JGB futures jump more than half point as Nikkei slumps

TOKYO, April 14 (Reuters) - Japanese government bond futures jumped more than a half point on Monday as Tokyo's Nikkei share average fell sharply and prompted investors to shift money back into debt.

Gains in futures were also helped by gains in U.S. Treasuries late last week after a sharp deterioration in consumer confidence and disappointing earnings news from General Electric Co (GE.N).

June futures climbed 0.53 point to 139.84 2JGBv1 after jumping as high as 140.01.

The benchmark 10-year yield fell 4.5 basis points to 1.330 percent JP10YTN=JBTC. (Reporting by Satomi Noguchi)
