While this week is full of important events that can have an impact on the financial markets, the news is dominated by the Iran nuclear deal controversy.
The Iran deal prevents the country from developing its nuclear program (i.e. keeping its nuclearization at a minimum), while offering access to foreign markets for Iranian exports. In the last couple of years this has allowed Iran to become one of the major oil exporters in the world.
However, Trump’s administration has expressed skepticism towards the deal with Iran. This has led analysts to speculate that Trump will not renew the deal before the May 12 deadline. He is under pressure from European countries who support the Iran deal.
President Trump tweeted that he would make his decision known today at 18:00 GMT. Considering the importance of this announcement, it is likely that the markets will experience a lot of volatility around that time.
