LONDON, July 30 (Reuters) - Euro zone bond yields rose on

Thursday as traders reacted to a jump in U.S. market rates after

Wednesday's Federal Reserve decision and a rise in oil prices,

driven by a widening of the U.S.-Iran conflict.

Longer-dated bond yields - which typically reflect concerns

about inflation and growth - rose the most after the 30-year

U.S. Treasury yield climbed to a 19-year high

overnight following the Fed's decision to hold interest rates.

Analysts said the rise in long bond yields showed traders

are sceptical about the Fed's commitment to reducing price

pressures, as new chair Kevin Warsh again refused to offer any

clues about future moves.

Germany's 30-year bond yield rose 3 basis points

(bps) on Thursday to 3.664%, although the moves in Europe were

more muted than those in the U.S., reflecting expectations that

the European Central Bank will raise rates again this year to

tame inflation.

A rise in oil prices was also adding to the upward pressure

on bond yields as traders factored in the possibility of

stronger inflation. Brent crude was up 2% at $92.90 a

barrel.

Germany's 10-year bond yield - the benchmark for

the euro zone - climbed 1 bp to 3.17%. Yields move inversely to

prices.

Energy prices climbed as the U.S. and Iran continued to

trade attacks and the conflict spread in scope, with a drone

hitting a U.S.-owned gas storage tanker at Egypt's Mediterranean

port of Damietta according to British maritime security firm

Ambrey.

Shorter-dated European bond yields slipped, however, causing

yield curves to steepen. That reflected a fall in two-year U.S.

Treasury yields overnight as traders reduced their

bets on immediate Fed rate hikes.

The size and importance of the U.S. economy and its markets

mean European yields broadly follow moves in Treasuries.

"Markets have little time to catch their breath as the data

calendar is packed on both sides of the Atlantic, and the Bank

of England will announce its interest rate decision," said Erik

Liem, rates strategist at Commerzbank.

Euro zone GDP data is set to be released, and the Bank of

England, which is expected to hold rates, is due to announce its

decision at 1100 GMT (1300 CEST).

U.S. personal consumption expenditures inflation data is due

later in the day.
