What the insurer is actually doing. The loan is secured by the policy alone, and the maximum is set by the policy's value rather than by anything about the borrower. Under RCW 48.23.080(1)(b), for policies issued after the operative date of the state's valuation provisions, the sum advanced, including interest to the end of the current policy year, may not exceed the cash surrender value at the end of that year. The insurer may also deduct any existing indebtedness and any unpaid balance of the current year's premium from the loan value. And under RCW 48.23.080(4) the insurer may reserve the right to defer making the loan for up to six months, with one exception that says a great deal about the purpose of the provision: it may not defer a loan made to pay premiums. The mechanism exists to keep policies in force.
The consequences of "no schedule" run in both directions. Nothing requires repayment, and that is genuinely different from any other borrowing a household can do. But RCW 48.23.080(3) permits the contract to provide that interest not paid when due "shall be added to the existing indebtedness and shall bear interest at the same rate", which is compounding against a slowly growing account. The same subsection sets the end point: when the total indebtedness, including interest due or accruing, equals or exceeds the loan value that would otherwise exist, the policy terminates in full settlement of the debt and becomes void. The consumer protection sits in the next clause, and it is the single most useful thing to know here: no such termination is effective before at least 30 days after the insurer has mailed notice of the pending termination to the insured and to any assignee. A letter that looks like routine administration is, at that point, the last warning.
The price is regulated, and the two shapes are worth telling apart. RCW 48.23.085(2) requires a policy issued on or after August 1, 1981 to contain either a provision permitting a maximum interest rate of not more than eight percent per annum, or a provision permitting an adjustable maximum rate. Where the rate is adjustable, subsection (3) caps it at the higher of two figures: the "published monthly average", defined in subsection (1) as Moody's Corporate Bond Yield Average, Monthly Average Corporates, for the calendar month ending two months before the rate is determined; or the rate used to compute the policy's cash surrender values, plus one percent per annum. Subsection (5) requires the maximum to be redetermined at least once every twelve months and no more often than once in any three-month period, and permits an increase only where the computed change is at least half a percentage point, while requiring a reduction on the same half-point test. Subsection (6) obliges the insurer to tell the policyholder the initial rate and to give reasonable advance notice of any increase. So a fixed-rate loan is priced by the contract and an adjustable one is priced by a bond index the insurer does not control, and which of the two a policy uses is printed in the policy.
A participating policy adds one more variable. Where the contract pays dividends, the dividend on the borrowed portion of the value may be calculated differently from the dividend on the rest, a difference the market calls direct recognition. It is a matter of the insurer's dividend practice and the contract's own dividend provision rather than of statute, which is why the policy and the insurer's current dividend scale, not a general rule, are what answer it for a given contract.
One fact about how this is sold belongs on the page. The idea of borrowing against a policy is a central selling point for cash-value coverage, and the illustrations that carry it depend on assumptions about two future numbers the buyer does not control: the loan interest rate and the rate credited to the policy. Where the credited rate is assumed to run above the loan rate, the illustration shows borrowing that costs nothing on net; where it does not, the same policy drains. The assumption is stated in the illustration's own columns, and the guaranteed columns are the ones that hold if the assumption fails.
