Aug 18 (Reuters) – European shares edged lower on Tuesday as crude prices rose after hopes for a lasting ​U.S.-Iran peace deal faded, while surging ‌euro zone bond yields added to pressure on equities amid worries about persistent inflation.

The pan-European STOXX 600 was down 0.2% at 654.81, as ‌of ​0703 GMT.

Iran will shift ⁠to a “fully offensive” ⁠military posture because efforts to negotiate a permanent end to the war with the U.S. have stalled, a senior Iranian ​official told Reuters on Monday, as Washington ruled out extending a temporary ⁠ceasefire agreement.

Energy shares rose ⁠the most, up 0.6% as ​Brent crude climbed around 0.6% to $91.41 a ​barrel. [O/R]

On the flip side, basic resources fell ‌the most, down 1%,  tracking lower gold prices as rising Treasury yields dampened demand for the bullion metal ahead ⁠of the release of minutes from the U.S. Federal Reserve’s July policy meeting. [GOL/]

Euro zone long-dated bond ⁠yields ‌hit multi-year highs on fears ⁠that a prolonged Middle East conflict ​could ‌fuel inflation via higher energy ​prices and ⁠increase defence borrowing. Germany’s 10-year Bund yield reached its highest since 2011, while France’s 10-year yield hit a 16-year peak.
