Municipal Market Complexity and New Issue Investing

One of the challenges municipal bond investors face when navigating the municipal bond market on their own, is accessing bonds in the new issue market. The advent of retail order periods for some larger issues has improved retail access. However, both the inherent structure of new municipal bond issues, and the origination process itself, create challenges for retail investors hoping to place small orders for new issues.

Compared to new issues in the corporate bond market, new issues in the municipal bond market are much smaller, and the quantities of bonds available in each maturity can be very limited. This is because municipal bond issues are more akin to a long-term “loan” with a mortgage amortization structure. Each maturity in a municipal bond issue, in essence, is similar to the principal portion of an annual mortgage payment. Much like a loan, the annual debt service (principal and interest payments) is designed to be somewhat consistent over time, as with a home loan or car loan. The result is that municipal bond issues are comprised primarily of a series of consecutive “serial” maturities, in addition to, potentially 1 to 3 longer “term” maturities.

For example, in Arizona earlier this year a $10.85 million City of Tolleson issue included 15 serial maturities due from 2020 to 2034 (with par amounts of only $225,000 to $700,000), and two term maturities in 2036 and 2038. Only the two term bonds had par amounts above $1 million. By comparison, in the corporate bond market, new issues typically only contain a handful of term (or bullet) maturities. This is primarily because corporate bond market yields and prices are tied directly to the most recently issued, comparable maturity, US Treasury bonds. A corporate bond issue can often be limited to some selection of maturities of 2, 3, 5, 7, 10, and 30 years. With a $1 billion average corporate bond issue size, it is rare to have a par amount, in a given maturity, which is below $100 million, while it is common to find maturity sizes of several billion dollars in the largest new corporate issues.
