New York: The US dollar fell Tuesday, approaching its lowest level in years against the euro and the Swiss franc, affected by US President Donald Trump's sharp criticism of Federal Reserve Chairman Jerome Powell and concerns about the bank's independence.

According to Qatar News Agency, economic analysts confirmed that the dollar is in a very fragile position amid market fears of tariffs imposed by the US administration, which threaten to spark a global trade war. They explained that doubts about the independence of the US central bank threaten the value of the dollar as a reserve currency.

The US currency's losses accelerated after the Thai Prime Minister announced the postponement of trade negotiations with Washington, which were scheduled to begin Wednesday. Trump escalated his criticism of Powell on Monday, demanding that he cut interest rates or risk an economic slowdown.

Beijing also accused Washington on Monday of abusing tariffs and warned countries against striking broader economic deals with the United States at its expense, escalating its rhetoric in the escalating trade war between the world's two largest economies.

The dollar fell 0.03 percent to 140.820 yen, after earlier falling below the psychological level of 140 for the first time since mid-September. The dollar rose 0.57 percent to 0.8138 Swiss francs, close to the 10-year low of 0.8042 reached in the previous session. The euro fell 0.38 percent to 1.1467, after jumping to 1.1573 yesterday for the first time since November 2021.

The dollar index, which measures the performance of the greenback against six major currencies, rose 0.256 percent to 98.599, after falling to 97.923 in the previous session, a level not seen since March 2022.
