Does a change in the market price of a loaned fungible item affect the obligation to return the like?

Primary text

A mere fluctuation in price, whether significantly (such as ten dinars becoming twenty dinars) or slightly, does not prevent the obligation to return the equivalent amount. This is because nothing has happened to the item itself; only the price has changed, making it analogous to wheat whose price fluctuates.
