As the U.S. government attempts to combat high gas prices by drawing on its oil reserves, investors should pay attention to the impacts on the U.S. economy and consumer behavior.----- Transcript -----Welcome to Thoughts on the Market. I'm Michael Zezas, Head of Public Policy Research and Municipal Strategy for Morgan Stanley. Along with my colleagues bringing you a variety of perspectives, I'll be talking about the intersection between U.S. public policy and financial markets. It's Wednesday, April 6th at 10 a.m. in New York.Last week President Biden announced the largest release of oil reserves in history, about 1 million barrels per day for the next 6 months from the government's Strategic Petroleum Reserve. The move is intended to put downward pressure on the price of gasoline by increasing the supply of oil, thereby relieving pressure on the American consumer from higher costs at the pump. Will it work? That remains to be seen, but investors should pay close attention, not just because it impacts their cost of driving, but also because it impacts the outlook for the U.S. economy by affecting how consumers behave.Our U.S. economics team, led by Ellen Zentner, has done some work worth highlighting here. The big takeaway is this; oil price shocks do dampen consumer activity, but not right away. The jump in oil prices seems to have to sustain itself before having a big impact. For example, consumption in real dollar terms seems to weaken after initial oil price increases, but it's not until 2 to 3 months after that shock that consumers start to buy less of other things in order to have enough money to pay the higher costs of filling up their cars. Looking at this effect on a specific product, for instance automobiles, you can see a similar pattern. Spending on cars doesn't seem to change in the first month after a price shock but drops almost 10% thereafter for 8 months.So the bottom line is this; the White House's move on releasing oil reserves has some time to play out. But if it doesn't reduce gas prices in the next couple months, then it becomes one cost pressure among several, including labor costs, that could start slowing the U.S. economy from its currently healthy pace. It's one reason our equity strategy team continues to see higher costs creating some pressure in key sectors of the stock market, notably consumer services, apparel and staples.Thanks for listening.
