MORNING BID AMERICAS-Forever war?

Sept. 10 (Reuters) - Energy and bond markets are on edge once again after U.S. President Donald Trump said the Iran war would not end until after November's midterm elections. That came amid the most intense attacks on Gulf shipping in the conflict so far.

Meanwhile, markets await a likely European Central Bank interest rate rise and the first of the week's U.S. inflation updates on Thursday, as Treasury Secretary Scott Bessent's bond buyback salvo appeared to flop after details of the operation disappointed.

Crude oil closed at its highest level since late May above $100 per barrel on Wednesday, and 10-year Treasury yields hit their highest in three years, fast homing in on the 5% milestone.

U.S. producer price inflation data for August is up next on Thursday after the ECB policy decision, which is likely to be a quarter-point hike to 2.5%, just as European natural gas futures hit their highest in three years.
