Artikel 13

(1). Whenever the par value in the International Monetary Fund of the currency of a State participant is reduced in terms of the unit of account, or its foreign exchange value has, in the opinion of the Fund, depreciated to a significant extent within that participant’s territory, that participant shall pay to the Fund within a reasonable time an amount of its currency required to maintain the value, as of the time of subscription, of the amount of such currency paid in to the Fund by that participant pursuant to Article 6 and pursuant to the provisions of the present paragraph, whether or not such currency is held in the form of notes, letters of credit or other obligations accepted pursuant to Article 9, provided that the foregoing shall apply only so long as and to the extent that such currency shall not have been initially disbursed or exchanged for another currency.
(2). Whenever the par value of the currency of a State participant is increased in terms of the unit of account or its foreign exchange value has, in the opinion of the Fund, appreciated to a significant extent within that participant’s territory, the Fund shall return to that participant within a reasonable time an amount of such currency equal to the increase in the value of the amount of such currency to which the provisions of paragraph (1) are applicable.
(3). The Fund may waive or declare inoperative the provisions of this Article when a uniform change in the par value of the currencies of all State participants is made by the International Monetary Fund.
