Why Long Safety Buckets Don't Require 70% Debt

One of the biggest criticisms of bucketing is that it forces retirees into overly conservative portfolios. A safety bucket holding 10 years of future expenses, for example, is often dismissed as requiring an unacceptably high allocation to debt. In reality, the answer is far more nuanced.

A bucket strategy can certainly become too conservative if it attempts to fund all future spending from safe assets. But it doesn't have to. The required allocation to the Safety Bucket depends not only on the number of years being protected, but also on how much of the retiree's spending those assets are expected to cover.

Consider a retiree with a 3% initial withdrawal rate. If only essential expenses are covered by the Safety Bucket while discretionary expenses remain invested in the Growth Bucket, the numbers change dramatically. Even with a Safety Bucket capable of funding 30 years of essential expenses, the initial allocation to safer assets may be only 40% of the portfolio—not 70% as many assume.

Ironically, a retiree following a traditional fixed asset allocation may end up holding 70% in debt throughout retirement, sacrificing a substantial amount of long-term growth. A well-designed bucket strategy, by contrast, can provide decades of spending security while keeping a majority of the portfolio invested for growth.

The lesson is simple: the size of the Safety Bucket should not be judged solely by the number of years it covers. Equally important is which expenses it covers. By limiting the Safety Bucket to essential expenses and allowing discretionary spending to remain invested in growth assets, retirees can achieve an attractive balance between safety and long-term portfolio growth.
