TOKYO, May 23 (Reuters) - Japanese government bond prices edged higher on Thursday as risk aversion in the broader markets due to persistent U.S.-China trade fears and Brexit concerns increased investor demand for safe-haven debt.
The five-year JP5YTN=JBTC and 10-year JP10YTN=JBTC JGB yields each declined 0.5 basis point to minus 0.170% and minus 0.060%, respectively.
The 30-year yield JP30YTN=JBTC also fell half a basis point, to 0.515%.
Reports that the United States could impose restrictions on Chinese technology company Hikvision renewed market jitters about trade on Wednesday, reversing a relief rally that followed Washington's move to temporary ease curbs against Huawei Technology Co Ltd HWT.UL.
A deepening Brexit crisis also sapped investor risk appetite. Pressure on British Prime Minister Theresa May to resign increased after her new Brexit gambit backfired and as a key ally resigned from her cabinet.
Equities sagged broadly, with Japan's Nikkei .N225 slipping 0.7%.
