"Iran's currency plummeted to an all-time low on Saturday, registering a more than 21-percent drop in a span of two weeks against the US dollar, currency tracking websites and money changers said.
The rial was traded at between 39,000 and 40,000 per dollar on the open market on Saturday, down from about 33,000 two weeks ago, according to money changers contacted by AFP."
Will the decline in the value of the rial make Iran any more flexible in its negotiations with the P5+1 over its nuclear weapons development program? Probably not. On the other hand, it certainly means that Tehran has that much less to distribute to its terrorist proxies, e.g., Hezbollah.
