When you think of the ultimate financial nightmare, your mind probably jumps straight to October 1929. The Great Depression, an 89% market drop, and breadlines—it’s the gold standard for economic disaster.
But according to William Bengen, the financial researcher who famously created the 4% Rule, if you were planning your retirement, 1929 wasn't actually the worst-case scenario. That "honor" goes to 1968.
Here is why 1968 took the crown as the worst year to retire, and why the lessons from that era are suddenly very relevant in 2026.
The Silent Killer: Inflation vs. Market Crashes
The 1929 retiree faced a massive market crash, but they had a surprising ally: deflation. Because prices actually fell during the 1930s, the "real" value of their remaining dollars went up, and their annual withdrawals actually decreased for several years.
The 1968 retiree had the opposite experience. They were hit by a "one-two punch":
A Stagnant Market: Stocks entered a prolonged bear market that lasted until the early 1980s.
Rampant Inflation: Prices nearly tripled between 1968 and 1983.
"Dealing with inflation is a lot more problematic than dealing with a bear market," Bengen notes in his interview with
. Barron's
By the Numbers: A Tale of Two Retirements
Bengen ran the math using a $100,000 portfolio (65% stocks, 30% bonds, 5% cash) and a 4.66% withdrawal rate:
| Retirement Start | Outcome After 30 Years |
| October 1929 | Portfolio ended at $105,000 (adjusted for inflation). |
| October 1968 | Portfolio hit zero in exactly 30 years. |
The 1968 retiree saw their nest egg lose over half its value in just six years because they were forced to withdraw more and more money every year just to keep up with skyrocketing costs.
Why This Matters in 2026
There are some "uncomfortable" similarities between the 1970s stagflation and our current economic landscape:
Energy Shocks: Much like the oil crises of the 70s, modern oil prices are seeing volatility due to geopolitical conflicts, such as the war involving Iran and disruptions in the
Strait of Hormuz Persistent Inflation: Even before recent conflicts, inflation was consistently hovering above the Fed's 2% target.
Budget Deficits: Massive government spending continues to be a potential inflationary spark.
How to Protect Your Nest Egg
Bengen isn't just looking at the data; he’s adjusting his own strategy. To combat these risks, he has diversified beyond the traditional stock/bond mix:
Gold: He holds 6% of his portfolio in gold as a hedge.
TIPS: He allocates 10% to Treasury Inflation-Protected Securities.
Caution on Stocks: With markets at historic highs, he currently keeps only 35% of his portfolio in equities.
The takeaway? A market crash is scary, but inflation is a permanent tax on your future. If you’re nearing retirement, it might be time to look past the "4% Rule" and ensure your portfolio can survive a repeat of 1968.
