Gas Prices, Energy Supply, and Why a Few Dollars per Barrel Can Move the Whole Economy

Most of the recent coverage has centered around the geopolitical risks that could boost prices, even if the increase is “only” several dollars per barrel. That’s important from a macro standpoint because one of the first areas that gets reflected in the economy is the price of gasoline. If the price of oil increases, that’s effectively a tax increase for the end consumer, which means that their discretionary spending power is reduced.

The inflation aspect is what makes this particularly important for the markets. If the price of oil increases, that means that inflation could accelerate, which means that interest rates could remain high for longer than people expect. Even if core inflation is calm, the price of oil can have an impact on the service sector through distribution. The takeaway here is that an increase in the price of oil can have the effect of slowing down the economy, which is particularly concerning because that’s the type of environment that makes monetary policy particularly tricky.

  1. I like how you explained that even a small increase in oil prices can ripple through the entire economy by raising gas prices and reducing consumers’ discretionary spending. Do you think central banks like the Federal Reserve System would be more likely to keep interest rates higher if oil driven inflation continues to rise?

    1. Yes. if the inflation generated by high oil prices continue to push headline inflation higher and even worse, affect expectations and other prices like transport costs, the Fed will be compelled to keep interest rates high for much longer before considering cuts. If they are sure that it is purely temporary and core inflation remains under control, they can overlook it, but not without credibility concerns.

  2. It’s fascinating to see how fragile gas and energy prices can be. Gas prices were relatively low over the past couple of months, likely due to seasonal factors, but they have recently increased again. This shows how quickly prices can change based on market conditions and global events.

    However, oil prices affect more than just what we pay at the pump. They also impact households and businesses by influencing how much they can spend, invest, expand, and save. It does not just affect one economy; it affects the people and businesses involved in that economy, as well as anyone connected to the global oil market.

    1. Agreed. The pump price is only one of the more obvious routes through which oil passes, but it also affects shipping prices, airline prices, and other elements that become part of general inflation. This is how even minor oil changes can affect the behavior of consumers as well as interest rate expectations.
