How is the bucket strategy different from a fixed asset allocation?
Neither approach is inherently better. Some retirees prefer having a Safety bucket covering a set number of years of expenses, while others are more comfortable maintaining a fixed percentage in debt throughout retirement. The choice depends on the retiree’s preferences, goals, and financial style.
There are, however, three situations where a bucket strategy can offer distinct advantages over a fixed asset allocation (FAA) approach.
1. Low withdrawal rate + low risk tolerance
Consider a retiree withdrawing only 2% of their portfolio each year. With a low risk tolerance, an FAA approach may lead them to hold a relatively high percentage in bonds. With bucketing, however, even ten years of expenses would represent only about 20% of the portfolio. The retiree can therefore maintain ten years of expenses in the Safety bucket while potentially keeping a larger portion of the portfolio in Growth assets.
2. Strong markets + strong legacy goals
When markets perform well, a bucket strategy can allow excess returns to accumulate in the Growth bucket while the predetermined amount of expenses remains in the Safety bucket. As the Growth bucket increases, the percentage of the overall portfolio held in safer assets can fall. With a fixed allocation, periodic rebalancing brings the portfolio back toward its target percentages. For retirees who are already comfortably funded and have strong legacy goals, these different approaches can produce meaningfully different allocations over time.
3. Irregular future expenses
Bucketing can also make it easier to account for large expenses that occur at specific points in the future. For example, if a retiree expects to purchase a house 15 years from now, the amount needed for that purchase can be incorporated into the bucket strategy. As the purchase gets closer, more of the required funds can move into the Safety bucket. A fixed allocation can be less intuitive for handling expenses with a specific future date.
