A liquidity coverage ratio is a bank industry measurement assessing the adequacy of short-term liquidity of large banks under runoff stress scenarios over a 30-day period.  Credit unions as a rule are not subject to LCR, but benchmarking to banking standards can be a prudent way to measure financial stability.

According to an independent study by consulting firm CliftonLarsonAllen, the LCR for the $29.1 billion State Employees' Credit Union based in Raleigh, N.C., is 20 times the minimum banking requirement. The study, which also measured SECU's risk-based net worth, is another in an ongoing series of independent evaluations the credit union is undertaking in preparation for revised NCUA capital requirements and stress tests for larger credit unions slated for February 2015.

"Based on my review, the methodology applied by SECU in determining their LCR ratios under base and stressed scenarios is in compliance with the guidance provided by the bank regulators," Bryan W. Mogensen, assurance principal for CliftonLarsonAllen said.
