The Swiss Market Index started the week in the red, tumbling 1.75% on Monday's close, as reports of a new source of tensions between the US and Iran overshadowed the releases of the country's gross domestic product and retail sales.
Iranian negotiators will suspend talks and the exchange of documents with their US counterparts in protest of Israeli aggression in Lebanon, Bloomberg News reported, citing a statement carried by the semi-official Tasnim news agency. The suspension follows a fresh exchange of fire between Tehran and Washington over the weekend, even as the two sides had been indirectly negotiating terms of a draft deal that would extend their ceasefire agreement by 60 days.
Back home and in economic news, Switzerland's final gross domestic product, adjusted for sporting events, rose 0.4% in the first quarter, compared with the flash estimate of a 0.5% increase and the prior quarter's 0.2% rise. The State Secretariat for Economic Affairs attributed the growth to the industrial sector.
Meanwhile, Swiss retail sales inched up 0.1% month over month in April, following a revised 0.3% gain in March, data from the Federal Statistical Office showed. In other economic news, the procure.ch-UBS manufacturing PMI climbed to 57.3 in May from 54.5 in April, surpassing the consensus estimate of 54.
