Given the extremely small probability of default by the GSEs, the expected monetary costs of exposure to GSE insolvency are relatively small — even given very large levels of outstanding GSE debt and assuming that the government would bear the costs of all GSE debt in the case of insolvency. For example, if the probability of the stress test conditions occurring is less than one in 500,000, and if the GSEs hold sufficient capital to withstand the stress test, the implication is that the expected cost to the government of providing an explicit government guarantee on $1 trillion in GSE debt is just $2 million. <br><br> | Given the extremely small probability of default by the GSEs, the expected monetary costs of exposure to GSE insolvency are relatively small — even given very large levels of outstanding GSE debt and assuming that the government would bear the costs of all GSE debt in the case of insolvency.
