Dollar rises slightly on Trump's decision to dismiss Bolton

US dollar rose today as the markets are closely following the impact of Trump's decision to sack his national security adviser.

Trump said via his Twitter account that he had fired national security adviser John Bolton as the White House is no longer needs his service.

Trump added that there are deep fundamental disagreements between him and Bolton, which led to his dismissal and he will nominate a new figure for the post by next week.

Some interpreted that is due to Bolton refusal to open any dialogue channels between the US and Iran on its nuclear program.

The markets are also anticipating the ECB interest rate decision this week with forecasts of another rate cut to support the European economy.

By 18:53 GMT, US dollar index rose by 0.1% to 98.3 points, with an intraday high of 98.4 and a low of 98.2.
