Oil prices jumped to their highest levels in a year and a half on Monday after OPEC and non-OPEC producers agreed to cut oil output to ease a global glut, while the U.S. dollar extended gains before a Federal Reserve meeting this week, at which a rate hike is widely expected.

The agreement between OPEC and a number of other oil producing nations was the first joint action since 2001, following more than two years of low prices that strained many government’s budgets and spurred unrest in countries from the Middle East to Latin America.
