Pump Prices Cheaper on the Week for South Dakota and the

Majority of the Country

February 12, 2018 - At $2.58, the national gas price average has decreased for the first time week-over-week this year. Today’s price is 3 cent less than last week, 6 cents more than a month ago and 30 cents more than a year ago. Motorists can find gas for $2.50 or less at 53 percent of gas stations across the country.

“Gas price averages are less expensive for 78 percent of states, including South Dakota, as compared to last Monday. Motorist filling up in the Midwest, South and East Coast are most likely to see the positive change at the pump,” said Marilyn Buskohl, AAA spokesperson. “Unfortunately, it’s too early to know if this one-week decline is the start of a cheaper gas price trend.”

South Dakota Average Gas Prices:

  • Current Avg. $2.556
  • Week Ago Avg.$2.575
  • Month Ago Avg. $2.477
  • Year Ago Ave.$2.335

Quick Stats

  • The largest weekly changes in the nation’s top ten markets are: Indiana (-14 cents), Michigan (-11 cents), Kentucky (-9 cents), Ohio (-8 cents), Illinois (-6 cents), Utah (+6 cents), Hawaii (+5 cents), Missouri (-4 cents), Maryland (-4 cents) and Florida (+4 cents).
  • The nation’s top ten most expensive markets are: Hawaii ($3.44), California ($3.35), Alaska ($3.04), Washington ($3.00), Oregon ($2.89), Pennsylvania ($2.86), Nevada ($2.78), Washington, D.C. ($2.77), New York ($2.76) and Connecticut ($2.74).

Central and Great Lakes Region

Gas prices are less expensive on the week across the Great Lakes and Central region, except North Dakota where prices remained stable. Indiana (-14 cents), Michigan (-11 cents), Kentucky (-9 cents), Ohio (-8 cents) and Illinois (-6 cents) saw not only the largest decreases in the region, but in country. In the region, North Dakota ($2.63) and Iowa ($2.60) are selling the most expensive gasoline. At $2.37, Ohio is selling the cheapest gas in the region and the 7th cheapest in the country.

Compared to one month ago, Michigan (-16 cents), Ohio (-13 cents), Illinois (-12 cents), Indiana (-11 cents) and Kentucky (-5 cents) are five of only six states in the country that are paying less at the pump. These states have seen very volatile gas prices since January. 

Oil market dynamics

At the close of Friday’s formal trading session on the NYMEX, WTI dropped by nearly $2 to settle at $59.20. Price gains made throughout January, which saw a closing high of $66.27, were wiped away after trading last week. Last week’s losses, which were buoyed by a strengthening dollar, may continue into this week after EIA’s latest weekly petroleum report revealed that U.S. crude production hit 10.25 million b/d – a new record weekly production rate.

The continuing growth in U.S. crude oil production may give the market some pause as it continues to assess the long-term impact of OPEC’s production reduction agreement, which remains in effect through the end of 2018.
