  • (written as Ceiling)
    The maximum interest rate that can be applied to a loan. The ceiling, or cap, is typically specified in the contact initiating the loan. This determines how much the financing cost of the loan amount can potentially change in response to changes in interest rates and other market conditions, and is an important consideration when executing foreign exchange investment strategies involving the borrowing of currency.

Origin & History of “ceiling”

Ceiling is something of a mystery word. It originally signified the internal lining of any part of a building, including walls as well as roof (the modern sense ‘overhead inside surface of a room’ began to crystallize out in the 16th century), and the material of which it was made took in wooden planks and even tapestry hangings, as well as plaster. But where it comes from is not at all clear. It has no apparent relations in other modern European languages, and the likeliest candidate as a source may be Latin caelāre ‘carve, engrave’. this is perhaps endorsed by an item in the accounts of the lord high Treasurer of Scotland, 1497, revealing how a ‘carver’ was paid £2 14s for ‘the ceiling of the chapel’ – an indication that the underlying notion of ceiling may be ‘carved internal surface of a room’.
