Iran Risks Will Curb Investor Enthusiasm Even as Sanctions Ease

The end of economic sanctions on Iran under this week’s nuclear deal has been portrayed as a gold-rush opportunity in an oil-rich Gulf state, but returning to business as usual won’t be as easy as the burst of enthusiasm suggests.

Investors who wait months for sanctions to be lifted will then have to gamble that they won’t run afoul of enduring blacklists or the vow by the U.S. and other world powers that sanctions will “snap back” into place if Iran fails to live up to commitments to restrict its nuclear program.
