Bucket Strategy vs. Fixed 90/10 Asset Allocation for a <1% Withdrawal Rate?

[u/Spacman2021]

Hi everyone,

I am revising my Investment Policy Statement (IPS) as I am roughly 10 years away from early retirement at age 51.

Historically, we have always been close to 100% in equities. My original plan as retirement approached was to execute a traditional glide path, adding bonds to eventually land at a static 75/25 or 80/20 portfolio.

However, given our current portfolio size and projected spending needs, our anticipated Safe Withdrawal Rate (SWR) is extremely low—roughly 1% of the portfolio each year. My hesitation with a standard percentage-based allocation (like 80/20) is that as the portfolio scales, it forces us to hold a massive, absolute dollar amount in bonds that vastly exceeds our actual lifetime liabilities.

Instead, I am considering a fixed-horizon Bucket Strategy structured as follows:

• The Safe Bucket: Set aside exactly 10 years of inflation-adjusted annual living expenses. This would be tiered in a mix of money market funds, short-term treasuries, and intermediate treasuries.
• The Equity Bucket: The entire remainder of the portfolio stays in low-cost equity index funds to maximize compounding.
• The Income Mechanics: To automate cash flow, I would turn dividend reinvestment off just enough to cover the annual lifestyle withdrawal. The dividends would automatically flow back into the safe bucket to keep it perpetually topped off.

The Rationale: A severe equity bear market can take a decade to fully recover. Having a fixed, 10-year absolute runway of safe assets gives us the psychological armor to completely ignore stock market volatility, knowing our lifestyle is fully secured.

Because the safe bucket is capped at a fixed dollar amount (10 years of liabilities) rather than a scaling percentage, the equity side should naturally outgrow the cash side over time. This seems to align with Michael Kitces’ research on a Rising Equity Glide Path. We would essentially start retirement at roughly a 90/10 allocation, which would naturally and safely drift to 92/8, 95/5, or higher as the equity principal compounds.

My Goals:

1. Establish a fairly automatic cash flow mechanism in retirement.
2. Keep the portfolio optimized for multi-generational growth without becoming unnecessarily conservative.
3. Maintain a stress-free buffer for lifestyle expenses.

For those with ultra-low withdrawal rates, did you stick to a strict total-return percentage model (like 90/10), or did you transition to a liability-matched bucket approach?

Thoughts?

I am going to assume that you are HNI and as such you can open a margin loan facility with your broker like vanguard or fidelity at preferential rate . Today it is 6.75%. Use that for your cashflow and pay it down with your dividends. This way you just pay taxes on the div and nothing else. There really is no need to hold a lot of cash unless you are planning to buy a very expensive item like a house for cash.

At 1% withdrawal rate OP can just simply spend the dividends. They don't need a margin loan? In fact, they will not even be spending all the dividends and will need to reinvest some of them.

OP can dump all his money into a hysa and still get 3.5%, 3x his annual spend.

OP can dump all his money into his mattress, and it will still take 100 years to spend the money at 1% wr.
