Brent crude futures for January delivery settled down $1.08, or 1.17 percent, at $91.49 a barrel on Tuesday, Nov. 10, Reuters reported. U.S. West Texas Intermediate futures for December fell 81 cents, or 0.93 percent, to $86.04.

Both were the lowest settlements since Aug. 31, and the second straight day of declines, according to Reuters. Oil was down at least 10 percent so far in November, Reuters reported.

The intraday low

Brent fell below $90 a barrel during Tuesday's session for the first time since August, touching an intraday low of $89.16, CNBC reported. Early in the session prices were down more than $3, Reuters reported.

Prices recovered part of that loss after Mohsen Rezaei, Iran's top security official, said in an interview with Al-Mayadeen that no negotiations were under way between Tehran and Washington, according to Reuters. U.S. officials played down the need for further military action against Iran, Reuters reported.

Gas and products

December natural gas rose 2.42 percent to $3.296 per million British thermal units, the only energy contract to settle higher, according to exchange settlements cited by The Edge. RBOB gasoline futures fell 1.59 percent to $2.6088 a gallon. Ultra-low-sulfur diesel futures fell 1.99 percent to $4.1309 a gallon.

At the pump, regular gasoline averaged $3.98 a gallon, according to AAA, about 39 cents less than a month earlier, NPR reported on Nov. 10.

In the price index

In the October consumer price index, released on Tuesday, gasoline prices rose 1.0 percent in October after a 9.1 percent increase in September, CNBC reported. Diesel rose 2.7 percent after 11.9 percent, Reuters reported. The overall energy index rose 0.7 percent. The natural gas index fell 0.8 percent.

Gold

Gold fell 2.6 percent on Tuesday as the dollar rose 0.5 percent, Reuters reported. Spot gold was up 0.4 percent at $4,049 an ounce on Wednesday morning, according to Reuters. That is a morning price, not a settlement.
