Newswise — On Monday, oil prices dropped to $31 a barrel—the lowest in almost 12 years—and the news caused a major selloff after investors got nervous that prices could dip even lower in the near future. This is mostly thanks to too much supply and too little demand. It also doesn't help that Iran could start exporting oil again as part of last year's nuclear deal. Matt Murray, director of the University of Tennessee, Knoxville, Howard H. Baker Jr. Center for Public Policy is available for comment. Murray says gas prices are a key element of the economic outlook for the state and nation. View Murray’s profile at www.experts.tntoday.utk.edu/experts/matthew-murray/.
