This paper examines the resilience of various retirement solutions in the context of factors that can influence their sustainability. First, by considering the desirable features of retirement solutions within the United Kingdom, the authors outline the key levers available to the architects of retirement vehicles to ensure stability. Second, to measure “resilience” the authors create a failure score to establish a method of determining if a vehicle has “failed”. Third and finally, we look at those external forces that influence the likely longevity of a retirement solution.
