Why do Gas Prices Rise Quickly, but Fall Slowly?

Summary: Gas Prices 101

Ben Carlson has been talking about the dislocation between crude oil prices and gas prices for years. I think that he summed it up perfectly in this tweet:

Why do Gas Prices Rise Quickly, but Fall Slowly?

It does feel like prices at the pump rise whenever crude oil is climbing but are much slower to fall when crude prices are retreating. Oil prices jumped about 40% when Russia invaded Ukraine to a high of over $130 a barrel. Gas prices quickly followed suit: in Winnipeg, Manitoba, gas rose from $1.49 to $1.73/litre between February 21 and March 9. They’ve stayed at that elevated level despite oil falling to $94.79 per barrel as of March 15.

There is supposed to be an intrinsic tie between oil and gasoline. Even President Biden can’t wrap his head around the disconnect:

Why do Gas Prices Rise Quickly, but Fall Slowly?

Why don’t gas prices move with oil prices in both directions?

Rockets and Feathers

The way in which gas prices move with crude prices has a name in the industry: rockets and feathers. When oil prices rise, gas shoots up like a rocket. When oil prices fall, gas drops like a feather.

This pricing practice is enabled by a phenomenon that’s fairly unique to gasoline: advertising prices on big signs along roadways. It’s an example of radical transparency that has been destructive for consumers. What’s the point of boldly advertising your price if everyone else charges the same amount? With the exception of some rebates offered at the pump, gas stations effectively do not compete based on price. Further, the product itself is a commodity that has to meet minimum quality standards to be sold for use in vehicles, and the “experience” provided by different gas stations is roughly the same. These are therefore businesses that aren’t competing on price, product, or consumer experience. This is a perfect recipe for cartel-like behaviour that ends up costing the end consumer. While price fixing is extremely difficult to prove indisputably, it clearly plays a role in this instance. The stations aren’t really signalling price to consumers, but rather to each other. Stations will raise prices immediately to reflect increased input costs, but they are hesitant to lower prices as there is no competitive pressure to do so until other stations do.

Economics 101

Gas is a commodity that represents a high degree of price inelasticity, meaning that people don’t tend to cut their consumption very much as prices rise. This doesn’t apply for products and services that are price elastic. If the price of carrots rises too high, for example, then I’ll start buying broccoli instead. We don’t see this with gas; there’s nothing else I can put in my car to make it go if I don’t want to pay for gasoline. Of course, this can eventually reach a tipping point. As petroleum products get more expensive, then alternative energy sources become more attractive not just from an emissions perspective, but also economically. One could argue that reduced gas use would be a silver lining to higher prices. However, pivoting a global economy that runs on oil and gas to renewables is a drawn-out process. In the short term, there is little economic pressure to induce price cuts for gas.

An old adage in economics states that the cure for high prices is high prices. Even a price inelastic good like gasoline will get to a point where households simply must reduce consumption due to budgetary constraints. Oil futures briefly went negative in April of 2020 when demand dried up because people were confined to their homes; falling prices resulted from reduced demand. You want gas prices to fall? Then drive less and lower the demand.

Tips to Ensure the Effective Use of Your RRSP

For a lot of Canadians, this is the only time of year that much thought is given to RRSPs. RRSPs have traditionally been the primary means of saving for retirement in a tax-advantaged way. Despite this, operational complexity of RRSPs prevents many from taking maximum advantage of these accounts. As more and more pension plans shift from defined benefit to defined contribution, effective use of RRSPs will be crucial for fulfilling retirement goals...

Is Retirement Still the Goal?

Another revelation that has come to light in recent years for more and more people is that the traditional concept of retirement is inherently flawed. The idea that you work your whole life, while building assets in hopes that when you are older you will be able to enjoy those assets. The problem of course is that you spend the majority of your life not doing the things that make you happy, and instead you wait until you are too old to do the things you want to do and the sad truth is that far too many people pass away in the first few years of their retirement and never get to enjoy what they built as a result of their hard work.
