Liquidity serves as insurance against student loan payment uncertainty

A borrower may choose to hold cash despite a 3.5 percentage point interest rate deficit. The borrower holds $25,000 in cash earning 3.3% interest while carrying $90,000 in student loans at 6.8%. Mathematically, the spread between the savings rate and the debt interest rate favors paying off the loan. However, student loan policy changes with every administration. Future monthly payments may reach thousands of dollars when forbearance ends in 2027. Holding liquid cash preserves flexibility to meet these payments.
