According to swissinfo.ch, during the first seven months of 2017, exports to Iran grew by 24.7 percent to $256.2 million, compared to the figure for the same period a year ago. This follows a trade agreement external link between the two countries that came into force in mid-March; it had been frozen since 2005.
"The positive trend for the export of goods — apart from precious metals — continued this year," Fabian Maienfisch, spokesman for the State Secretariat for Economic Affairs told the fourth Europe-Iran Forum, which is being held over two days in Zurich.
Last year total exports (excluding precious metals) to Iran grew by 11.1 percent.
In January 2016, Switzerland lifted some of its economic sanctions against Iran in keeping with the United Nations and European Union.
The new agreement aims to strengthen the protection of intellectual property and to improve the legal framework for economic trade. It should also reduce potential discrimination of Swiss businesses. The creation of a joint economic commission is also planned.
Despite improved export conditions, money transfers to and from Iran remain a major obstacle. Swiss banks are still loathe to risk potentially massive fines by engaging with Iran.
"As the United States still maintains numerous sanctions, financial institutions still do not feel comfortable enough to get involved in transactions with Iran again," explained UBS spokesman Fabio Sonderer.
Credit Suisse echoed this position. "Although the international community has lifted some of the sanctions against Iran, other sanctions that affect our international activities remain in place," said spokesman Tobias Plangg.
The Zurich Cantonal Bank (ZKB) believes talk of a business recovery is premature, said the banks' Marilena Baiatu.
SECO acknowledges that the banks' current stance makes it difficult for Swiss companies to establish business relations with Iran.
To better understand the sanctions still in force and thus improve legal security, SECO has organized several information meetings, to which the US Office of Foreign Assets Control (OFAC) was also invited. However, OFAC's position regarding Swiss banks is unclear. Maienfisch said OFAC simply "took note of the Swiss objections".
US President Donald Trump is considering whether to withdraw from the 2015 nuclear deal on curbing Iran's nuclear program, reached between Iran and six major powers.
If Trump does not recertify on October 15 that Iran is in compliance with the agreement, the American Congress would have 60 days to decide whether to re-impose sanctions on Tehran suspended under the accord.
Ambassadors to the United States from Britain, France, Germany and the European Union have all strongly backed the nuclear agreement with Iran as long as Tehran continues to comply with the pact.
