At today's official launch of LafargeHolcim, CEO Eric Olsen was asked to comment on the group's position in Iran. It doesn't have one, but that won't necessarily always be the case given events in Austria this week.

On Tuesday 14 July 2015, Iran and the P5+1 countries (US, UK, France, China, Russia and Germany) agreed an historic deal to limit Iranian nuclear activity in return for a significant lifting of existing trade sanctions at a meeting in Vienna. The country's cement industry will be delighted by this agreement. The talks, in progress since 2006, could mark what has been termed a 'new chapter' in relations between Iran and the rest of the world by Iranian President Hassan Rouhani. For his part, US President Barack Obama stated that the deal would ensure that 'every pathway to a nuclear weapon is cut off' for Iran, but critics from the US, Iran, Israel and elsewhere, suggest that cutting all routes will not be possible. They are alarmed and have warned that the deal could lead to an arms race between Iran and Saudi Arabia, amid increasing animosity in the Middle East.

While the geopolitical implications of the deal are huge, the lifting of trade restrictions will greatly improve Iran's ability to deal internationally. This includes allowing increased oil exports. An article by Reuters anticipates that Iranian oil production could increase drastically from around 1 million barrels per day (mbpd) at present, possibly to its former peak of 3mbpd. (What this might do to the global oil price could be the subject of an entirely separate column). The easing of banking restrictions will make Iranian products more competitive and increase trade in many sectors.

Against this backdrop sits the Iranian cement industry, the world's third or fourth largest by production in 2014, depending on your source. It has an incredible 84.4Mt/yr of cement production capacity in a country of 77.5 million people. Assuming that it could produce and consume all of that cement at home, this would represent consumption of around 1100kg/capita/yr, far above the 600-800kg/capita/yr rate that is typical of a rapidly-developing economy.

Of course, Iran has not been consuming anything like this level of cement recently. According to figures released by its Employers Guild Association this week, Iran made 66.4Mt of cement in its 1393 calendar year, which ended on 21 March 2015. Assuming the above capacity, this gives Iran a cement utilisation capacity of around 78%.

Much of the cement made in Iran was exported in 2014 and so far in 2015. The country exported an incredible 18.4Mt/yr of cement and clinker in the year to 21 March 2015, up from 18.8Mt a year earlier. A large amount of this cement was available at low cost, to the extent that Iran has been accused (along with Pakistan) of dumping cement in the Middle East and East Africa. (Pakistani producers have even pointed out that Iranian cement is making inroads into the Afghan market, more traditionally a target for exports from Pakistan).

So what might happen to the cement trade dynamic in the region? Some suggest that the easing of sanctions can only increase the potential for Iranian cement imports in the region. Trade should become easier, facilitating exports.

Indeed, this is a factor, but it is only part of the equation. Instead, it is likely that, having earned foreign exchange via increased oil sales, Iran will be able to spend more at home. Reuters anticipates that demand for steel and cement will skyrocket as the country undertakes much-needed construction and infrastructure works. This situation would be similar to Saudi Arabia and other Gulf Cooperation Council (GCC) states. How Saudi Arabia reacts to this, both politically and in terms of cement trade, will be of high interest in the region and around the world.

Instead of increasing cement exports, the effect of the lifting of sanctions may decrease them. This will surely be welcome news to local producers currently being undercut in East Africa, as well as exporters in Pakistan, India and elsewhere. Could Pakistan even find itself exporting to Iran? If a US-Iran nuclear deal is possible, anything can happen...
