Asian stocks edged up on Friday as Wall Street benefited from buoyant crude oil prices and expectations US borrowing costs will remain at stimulatory levels at least until year-end.

Japan’s Nikkei added 0.5 percent and South Korea’s Kospi tacked on 0.2 percent.

MSCI’s broadest index of Asia-Pacific shares outside Japan stood steady. The index was on track to rise 0.25 percent on the week, during which it reached a 1-year high.
