The Long View: Bill Bengen - ‘Inflation Is the Greatest Enemy of Retirees’

Why It Matters

The findings recalibrate retirement withdrawal expectations amid higher market valuations and structural market changes, underscoring that modestly higher historical withdrawal rates may not be repeatable and that rising inflation could force major cuts to retiree spending. Investors and advisors should reassess withdrawal frameworks and stress-test plans for valuation and inflation risks.

Summary

Veteran researcher William Bengen discusses A Richer Retirement, his new book that updates and expands his landmark work on safe withdrawal rates. Using expanded historical asset classes — including microcaps, midcaps, international stocks and T-bills — Bengen’s back-tested “safe max” rises to about 4.7% in some samples, but he warns the long-term average has trended lower as stock valuations have risen. He cautions that microcap returns may not be sustained going forward and that portfolio success is tightly linked to current market valuations. Bengen emphasizes inflation as the single biggest threat to retirees and reviews alternatives to a straight inflation-adjusted withdrawal approach, noting trade-offs for fixed-dollar and fixed-percentage methods.
