Donald Trump is probably to blame for a weak dollar

Last year, the US dollar lost 10 per cent against the euro and 5.5 per cent against the renminbi. It was the second worst performer among major currencies after the New Zealand dollar, and its drop was the steepest in more than a decade despite three interest rate hikes and the passage of Trump's tax reform, which could logically be expected to drive the dollar's value upward. This happened for a complex set of reasons which may include the dollar's popularity as a funding tool for foreign companies and governments, but Trumps's effect on his country's global standing must be a key driver of the dollar's decline.

All year, the Trump administration has blown hot and cold on its commitment to alliances, to the point that any assurances it makes today can't be taken at face value. Trump's quick temper and his willingness to play the "whose nuclear button is bigger" game haven't helped bolster the US reputation as a security guarantor. The constant leaks pointing to Trump's incompetence, such as the new Michael Wolff book, appropriately titled "Fire and Fury," also detract from the dollar's reputation as a safe asset.
