The United States dollar is suffering its worst start to a year in more than five decades, likely triggering a price hike for some everyday items and a jump in expenses faced by travelers abroad, some analysts told ABC News.

The U.S. dollar had its worst start this year in more than half a century. Harvard University economics professor Kenneth Rogoff says President Trump is accelerating the decline.

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.
