TOKYO, April 30 (Reuters) - Benchmark Japanese

government bond (JGB) yields rose to a 29-year high on Thursday

after the Federal Reserve signalled growing concerns about

inflation, while a stalemate in U.S.-Iran peace talks pushed oil

prices higher.

The benchmark 10-year JGB yield rose 4 basis

points (bps) to 2.500%, the highest since June 1997. The

five-year yield rose 3 bps to 1.885%. Yields move

inversely to bond prices.

Although the Fed kept interest rates steady, three policymakers

dissented from the central bank's statement, reflecting a

deepening split over whether it should continue signalling a

bias toward lower borrowing costs. U.S. Treasury yields rose to

a one-month high after the release of the policy statement.

Oil prices surged over 6% on Wednesday to settle at their

highest in weeks, with deadlocked U.S.-Iran negotiations making

investors more concerned about a prolonged disruption to Middle

Eastern energy supplies.
