Designing Stress Scenarios for Pension Fund Solvency

Summary

The document considers how to build forward-looking financial stress scenarios for assessing pension fund solvency. The proposed shocks include a lower discounting curve, reduced returns on equities and property, and weaker credit bond returns that vary by rating. These scenarios focus on how changes in discount rates and asset performance may affect a fund’s financial position.

The response recommends adding scenarios with clear narratives to support discussion with trustees: a hard Brexit or Eurozone breakup for European portfolios, deflation and its effects on indexation, rates, and equities, and a crisis in emerging markets. Historical episodes such as the Asian or Mexican peso crises are offered as reference points for studying market reactions. The document provides scenario ideas rather than calibrated shock magnitudes, probabilities, or portfolio-specific impact estimates; an infinite range of scenarios is possible, so selections should fit the fund’s exposures and purpose.

Key ideas

• Stress tests can combine discount rate shocks with weaker returns across major asset classes.
• A scenario narrative can help trustees discuss how a shock might affect the fund.
• European portfolios may warrant tests for a hard Brexit or a breakup of the Eurozone.
• Deflation scenarios should consider interest rates, equity markets, and pension indexation.
• Emerging-market crises can be informed by studying historical episodes.

I am working on an analysis to estimate financial risks, especially for pension funds.

More specifically, I am trying to define some stress scenarios which could have an affect on the solvency of a pension fund. I am looking three years into the future for this analysis.

I have come up with the following scenarios:

- Lover discounting curve: The ultimate forward rate will be reduced from 4.2 to 2.2 percent.



- Lower returns 2: Returns on equity and property is reduced to 0 percent while credit bonds are reduced with 0.5 - 2 percentage points dependent on credit rating.



Are these stresses sound? Are there other likely scenarios, which could be interesting to examine?

The number of scenario's I could come up with is infinite, these 3 seem interesting and give a backstory which can make discussions with trustees easier:

If you're invested in Europe, I would definitely consider a hard Brexit or Eurozone breakup scenario where European assets are harder hit than other assets. Depending on who you ask these scenario's are not probable but can happen.

Another thing to consider is a deflation scenario, what happens with pension indexation in that scenario. What happens to the interest rates and equities then?

Developing market crisis, for example: a repeat of the Asia crisis or the Mexican peso crisis. How did markets respond back then?
