Depositories that have a history of investing in passive Treasury and bullet ladders are seeing reinvestment risk pose a real challenge with rates at extreme lows. As shown in the chart below, the average $100 million ladder portfolio reinvested today would yield an average of approximately $2 – $2.2 million less than it would have earned just two short years ago. Could your institution afford that significant of a loss in investment income? Here are some ideas to consider as you seek to mitigate such a drop in investment yield.

Now is the Time to Seek More Competitive Options

Many investment managers are seeking more competitive alternatives, including those with more active management, now that interest rates are at or near zero and reinvestment risk is impairing the bullet ladder’s yield. As credit unions and community banks continue to serve consumers by offering payment deferrals, fee waivers, and other emergency assistance amid a high degree of economic uncertainty, it is becoming more critical than ever to effectively generate income from their investment portfolios.

Spread Becomes Even More Critical in Extremely Low Rate Environments

As an example of one such investment alternative, ALM First often talks about our “Core Spread” strategies which are primarily invested in Agency MBS, Agency CMBS, bank notes and RMBS both fixed and floating (the spread sectors). We also talk about keeping the duration close to home and not making any significant bets on the direction of interest rates. We compare the performance of our actively managed portfolio strategies to passive Treasury and bullet ladders, computing the “excess” returns over time. As margin compression returns and other losses may loom on the horizon, the ability to generate “excess” investment returns and avoid disproportionate reinvestment risk may prove vital.

Let’s look at how a couple of common portfolio structures hold up at differing levels of interest rates. Portfolio A is a 5-year bullet ladder comprised of 20 quarterly maturities of equal weight. Portfolio B is ALM First’s Core Spread model portfolio. Both portfolios have approximately the same duration of 2.50% and the core spread portfolio’s yield is approximately 34 basis points higher that the Treasury ladder. Exhibit 5 summarizes the composition of these two portfolio strategies.

With interest rates now at historic lows, reinvestment risk impairs the bullet ladder’s yield by a disproportionate amount when compared with the Core Spread strategy. For the purposes of this simulation, the two portfolios were both constructed in the first quarter of 2018 and then evolved following the path of rates between then and the first quarter of 2020. The portfolios were then reinvested forward for five years and assumed that rates continued at their current level over that entire period.

The core spread portfolio’s 50% allocation to floaters reset every quarter at a spread of 50 bps over an index, Fed Funds + 10 bps (to normalize LIBOR). The 50% allocation to MBS, evenly split between 15- and 30-year MBS used the yield of the ICE BofA Indices. For the MBS, it was assumed that 4% of the allocation ran off and was reinvested at the next quarter’s index yield.

The simulation for the bullet ladder was more straight forward. Each quarter the shortest rung of the ladder was reinvested at the next quarter’s 5-year yield.

As Exhibit 6 illustrates, the core spread portfolio sees a sharp decline in its yield spread vs the core deposit index in the first quarter of 2020 as the floaters that make up half of the portfolio reset lower following the decline in Fed Funds. But as the portfolios evolve through time, the bullet ladder sees its yield spread fall below that of the core spread as more of the ladder gets reinvested at lower rates compressing its spread. The difference is significant as the bullet spread falls to 35 bps over the core deposit index while the CSP spread stabilizes at 144 bps over the core deposit index. Exhibit 6 further highlights the benefit of investing in assets that provide a spread over rates in times of very low rates. Investors in bullet ladders will see their margins compress as there is no spread cushion to insulate their portfolios from declining rates.  

Over time, any “excess” yield on your institution’s investment portfolio could prove critical to your overall financial performance. This is especially true in today’s uncertain environment as annual budgets for 2020 have already been blown and consumers’ needs – and ability to repay their debts – continue to evolve.
