How the GATT Rate Changes Your Pension Lump Sum
This post was last updated on January 07, 2025, to reflect all updated information and best serve your needs.
Although defined benefit plans (pensions) are less common today, many people will still rely on them for retirement. There are some very specific rules governing how these plans are calculated for payout either over the course of retirement or in a lump sum.
If you have a pension or are expecting to receive one, then you need to be familiar with the role the Federal General Agreement on Tariffs and Trade (GATT) rate has on your benefits. This is particularly important when deciding if you should take a lump sum payout.

Federal General Agreement on Tariffs and Trade (GATT)
The General Agreement on Tariffs and Trade (GATT) was originally an agreement on trade quotas and tariffs after World War II (hence the name). Over the years, the GATT has evolved and influenced policy across the globe. One of those laws changed how pension lump sums are calculated.
What the “GATT Rate” Is
Long story short, when people say the “GATT Rate,” what they actually mean is 30-Year Treasury Rate.
Technically, the term “GATT Rate” (sometime misspelled as "GAT Rate") is a bit misleading. This refers to a change to the Employee Retirement Income Security Act of 1974 (ERISA) made by the “Uruguay Round Agreements Act” (Public Law 103-465, 103d Congress). There were two key changes relating to lump sum pensions: use of the 30-year Treasury Rate and the Secretary of the Treasury mortality tables.
Why That’s Important
Previously, pensions used different mortality tables and interest rates. This meant that the assumed life expectancy and rates of return used by pension funds were sometimes very different than the new standard. In other words, it’s a pretty big deal.
As an example, if you change the rate of return by one percent (1%) on $500,000 over 20 years, the ending sum changes by $231,087! In 1994 when this change was introduced, there was a 1.75% difference which becomes a change of $649,551!
For companies using the earlier mortality tables and interest rates, this meant they needed to put a lot more money into their pension plans to ensure they were adequately funded. At the time, many plans were underfunded.
To keep the plans funded, employers needed to put substantially more into their retirement funds. By some estimates, plan costs doubled from 1980 to 1996.
What This Means
Without getting too far down this math equation, the lower the interest rate assumptions are, the larger the lump sum should be. The opposite is also true. When interest rates are higher, lump sum payments will decrease.
Therefore, if the 30-year treasury rate is low, you’ll get a bigger lump sum. If rates are higher, you’ll get a smaller lump sum. The smaller your lump sum payout is, the harder it is to create the same level of income your pension would have provided.
This can have a significant impact on your decision to take a lump sum or not.
Risk in Taking a Lump Sum
If you opt for a lump sum distribution, you have to create your own stream of income. Normally this involves building an investment portfolio (stocks, bonds, etc.) or an insurance product such as an annuity. There are other options such as investing in real estate for income as well.
There are risks involved in all of these. Even “safe” investments aren’t bulletproof. In general, the higher expected rate of return, the higher the risk you take on.
If your lump sum is lower due to higher 30-year treasury rates, then you’ll need to earn more on your money. The 30-year treasury rate affects other investments as well, so investment products you invest in could be affected.
Current GATT (30-Year Treasury Rate) and What It Means
When this article was orignally written, “GATT Rate” was 3.18% on July 11, 2022. The 30-Year Treasury rate was rising and now, in January 2024, the 30-year treasury rate is 4.85%, which is slightly higher than the historical average of 4.73%. This means your pension lump sum would be about "average” right now, but vastly lower than it has been over the last few years in our extremely low interest rate environment.
Historical Relevance to Your Lump Sum
The key to look at right now is that pension lump sum calculations will change over time. If you’re nearing retirement, you need to analyze what affect this could have. Keeping track of changing rates is important if you plan to take a lump sum payout.
Current Trends in the 30-Year Treasury Rate
The 30-Year Treasury Rate is set by auction and influenced by many factors. In general, the 30-Year Treasury Rate will change closely with the Federal Funds Effective Rate (FEDFUNDS) set by the Federal Reserve Bank.
To better illustrate this, look at the chart below with the 30-Year Treasury Rate in red and the Federal Funds rate in blue. Notice how closely they move together?
What This Means for Your Pension Lump Sum
We can’t predict the future, but the Federal Rate is highly unlikely to be lower than it has been in recent history. The Federal Reserve had committed to fighting inflation by raising interest rates when this article was originally written. As inflation continued to rise, interest rates were raised accordingly.
When this happens, it means there may be smaller lump sum pension calculations. As of January 2025, the Federal Reserve has stopped raising rates and is currently scheduled to cut rates slightly.
This isn’t anything to be concerned about per se, but you need to know the impact to your pension. Keep in mind that this is only one part of the overall equation. There are many other factors to consider.
Market Conditions
Market conditions can change rapidly. However, not everything is bad. If you can stand the emotional rollercoaster of investing your [theoretically] larger lump sum in the stock market, market downturns have less weight.
The overwhelming evidence shows the stock market will recover and continue to grow. We don’t know what the future holds, but we can anticipate continued long-term growth.
Segmentation Rates and Pension Plan Common Practices
Your pension plan may not follow the GATT rate though. That's because laws are chaning constantly. In practice, many pension plans use "segmentation" rates to calculate your pension lump sum.
Segmentation Rates for Pensions
These segmentation rates are set by the IRS. You can get more information and see the current segmentation rates here. As you can see, there is a slightly higher rate for later segments meaning less credited for later years in your pension.
These "segments" correspond to the number of years between when your retirement or "commencement" date and your life expectancy. As an example, a local company here in Kansas City has segmentation dates split by the first segment of the first five years of retirment, a second segment of years 6 through 20, and a third segment rate is used to discount payments in years 21 and beyond.
In theory, this means people who retire earlier will get a slightly lower lump sum because their payout period would extend beyond 20 years. Bottom line, it's complicated. However, most pension plans now have online calculators so you can regularly check your potential pension payout.
Always check your plan documents for your sepcific situation.
Conclusion and Closing Thoughts
If the decision whether to take a lump sum in lieu of your pension seems complex – it can be. The GATT Rate (30-Year Treasury Rate) and segmentation rates are only some of the factors you want to consider. There are a whole host of other variables in your personal situation.
Given the current 30-Year Treasury rate, lump sums may trend higher or lower into the future. If you’ve been putting off making the decision whether to take a lump sum payout instead of regular pension payments, now is the time to get serious. You might be surprised at how your pension lump sum could change.
You’ll want to weigh all the risks and benefits of your decision carefully. Be sure to consult your financial planner or investment adviser and other financial professionals before making this decision. Check your plan documents and use your pension's online tools to help you decipher what your pension payout might be.
