0626 GMT - U.S. Treasury yields open higher in European trade after a pause in trading in Asian hours as the Tokyo market is closed. The driver is an increase in oil prices, even as investors look out for some diplomatic progress between the U.S. and Iran with the possibility of a meeting between the presidents of both countries at the UN meeting. Regarding a Trump-Xi summit, "for markets, the big question is what's going to happen when the current one-year trade truce expires in November, and whilst the general tone remains positive, there still isn't an agreement yet," Deutsche Bank strategists say in a note. The 10-year Treasury yield rises 1.9 bps to 4.981%, according to Tradeweb.
