Iran's currency fell on Wednesday to an all-time low as former President Donald Trump was on the verge of clinching the U.S. presidency again, signaling new challenges ahead for Tehran as it remains locked in the wars raging in the Middle East.

The rial traded at 703,000 rials to the dollar, traders in Tehran said. The rate could still change throughout the day. Iran's Central Bank could flood the market with more hard currencies as an attempt to improve the rate, as it has done in the past.
