We investigate the determinants of US credit union capital-to-assets ratios, before and after the implementation of the current capital adequacy regulatory framework in 2000. Capitalization varies pro-cyclically, and until the financial crisis credit unions classified as adequately capitalized or below followed a faster adjustment path than well capitalized credit unions. This pattern was reversed, however, in the aftermath of the crisis. The introduction of the PCA regulatory regime achieved a reduction in the proportion of credit unions classified as adequately capitalized or below that continued until the onset of the crisis. Since the crisis, the speed of recovery of credit unions in this category following an adverse capitalization shock was sharply reduced.

Regulatory Change and Capital Adjustment of US Credit Unions
IntroductionDuring the 2000s (and especially since the onset of the financial crisis in 2007), the role of capital in minimizing the impact of unforeseen losses on the part of financial institutions has received widespread attention. In this paper we examine the capitalization of US credit unions.Credit unions are non-profit, cooperative financial institutions governed by their membership on a one-member-one-vote basis, with eligibility for membership defined by the credit union's common bond. At the end of 2012, credit unions accounted for approximately 10% of all consumer savings and deposits in the US, servicing over 96 million members drawn from a wide cross-section of society.Unlike other retail financial institutions, credit unions are not permitted to raise capital by issuing new equity. Over time, net worth accumulates through the retention of (tax exempt)earnings that are not distributed to members, in the form of dividends on share accounts, or favourable rates paid on deposit accounts, or subsidized rates charged on loans. 1 This implies capital shortages cannot be rectified quickly, and suggests that the capital adjustment of credit unions may differ from that of commercial banks and non-financial firms.Before 2000 US credit unions were not subject to any formal capital (net worth)requirements. In 1997, the US Treasury recommended that the National Credit Union Association (NCUA), the regulator, introduce specific net worth requirements in the form of 1 The tax exemption affords credit unions a competitive advantage over banks and other mutual financial services providers, and has as...
