Short Term Treasury Portfolio: how to retire safely

Last Update: 30 April 2023

The Short Term Treasury Portfolio invests in 1 asset class and can be suitable for a retirement plan.

In this post we will find out the most affordable withdrawal strategies for the Short Term Treasury Portfolio. All calculations are made on actual historical series.

Key Points

The Short Term Treasury Portfolio is allocated for 0% on Stocks.

In the period Jan 1871 - Apr 2023, the portfolio granted a 4.43% annualized return, with a -8.52% maximum drawdown.

Worst case scenario so far, over a 30-year time horizon, you could have withdrawn 2.339% of your initial capital each year, kept withdrawing all the time (adjusting for inflation), and you wouldn't have run out of money before 30 years.

With a 4% withdrawal strategy, you would have lived on your investiment for 30 years in the 60.25% of cases, and for 50 years in the 16.84% of cases

You can implement the portfolio, let it passively follow the market trend, and in the meantime you can periodically withdraw a portion of it for your retirement.

The Short Term Treasury Portfolio

The Short Term Treasury Portfolio contains 100% Bonds.

Weight Asset Class Category
100.00 % US Short Term (1-3y) Treasuries Fixed Income

Over the last 30 years (last update: April 2023), the portfolio has returned 3.03% annualized, with a maximum drawdown of -5.36%.

4.286% has been a safe withdrawal rate.

Let's consider different timeframes, all ending at April 2023: which Withdrawal Rates could you have applied without running out of money in your retirement?

The Withdrawal Rates calculated here are annualized and refer to the initial capital (not the current!). The first month withdrawal is 1/12 of that annualized withdrawal and it's adjusted for inflation for each subsequent month.

A Perpetual Withdrawal Rate (PWR) protected the original inflation adjusted capital.

A Safe Withdrawal Rate (SWR) didn't protect the original capital, but the portfolio didn't run out of money during retirement. The portfolio went to zero exaclty at the end of the retirement period.

Withdrawal Rates Simulation (updated at Apr 2023)

During your retirement, tipically you want to divest periodically some amount of money from your portfolio, without running out of money over a long period.

Based on how long your retirement is, what would it be an acceptable withdrawal rate, for the Short Term Treasury Portfolio?

▼ Methodology and Definitions
The algorithm calculates the chance of success of a initial withdrawal rate, whose amount in dollars is adjusted monthly for inflation. The algorithm tries a retirement simulation, starting at every possible month in the given period.
For instance, assuming a 20 years retirement, the algorithm will cover each 20 year timeframe starting at every possible month in the given period between the start and end month.

Here's how simulations work (each simulation is based on actual asset class returns, in US dollars):
  • At the beginning, you start with a certain amount of money invested in the portfolio (i.e. the initial invested capital).
  • Each month, money is withdrawn from the portfolio. The withdrawal rate is calculated based on the initial withdrawn, annualized.
  • Each month, portfolio value is updated, based on the asset classes returns (dividends are supposed to be reinvested).
  • Each month, portfolio is rebalanced, to reset to the original weight of the assets (applicable only if portfolio contains at least 2 assets).
  • Each month, the withdrawal is adjusted for inflation (US Inflation is used for simulation).
The Withdrawal Rates calculated here are annualized and refer to the initial capital (not the current!). The first month withdrawal is 1/12 of that annualized withdrawal and it's adjusted for inflation for each subsequent month.

The Perpetual Withdrawal Rate (PWR) is the percentage of the initial portfolio balance that can be withdrawn at the beginning of each month with inflation adjustment, preserving the original invested capital, adjusted for inflation too. In this website, you can find PWRs with 100% Capital Protection, or less.

The Safe Withdrawal Rate (SWR) is the percentage of the initial portfolio balance that can be withdrawn at the beginning of each month with inflation adjustment, without the portfolio running out of money. In this website, you can find SWRs with 100% Success rate, or less.
