Markets are extending gains from last week; all four major indices were up (S&P +0.7%, Nasdaq +2%, Russell +3.8%). The S&P 500 is opening just over 1% below all-time highs, raising the question of how much of the Iran deal was already priced in. Without the deal, a 5-10% pullback might have been expected given closed Straits of Hormuz and rising energy prices.
The fact that markets didn't fall more suggests the positive outcome was anticipated. This makes Kevin Warsh's job as Fed chair easier with crude oil falling below $80/bbl (first time since April 17). Overseas markets, which rely more on the Straits of Hormuz, are bouncing back strongly.
