(32)In order to ensure full transparency, the consumer should be provided with information concerning the borrowing rate, both at a pre-contractual stage and when the credit agreement is concluded. During the contractual relationship, the consumer should further be informed of changes to the variable borrowing rate and changes to the payments caused thereby. This is without prejudice to provisions of national law not related to consumer information which lay down conditions for, or prescribe the consequences of, changes, other than changes concerning payments, in borrowing rates and other economic conditions governing the credit, for instance rules providing that the creditor may change the borrowing rate only where there is a valid reason for such change or that the consumer may terminate the contract should there be a change in the borrowing rate or in some other economic condition concerning the credit.
