The most authoritative and relevant evidence comes from the official Federal Reserve Bank of New York's Household Debt and Credit report, which provides direct, primary statistics on student loan balances and delinquency rates. This source indicates a delinquency rate in the vicinity of the stated 16.3%, and corroborates the claim that this level is historically high based on available time series data. Additional support is found in think tank analysis referencing CFPB data, which also frames the rate as unusually elevated and potentially at record highs relative to prior measurements. While other sources offer more commentary than hard figures, they do not contradict the central claim; instead, they reinforce the narrative that student loan delinquency rates have risen sharply and reached unprecedented levels recently. No credible primary or secondary source reviewed presents contradictory data or lower figures that would significantly undermine the statement. Given the alignment between official Fed data and well-regarded independent analyses, it is highly probable the statement is correct.
