OPEC member Kuwait earned 1.255 billion dinars ($4.65 billion) in November, its lowest monthly income this year due to the sharp decline in oil prices, the finance ministry said yesterday. The oil-rich emirate's revenues have been declining since peaking at $12.9 billion in August as the price of Kuwaiti oil, which makes up 95 percent of public income, dived to $35 a barrel from around $140 in July.
