Iran's currency fell to an all-time low as former president Donald Trump apparently clinched the US presidency again, signaling new challenges for Tehran. The rial traded at 703,000 to the dollar, and Iran's Central Bank may flood the market with more hard currencies to improve the rate. The slide comes as the rial already faces considerable woes over its sharp slide in value, and some Iranians fear that Trump will intensify sanctions, worsening the economy and social situation.
