Davlat pul birligi va boshqa davlatlarning pul birliklari o'rtasida almashinuv qilish, xuddi davlatning o'z tangalari o'rtasidagi almashinuv kabi, joiz hisoblanadi. Ikki pul birligi o'rtasidagi ayirboshlash kursi, agar bu pul birliklari bir-biridan farqli bo'lsa, turlicha bo'lishi mumkin. Biroq, bunday operatsiyalar qo'lma-qo'l tarzda amalga oshirilishi va kechiktirishsiz, to'g'ridan-to'g'ri almashinuv bo'lishi shart. Ayirboshlash kursi, ikki xil pul birligi o'rtasida bo'lgan taqdirda, hech qanday cheklovsiz o'zgarib turishi mumkin. Barcha fuqarolar davlat ichidan yoki tashqarisidan kerakli pul birligini sotib olishlari mumkin va buning uchun oldindan ruxsat olish yoki shunga o'xshash biror narsa talab qilinmaydi.

It is permissible to have exchange between the State currency and the currency of other states like the exchange between the State’s own coinages. It is permissible for the exchange rate between two currencies to differ provided the currencies are different from each other. However, such transactions must be undertaken in a hand-to-hand manner and constitute a direct transaction with no delay involved. The exchange rate can fluctuate without any restriction as long as it is between two different currencies. All citizens can buy whatever currency they require from within or outside the State, and they can purchase the required currency without obtaining prior permission or the like.
