Ahmadinejad says at a news conference in New York that he opposed the decision by Iran's central bank to allow the currency, the rial, to drop by about 60% against the dollar in the first 9 months of 2012. The central bank policy is to maintain foreign exchange reserves in the face of stricter international sanctions against Iran's nuclear weapons development program. Ahmadinejad delivered his final address to the UN General Assembly at the end of his second four year term, his last because of Iran's term limits.
