Negotiations between the United States and Iran have extended into a second day at the Bürgenstock venue in Switzerland, with both delegations remaining on site as discussions on the nuclear deal continue.
An American official confirmed that talks are ongoing, describing the exchanges as robust and covering all elements of the agreement.
The persistence of the talks suggests that neither side is prepared to walk away, even as the diplomatic process stretches into the early hours of Monday.
The continuation of high-level diplomacy keeps the focus on potential de-escalation in the region, a key variable for global energy markets.
While no breakthrough has been announced, the mere fact that talks are proceeding offers a counterweight to fears of renewed conflict.
Markets have been closely monitoring the situation, with shipping risk premiums in oil prices remaining sensitive to any developments from the Swiss venue.
