What is a Pension Obligation Bond?

Bottom Line Up Front

• Tight municipal budgets and rising pension costs have led some towns to consider Pension Obligation Bonds (POBs) as a funding strategy.
• POBs can improve a plan’s funded status and offer temporary budget relief if investment returns exceed borrowing costs, but that outcome depends heavily on market performance and timing.
• Significant risks remain: poor investment returns, added debt, and shifting costs to future taxpayers can leave municipalities in a worse financial position than before issuance

Many towns and cities today are operating under increasing fiscal pressure. Rising costs, slow revenue growth, and competing demands on limited resources have made it harder than ever to balance municipal budgets. At the same time, long-term obligations such as pension liabilities continue to grow, placing additional strain on financial stability. In response, some municipalities have turned to Pension Obligation Bonds (POBs) as a strategy to address these challenges.

What is a Pension Obligation Bond?

A Pension Obligation Bond is a taxable bond issued by a municipal entity to help fund the unfunded portion of its pension liability. The municipality issues the bond and invests the proceeds alongside the pension plan’s existing assets, typically in higher-yielding investments.

The goal is to earn a rate of return on those invested proceeds that exceeds the interest rate owed on the bond over its term. If that occurs, the municipality can improve its pension funding status and potentially reduce its long-term costs. However, the strategy also introduces additional financial risk.

The Government Finance Officers Association (GFOA) has cautioned municipalities against using POBs in most circumstances. In its official advisory, the GFOA cites the inherent risks of market volatility, timing uncertainty, and added debt burden. While POBs can appear beneficial on paper, they often increase overall financial risk if investment returns fall short of expectations.

Why Consider Pension Obligation Bonds?

Municipalities typically explore POBs for two primary reasons: budget stabilization and potential financial upside.

1. Budgetary Relief

Many local governments are operating under tight budgets and are forced to prioritize limited resources. Issuing debt to fund part or all of the pension liability can temporarily relieve pressure on annual budgets. This may stabilize required pension contributions and free up funds to support other essential public services.

2. Potential Financial Advantage

In theory, municipalities can borrow at a relatively low, fixed interest rate and invest the proceeds in assets expected to earn a higher return over time. If the pension investments outperform the bond’s interest rate, the municipality may realize a net gain.

However, these benefits depend on favorable market conditions and long-term investment performance. If those assumptions don’t hold, the financial outcome can quickly turn negative, leaving the municipality in a worse position than before the bonds were issued.

The Risks

While POBs can offer short-term relief and potential long-term benefits, they are not a cure-all. These transactions carry several significant risks that municipalities should thoroughly consider before proceeding.

1. Investment Risk

The greatest risk is that investment returns fail to exceed the bond’s interest rate.

For example, if a city issues bonds at a 5% interest rate and expects its pension assets to earn 7%, the 2% spread seems advantageous. But market performance is unpredictable, and a few years of underperformance can quickly erase those gains.

It is also important to remember that POBs are taxable instruments. This means issuers pay taxable market interest rates which increases the hurdle rate for the pension fund’s investment returns to exceed the taxable bond’s interest rate to achieve the desired advantage. Because POB proceeds are typically invested immediately, issuing bonds during an overvalued market can magnify the downside if asset values decline soon after.

2. Timing Risk

Timing is critical as POBs tend to be most effective when interest rates are low and market conditions are favorable. However, predicting either is challenging.

Municipalities are often drawn to POBs after periods of strong market performance, when the potential for future underperformance is higher. Conversely, when interest rates are high, borrowing costs increase and the “spread” between the bond rate and expected investment returns narrows. This can undermine the core financial logic behind the transaction.

3. Credit Rating Risk

Credit rating agencies typically view POBs with caution. While a POB may improve a plan’s funded status on paper, it also adds a fixed debt obligation to the municipality’s balance sheet.

This can be seen as a sign of fiscal stress or an attempt to leverage future resources, which may result in a credit rating downgrade. Such a downgrade increases borrowing costs for future projects, offsetting much of the anticipated savings.

4. Shifting Costs to Future Tax Payers

A key concern from a public policy perspective is intergenerational equity. This means the fair distribution of costs between current and future taxpayers.

Issuing POBs can transfer risk to future residents if investment performance falls short of expectations. While today’s taxpayers may experience short-term relief, future taxpayers could be left paying off the debt for assets that failed to meet return assumptions.

This outcome is particularly troubling when POBs are issued primarily as a short-term budget solution rather than as a part of a comprehensive, disciplined pension funding strategy. In such cases, the municipality is effectively kicking the can down the road and betting that future market conditions will deliver enough return to bail it out.

Conclusion

On the surface, Pension Obligation Bonds can seem like an attractive shortcut to improve pension funding and ease budget pressures. LIke any investment tool, there is a place for them when used appropriately. However, the GFOA generally advises against POBs unless paired with structural reforms and strict funding discipline.

If your municipality is considering a POB, it’s essential to:

• Use realistic actuarial and investment assumptions
• Conduct robust scenario and stress testing
• Commit to long-term funding discipline to avoid repeating past shortfalls

It is also important to consider whether your municipality may require State approval or changes in local ordinances to allow for the issuance of a POB. To improve the odds of success on your POB issuance, it’s recommended that you obtain the required permissions so that you can “strike while the iron is hot” to take advantage of that period of low interest rate or equity market declines.
