Even Static Rates Increase Liabilities, Redington Finds

Assets aren’t only affected when interest rates rise and fall: when they’re static it’s bad news for pension funds too.

(July 3, 2013) — Static interest rates are bad news for pension funds, resulting in a 2.5% increase in liabilities a year, according to research released by UK consultants Redington.

The findings may come as a surprise to some investors, who typically think more bilaterally about interest rates: if they go up I win, down I lose.

Alice Cheung, an associate at Redington, explained there’s more to it than that. The value of a pension fund’s liabilities is calculated using the current yield curve and the implied forward rates.

At the moment, the yield curve is steep, implying that the forward rates are higher than the current interest rates.

This, Cheung said, means that current yields need to move up as projected by the forward rates, just for the liability value to stay constant.

“In other words, in the event that these higher forward rates do not materialise but simply stay constant, the liability value will rise (assuming other factors remain constant), because discounting happens at a lower rate than expected,” she added.

Redington calculated that in a situation where interest rates stay constant, pension fund liabilities would increase by approximately 2.5% a year.

“With little or no hedging, the expected deterioration of a pension fund’s funding position should rates remain at current levels is what we refer to as the rolldown effect,” said Cheung.

“Roll this up over the 10 years or so of the fund’s recovery plan, and this is the pensions equivalent of trying to run up a downward escalator; sweating your assets just to stay in the same place. Now if we factor in market volatility, imagine there’s a guy at the top of the escalator throwing rocks at you.  

“Similarly, when a pension fund is interest rate hedged, the hedge in place would earn the 2.5% carry on the rolldown of the yield curve. A partial hedge would at least lower the incline of the upward climb to full funding.”
