JGB sell-off deepens, futures hit 9-month low

TOKYO, May 23 (Reuters) - Japanese government bonds fell sharply on Friday and futures stuck a nine-month low as more investors kept bailing out of the market by dumping debt, trying to limit damage to their portfolios.

Traders have said heavy selling by big Japanese banks and other domestic players has been driving the renewed market sell-off over the past week. Thursday's tumble in U.S. Treasuries added more fuel to the drop.

June 10-year futures 2JGBv1 were down 1.16 points at 134.27 after hitting a nine-month low of 133.98. The benchmark 10-year yield JP10YTN=JBTC shot up as much as 10 basis points to 1.755 percent, a nine-month peak. (Reporting by Eric Burroughs; Editing by Hugh Lawson)
