revolving guarantee; basic guarantee
A legal/financial term for a guarantee that covers a continuing or fluctuating obligation, such as a line of credit, rather than a single fixed debt. Often contrasted with a standard guarantee (普通保証).
Banks sometimes require a revolving guarantee agreement when extending credit.
A revolving guarantee is used to secure obligations arising from ongoing transactions.
Compound of 根 (root, basis) and 保証 (guarantee), reflecting the idea of a fundamental or ongoing guarantee. The exact historical derivation is uncertain; the term is used in modern legal and financial contexts.
