"Oil Shocks and the Economy"
Interested in trying to better-understand the under-discussed issue of the economic consequences of an Israeli attack on Iran I tried to see what exists in terms of research on the macroeconomic impact of oil price shocks.

Specifically, Global Insight (PDF) came up with this:
According to a 2007 estimate from Standard & Poor’s if Iran managed to close the Straights of Hormuz to shipping, oil might go to $250 a barrel which is much more than a $10 increase.
