Certain commodities, such as houses, ships, machines, etc., can be loaned out only as fixed capital by the nature of their use-values. Yet all loaned capital, whatever its form, and no matter how the nature of its use-value may modify its return, is always only a specific form of money-capital.

Context

“Money may be loaned out in either form. It may be loaned as fixed capital, for instance, if it is paid back in the form of an annuity, whereby a portion of the capital flows back together with the interest. Certain commodities, such as houses, ships, machines, etc., can be loaned out only as fixed capital by the nature of their use-values. Yet all loaned capital, whatever its form, and no matter how the nature of its use-value may modify its return, is always only a specific form of money-capital. Because what is loaned out is always a definite sum of money, and it is this sum on which interest is calculated. Should whatever is loaned out be neither money nor circulating capital, it is also paid back in the way fixed capital returns.” source
