The lack of emergency savings can cause financial problems far beyond a short-term cash crunch, new research shows.
Some people without cash reserves end up drawing on their retirement accounts, putting them at risk of shortfalls later in life, according to the Pew Charitable Trusts.
About 13 percent of working-age people with retirement accounts said they had drawn on their nest egg in the previous year and had suffered a financial setback, such as a major car repair or job loss, in the same period, Pew found.
The typical amount of the most expensive financial shock reported was $2,000.
The findings highlight the need for new ways to encourage people to save for unplanned financial jolts, said Alison Shelton, a senior research officer with Pew's retirement savings project.
"There's a need to help people save for the short term," she said.
The report is based on a new analysis of data from Pew's Survey of American Family Finances, focusing on Americans ages 20 to 58 who were not retired and did not have a retired spouse. (The survey, a representative sample of more than 5,600 households, was conducted in 2014 and 2015.)
The ability to use retirement funds prematurely can help people weather cash shortfalls and perhaps avoid cascading financial problems. But, Shelton said, it can also permanently lower retirement savings.
