with the lifting of sanctions will come a new influx of foreign money. already plenty of european companies have been sending folks over to talk, strike deals, etc. the chinese have been doing so with total disregard for sanctions, effectively leveraging the situation to their advantage by hiring only chinese workers and, in response to protests, saying take it or leave it.
this will have one negative impact, however, and that will be the current (and completely unislamic, i think) incentive to keep money in the bank for folks -- they were offering ~ 18% interest per month
on accounts. i girl in vancouver took student loans to pay for her schooling, put the total loan amount in a savings, used the interest revenues to pay her tuition each semester, then handed back a wad of cash to pay off her loans and had plenty left over. unfortunately this doesn't always guarantee accessible return on investment as sometimes the government freezes all accounts to prevent moving their funds off shore. (this doesn't apply if you're an affiliate of the government as then you can do whatever you please with great impunity)
