Donald Trump has pushed the dollar to its worst start to a year since 1973 after his trade policies rocked the American economy.

The U.S. dollar has had its worst start to a year since 1973, weighed down by President Donald Trump 's trade policy, a worsening outlook for the country's ever-growing public debt, and concerns about the independence of the Federal Reserve.

The greenback weakened 10.7% in the first six months of the year compared to a basket of currencies from major trading partners – the worst drop since 1973 when President Nixon stopped tying the dollar to the price of gold.
