Brent crude is poised to fall by three percent this week, its steepest decline noted since December, amid concerns of global economic problems and supply disruption fears.

Brent increased five cents to $116.13 a barrel, whereas US crude rose three cents to $102.57 a barrel, which is expected to fall by two percent in its biggest weekly decline in a month, reported Reuters.

Investors are awaiting the results of US non-farm payrolls data, while a survey reported that businesses outside the farm sector added 170,000 jobs in April.
