this is business briefing. i'm sally bundock. a crude reality for iran: president trump plans to reinstate economic sanctions following his decision to withdraw from the international nuclear deal. a country in crisis: argentina looks to mend its broken relationship with the imf as the country attempts to settle investors' nerves. and on the financial markets, traders around the world are grappling with a decision by donald trump. the picture is emerging in asia. the price of oil is on the move, and safe havens are in focus. so in business today, we are leading with the decision on the part of donald trump to withdraw from the iran will —— nuclear deal. regional

trade restrictions crippled around's oil industry. —— iran's. but experts estimate that new sanctions will only affect 200 thousand barrels per day worth of iranian supply — that's less than 1% of global output. the decision is likely to compromise iran's business relations with the west. following the lifting of sanctions in 2016, the us plane manufacturer boeing struck a deal with iran's national carrierfor 80 aircraft, worth around $17 billion. the move has also frustrated america's european allies who have voiced their support for the nuclear deal. since the removal of sanctions, european trade with iran has more than tripled to almost $25 billion last year. with me is dr lindsay newman, north america political risk analyst at ihs markit. it is your take on this decision and

why donald trump decided to withdrawal. sure. by now we know that he chose to withdrawal from the agreement. in a related memorandum, it is said that the administration's plan was to withdraw from the related sectors. the headline coming here, though, is how closely donald trump is sticking to the domestic policy that he and his team have set up policy that he and his team have set up to themselves. worse than taxes, the rollback on barack obama's orders, pulling out of the paris climate accord, and we are initiating the negotiations of nafta. so this is a campaign promise that will keep the use domestic audience. . two in the view of iran,

what is the political risk? the question is how they will react to this. they have a few options. and we anticipate is to happen is that they will show some restraint. matt whitley has shown us in response to donald trump make an yesterday. they can also listen the dispute resolution programme while trying to pursue the programme and he would negotiations can come out with europeans. they could withdraw from thejcp are all from the nuclear proliferation treaty. but initial thing is to see what iran can get from continuing to participate in negotiations under the jcpoa. from continuing to participate in negotiations under the jcpoa. -- michael o'connell. just remind negotiations under the jcpoa. -- michael o'connell. just remind us what the jcpoa ills. michael o'connell. just remind us what thejcpoa ills. ——jcpoa. —— just remind us what thejcpoa means. it is the acronym to the agreement.

this is the agreement between the uk, ryan, united states, germany, and france. —— uk, iran, united states. the economy was kept hampered on many levels by sanctions. it is interesting to me the expert they spoke to earlier in the expert they spoke to earlier in the programme was talking about the fa ct the programme was talking about the fact that for the people of iran, the lifting of sanctions, for them, show them that it was not necessarily western sanctions that kept them live is so difficult, perhaps, but corruption within. so how would this be played out in iran going forward, do we think, in terms of the economy? limousine and we have been assessing is that there is certainly an aspect would on a run of certain sanctions that have been supporting the deal and continuing fluid, the satisfaction under

mandatory. and then there are those who have taken a harder line against the jcpoa, and are who have taken a harder line against thejcpoa, and are looking to discredit it or is it undermined. and that is what we will continue to see now that the us has pulled out. out of action or decision by the us not a part of that plays a dramatically. will see how this plays out. and of course there is a lot of detail and more analysis on our website. —— then we'll see how this plays out. we'll talk more about how it has been adjusted in the in the programme. but let us now turn our attention to argentina. argentina will hold key talks with the imf today in washington to try to secure financial help to the country. despite raising interest rates to llo%, the central bank hasn't been able to restore trust in the currency. our south america business correspondent, daniel gallas, has been following the story. but it has been trying to send all sorts of signals to the markets that it were let its national currency

depreciate. but that has not been working on of the governor disley in this to a new level. the imf to secure more money. some say around $30 billion are secure more money. some say around $30 billion are needed to protect the currency and also pay off their debt. that has a huge political cost of the president temer because many argentinians do not trust the international —— international monetary fund. this is notjust about securing trust and money, but also about the public at home but the plan will work out in the end. the southern indian state of karnataka is set to hold elections next week. four other indian states will also be holding polls this year before the national elections in 2019. but the recent cambridge analytica controversy has sparked a debate regarding the use of data analytics in elections and whether this could have a negative impact on indian democracy. the bbc‘s sameer hashmi travelled

to karnataka's capital of bangalore to find out more. the new battleground for indian elections. traditionally, politicians in india have relied on large public meetings like this to reach to out to voters. that is changing as leaders are now using online metrics to target voters and go after specific groups. now hundreds of start—ups have come up the last years like smart meter. there is awareness that it doesn't work any more and that is where we are seen as a possibility for

experimenting with new things. traditionally, political parties have grouped voters on parameters like religion, gender, age, language and class. but now some parties go further by looking for more specific characteristics and then targeting people to lobby for their votes. while data analytics firms are secretive about these parameters, we got access to some of these insights. political parties identify issues and preferences of small groups based on factors like professions, age, and educational levels. but individual data is hard to determine for now. the information is being used for microtargeting voters with customised communications like tailored messages on social media platforms. but some activists are worried about the rising trend. there is a fear that it might lead to more polarisation and false information being shared because it is difficult to monitor, and so, you know, microtargeting opens up the door for setting the future of a country in a manner

that is not necessarily ethical. five indian states including karnataka are holding polls this year. even as political parties continue with traditional campaigning, the use of data analytics is only likely to get bigger. sameer hashmi, bbc news, bangalore. now let's brief you some other business stories. google has unveiled artificial intelligence software that books appointments over the phone using its voice assistant. at its annual developers conference, the tech giant showed demonstrations of the software booking a haircut and then making a restaurant reservation by speaking to two human employees. disney's blockbuster film black panther has provided a boost to the company's sales. strong performance in its movie and theme park divisions helped to offset weakness in its tv operation. profits were up 23% compared to the same time last year. london has been rated as the best city in the world for university students.

the os university rankings are based on multiple factors such as the number of top universities in a city, the local job market and the diversity of culture. despite topping the league table, london performed poorly when it came to affordability. whoever you are in london, it costs you an arm and a lake, even if you area you an arm and a lake, even if you are a student. if you are russian oligarch, perhaps you can manage it a little better. and now what's trending in the business news this morning. a teenager in the moment a mixed picture following the announcement from the us. —— in the markets in asia at the moment, a mixed picture. backin asia at the moment, a mixed picture. back ina asia at the moment, a mixed picture. back in a moment. ‘s briefing coming up in the moment.

—— news briefing. a secret scotland yard "gang data base" is stigmatising and racially discriminating against young black men — according to a report by the human rights organisation, amnesty international uk. it's called the gang violence matrix and is under investigation by the information commissioner. the metropolitan police said the matrix was aimed at reducing violence and saving lives. our home affairs correspondent, june kelly reports. it was in 2011 writes that began in totte n ha m it was in 2011 writes that began in tottenham and spread across london that spawned the gangs matrix. police began compiling intelligence on individuals to have been identified as part of a gang, including those with no history of violence. the's report by amnesty international found that of the 3806 people whose details are held on the matrix, 99% are male, 78% are black,
