Finance and Tranche

In French, tranche means “slice.” Cutting deeper into the word’s etymology, we find the Old French word trenchier, meaning “to cut,” which has its likely origin in a Latin word meaning “to cut in three,” from Latin trini meaning “three each.” Tranche emerged in the English language in the late 19th century to refer to a division or portion of a larger pool or whole, and later developed a finance-specific meaning referring to an offering for sale of typically a set of bonds “cut” from a larger group of bonds, the tranche being differentiated by such factors as maturity or rate of return.
