Can the new intelligence assessment that Iran gave up the effort to make nuclear weapons three years ago affect oil prices and to what extent?

This should take some of the pressure off oil prices and any its significant in another way, that any developments in the middle east would be taken in a different light, not as a part of a cloud of uncertainty but taken by evaluating the new development on its own merits carefully. Interestingly this happened in the same week that another development ocurred. The President of Venezuela lost a referendum in Venezuela designed to givie him emergency powers by amending the constitution. Even by controlling most of the media and using oil money to support social programs and giveaways to the poor and working classes, Chavez lost the referendum that he initiated. It was not clear what would happen in Venezuela, and the Iran development was a surprise, so this also means that in international affairs educated people will look at a lot of different possibilities from now on before drawing any conclusions. In fact this is exactly what appears to have happened in the case of the intelligence on Iran, as mentioned here the new assessment was based on allowing different agencies and groups within the government to come up with different conclusions and then to test the facts again and again, and to question old assumptions....
