Yield Maintenance

Yield Maintenance: What the Market Actually Requires

Yield maintenance is the fixed-rate lender's insurance policy, and it behaves like a bond. When market yields fall after closing, the penalty balloons, because the lender needs more money today to replicate the high coupon it is losing. When yields rise, the penalty shrinks toward its floor, almost always 1% of the outstanding balance. Life insurance companies use yield maintenance nearly universally because their loans back long-dated liabilities. Agency lenders make it the default on fixed-rate multifamily paper. Banks apply it selectively on fixed-rate portfolio loans. One drafting detail moves real money: whether remaining payments are discounted at the Treasury yield flat or at Treasury plus a margin. Discounting at Treasury flat produces a larger penalty, so borrowers should push for Treasury plus 50 basis points in the note.

Against defeasance, the economics are similar in spirit, both make the lender whole, but the mechanics diverge. Yield maintenance is cheaper when the loan balance is modest or the remaining term is short, because defeasance carries $60,000 to $100,000 of fixed transaction costs for consultants, counsel, securities brokers, and rating agency confirmations regardless of loan size, while yield maintenance is simply a check at closing. It is also faster: a yield maintenance payoff can close in days, while defeasance takes 30 to 45 days. Defeasance wins when Treasury yields sit above the note rate: the replacement securities then cost less than the loan balance, so the effective premium can fall to zero or below, while yield maintenance never drops beneath its 1% floor.

CMBS does not use yield maintenance, for a structural reason. A securitized loan sits in a REMIC trust whose bondholders bought a precise schedule of cash flows, and an actual prepayment, even one accompanied by a make-whole payment, disrupts that schedule and threatens the trust's tax treatment. Defeasance sidesteps the problem: the loan is never prepaid at all, the collateral is swapped for government securities, and every bond payment continues exactly as scheduled.

Why It Matters for Your Loan

Yield maintenance can be the largest single line item in a refinance or sale, and its size is a market variable, not a fixed fee. A payoff contemplated after yields have dropped can carry a seven-figure penalty on a $10,000,000 loan, while the same payoff after yields rise costs the 1% floor. Commercial Lending Solutions calculates the actual make-whole under the note's discounting convention before recommending any early payoff, and structures new debt so the exit cost matches the client's real hold period.
