An examination of 10 CEFs with the highest duration risk.
Throughout the anemic market and economic recovery, two black clouds have been hanging overhead: rising interest rates and inflation. While no one can predict when, or even if, interest rates will rise (or the effects of inflation), it is important to understand how these scenarios may affect different types of investments.
A few weeks ago, we wrote an article discussing the potential effects that higher interest rates may have on leveraged closed-end funds by raising the cost of leverage. Shortly after this article was published, we were pleased to hear that a number of Nuveen's leveraged CEFs entered into interest-rate swap transactions in an effort to hedge rising leverage costs caused by higher interest rates. (Read the press release for more information.) These funds create leverage by borrowing money at a floating interest rate (payments based on 30-day LIBOR, reset monthly). The interest-rate swap allows the funds to trade the floating-rate interest payments for fixed payments.
A closer look at the Nuveen swaps shows a conservative approach. Generally, each of the 19 funds entered into laddered swap contracts accounting for 75% of total leverage, fixing payments at various rates for one, three, and five years. The fixed payments range between 0.36% and 2.32% per year depending on the length of the contact. In return, the funds will receive floating payments (which is reset monthly) based on 30-day LIBOR. This transaction effectively allows the fund to fix its cost of leverage for a specified period of time. To be sure, current leverage costs will be higher than under the floating-rate scenario, but, should interest rates rise, the funds will be protected from higher borrowing costs in the future.
It's difficult to measure the extent to which a levered CEF is at risk for increasing costs of leverage in a rising interest-rate environment, but we can measure the interest-rate sensitivity of a fund's fixed-income holdings by using duration. Fixed-income CEFs carry duration risk, and, in the case of rising interest rates, investors may face a double whammy of higher costs of leverage and falling net asset values due to the inverse relationship between the market price of a bond and interest rates.
Duration measures the sensitivity of a bond's market price to a change in interest rates. A larger duration indicates higher risk. This means that in the case of rising interest rates, the NAV of a fund with a higher duration will be dragged down further than a similar fund with a lower duration. Of course, a host of factors can effect duration, including the time to maturity, coupon payments, and the magnitude of the interest rate change. And if funds hold bonds to maturity, the drop in price will be recovered as the bonds reach maturity, but many fixed-income CEFs do not hold bonds until maturity.
The table below lists the 10 fixed-income CEFs with the highest leverage adjusted durations. (An adjustment to a fund's reported average weighted duration is made to account for a fund's use of leverage.)
Each of these "high duration" funds has twice the duration risk of the average fixed-income CEF, which sits around 11 years. While this higher level of risk has translated to higher-than-average distribution rates for each fund on the list (the average for fixed-income CEFs is about 7%) it has also translated to higher-than-average premiums. (The average fixed-income CEF is selling at a discount of about 1.5%.) The funds are taking on more risk than most fixed-income CEFs and investors are reaping the rewards, but this will not last forever.
We cover two of the funds appearing on the list: PIMCO Municipal Income
In addition, each of the funds utilizes variable interest-rate leverage. It's clear that investors are set to experience the double-whammy scenario should interest rates rise. Not only will the costs of leverage rise, but the current duration levels point to large market price declines of the funds' underlying holdings, which will hurt net asset value performance.
The above example serves not to demonize PIMCO, but to illustrate the importance of fully understanding the impact of economic forces on any investment's performance. The complexity and nuances of CEFs make this type of analysis even more important. What's more, understanding the parent company and judging its shareholder-friendliness is also important. Nuveen Investments is not the only fund family to use swaps as a hedge against rising interest rates--many have done so recently. And numerous fund families have been redeeming outstanding auction rate preferred shares (which tend to have variable dividend payments based on market rates) for preferred shares that lock in payments or have expiration or call provisions. It is clear that fund families with long-term shareholder value in mind are making changes that will benefit long-term growth, even if current performance is hampered by these decisions.
