Households in the U.S. Northeast are expected to see a sharp increase in heating costs this winter, while the national average bill is projected to reach $1030, up about 9% from a year earlier. Heating oil is forecast to post the biggest increase, with costs per household nearing $2300, up 31%. Electricity-heated homes are also expected to pay about 9% more. The rise is largely attributed to Brent crude climbing from $72 to above $100 amid the U.S.-Iran conflict and restricted shipping through the Strait of Hormuz.
