There are no compelling internal reasons for the US economy to tank. A stock market correction in the 10-20% range to test support levels is reasonably likely. The EU getting yanked out of the Iran deal is a major reason for concern. This is a threat to both the economy and the market of the US. China is having a big deleveraging push at the moment but that will be helped by China taking over all of the deals the EU have had to give up in Iran. However that may not be enough help to avoid some of a downturn. My question is how likely is the interaction of Chinese and EU problems to cause major US problems in both the market and the economy?
