Legal Definitions - usura maritima

Usura Maritima is a historical legal term referring to the specific type of interest charged on loans related to maritime voyages, known as bottomry or respondentia bonds.

Unlike conventional loans, the interest rate for usura maritima was permitted to be exceptionally high because it directly reflected the significant risks inherent in sea travel. If the ship or its cargo, which served as collateral for the loan, was lost at sea (due to storms, piracy, or other perils), the lender would lose their entire investment. Consequently, these high interest rates were generally exempt from standard usury laws, which typically cap interest rates to prevent excessive charges.

• Example 1: Financing a Risky Expedition

  A shipping magnate in the 18th century needed funds to outfit a vessel for a perilous journey across uncharted waters, known for treacherous weather and potential encounters with privateers. To secure the necessary capital, the magnate took out a loan, pledging the ship itself as collateral. The lender, recognizing the substantial risk that the ship might never return, charged an interest rate far exceeding typical land-based loans of the time. This elevated interest, reflecting the "no ship, no repayment" condition, was considered usura maritima and was legally permissible despite its high value.

• Example 2: Protecting Investment in Valuable Cargo

  A merchant sought to transport a valuable consignment of spices and silks from the East Indies to Europe. Given the long voyage, the possibility of shipwreck, or the cargo being plundered, the merchant secured a loan using the cargo as collateral to cover the costs of the expedition. The financier provided the funds but demanded a high interest rate, understanding that if the cargo was lost at sea, the loan would not need to be repaid. This interest, specifically tied to the safe arrival of the cargo and reflecting the inherent dangers of maritime transport, falls under the definition of usura maritima.
