Sidecar savings could increase workers’ financial wellbeing today, and in retirement, says Nest Insight

Nest Insight has today, 18 September 2017, published a discussion paper, Liquidity and sidecar savings (PDF). The paper sets how, thanks to auto enrolment, millions of people are starting to build up meaningful retirement savings to help them achieve a more comfortable later life. However, in contrast, many of these people, particularly those with lower and moderate incomes, don’t have enough in liquid savings to manage financially on a daily basis.

The report outlines how a lack of liquid savings leaves people at risk of financial shocks which can have a severe impact on their lives, both in the short term and through into their retirement years.

Liquidity and sidecar savings discusses possible solutions to this liquid savings challenge, concluding that hybrid products, such as the sidecar savings model, could hold the answer.

Will Sandbrook, executive director of Nest Insight said:

“With so many people now saving into a pension, some have suggested that the defined contribution (DC) system should be opened up to some level of early access. The idea being that if an individual has access to enough liquid savings they’re more likely to avoid damaging financial shocks, and the benefits of this could be felt right through into later life.

“However, simplistic early access models have a number of design issues and create the risk that an excessive amount of money could be withdrawn from pension pots pre-retirement.

“An alternative option could be to create a hybrid solution, like the sidecar model, which feels like a single product to the consumer yet has separate savings jars below the surface. This method would allow the pension pot to remain locked up, and invested for the long term, while giving savers access to an amount of liquid savings via a sidecar account.

“There are many possible benefits to this approach. The model has the potential to improve the financial wellbeing of many Nest members, and other DC savers, who are on lower and moderate incomes. However, a number of questions remain about how it might work in practice. That’s why we’re working in partnership with Professor Brigitte Madrian, at Harvard Kennedy School, and the Money Advice Service to construct an academic research trial. We aim to start trialling the idea next year and, as with all our research, we’ll make the results widely and freely available to maximise their reach and the potential benefit to savers.”

Nick Watkins, head of insight and evaluation at the Money Advice Service says:

‘Our research consistently highlights problems that can be caused by the lack of a savings buffer. We know that unexpected bills can and do happen, and that all too often people have to resort to using high-cost credit or borrowing from friends and family. One of the Financial Capability Strategy priorities is to explore ways in which we can help people to put money aside, especially working families on modest incomes. The idea of a default programme that makes it easy to automate savings is very appealing and we look forward to exploring how this could work for UK consumers.’
