The federal student loan machine is a policy dial, not a market force. When the Department of Education flips repayment back on after a pause — or restructures income-driven repayment (IDR) formulas, or clears balances for select cohorts — every downstream effect lands somewhere on a bank's balance sheet. The mechanism is blunt: forty-three million borrowers carry roughly $1.7 trillion in federal student debt, and changes to their monthly cash obligations directly reshape their capacity to service other consumer credit — credit cards, auto loans, personal lines. For the banks that hold those products, servicer policy isn't a D.C. abstraction. It's a credit-quality event.
