Major US stock indexes have moderately decreased, affected by the fall of the commodity sector and the shares of large US creditors due to the situation in Turkey.

At the same time, Turkish President Recep Tayyip Erdogan, speaking in Ankara today, said that Turkey's fundamental macroeconomic indicators are strong and that his country is in economic and political siege, which, in his opinion, will continue.

The aggravation in relations between Turkey and the US began with the introduction of US sanctions against the two Turkish ministers (the Minister of Internal Affairs and the Minister of Justice), which was the result of Turkey's refusal to release the American pastor detained in Ankara. But this did not end there: at the end of last week, US President Donald Trump approved an increase in duties on aluminum and steel from Turkey to 20 and 50 percent, respectively.

Quotes of oil declined on Monday, as trade tensions and problems surrounding emerging markets worsened the prospects for demand for fuel, although US sanctions against Iran indicate a more stringent proposal in the future.

Most of the components of DOW finished trading in the red (24 out of 30). Leader of the growth were shares of Merck & Co., Inc. (MRK, + 1.10%). Outsider shares were DowDuPont Inc. (DWDP, -1.76%).

All S & P sectors recorded a decline. Most of all, the commodity sector fell (-1.3%).
