and nonexistence of the US government 25 years from now.? When interest rates fall 3% for a 25-year zero, the value of the bond more than doubles.? Falling almost 12% in yield since the peak, that multiplies the value of the bond more than 16 times, far more than the equity market over a similar period, including dividends.

But wait.? How many people would have the stomach to make such a trade even if they were mostly convinced that rates would fall so much?? Few, I think.? The more volatile the investment, the fewer the people who follow through. People lose confidence during extended slumps.? Schilling and Hoisington may have had the courage to do it, but few others did.

The same applies to a 100% equities portfolio.? Few can stomach that level of volatility.

But when one compares bonds to stocks, be careful what you allow to be the bond proxy.? Personally, I would choose the Lehman Barclays’ Aggregate — it’s a good proxy for the investment grade bond market, and there is nothing special about it — it has all risks, and an average level of interest rate sensitivity.? It has done well over the last 30 years, but has not beaten stocks.? Over the last ten years, yes, it has beaten stocks.? But that is normal.? Stocks have bad decades, every three decades or so.? In those decades, bonds often do better.

If one uses 30-year Treasuries, rolling them over the last 30 years, you end up with an incredible result. Not quite as good as 25-year zeroes, but still good enough to beat the S&P 500 with dividends.

What I am arguing is that choosing the narrow area of the bond market that did best over the last 30 years — highest quality noncallable long debt, is not a fair comparison against the stock market as a whole.? We should use the investment grade bond market as a whole, and that means the Barclays’ Aggregate [AGG].

Let me put it this way, if someone can pick the best performing index of bonds to compare against stocks, what is to keep the stock manager from picking the best sub-index of stocks to be the policy comparison?? Hindsight is 20/20, so let’s limit the comparison to broad indexes.

  1. I seriously doubt this US government will still exist in 25 years. Please think carefully before you make a reply to that statement.

    There is still a government in Rome after the Roman Empire collapsed. The French empire is gone, still a government in Paris. British Empire is now a tourist attraction/wedding event, but still a government in London.

    But not the same governments. All of them were able to print currency (but not wealth).

    Uncle Sam owes $16 trillion “on balance sheet”, plus another $50 trillion in off balance sheet promises.

    They are now running trillion dollar a year spending deficits, and after increasing debt by 10% of GDP per year, GDP is growing a mere 2% per year.

    If investors looked at history, the odds are zero that this government will last.

    There will be a government in Washington, just like Rome or Paris or London. But it will be a different government. This government is bankrupt.

    *IF* you bought 25yr zeroes back in 1982 (a very big IF), you were implicitly making a bet that Paul Volcker would slay inflation, leaving “real” (after inflation) returns of 12%+/yr. Obvious success in 20/20 hindsight, but the markets were betting the opposite at the time.

    If you are buying long treasuries right now, you are betting that Bernanke will magically increase real returns from NEGATIVE 3% to something with a plus sign, and he is going to do this without raising interest rates?

    That isn’t investing. That is numerical illiteracy.

    The US government is actuarially bankrupt, and we are all standing around trying to guess when it will be cashflow bankrupt.

  2. Bonds have been in a secular bull market from the mid-1980’s to present, so the Schilling study result is not surprising. the real test would be to see how the 1950-1985 period behaves i.e. during a prolonged bond bear market.
