NEW YORK: The US dollar fell to two-week low against a basket of currencies and a seven-month low against the Japanese yen as surging stock markets reduced demand for the greenback, and before the Federal Reserve will conclude its two-day meeting.

Democrat Joe Biden edged closer to victory over Republican President Donald Trump in the US presidential race as election officials tallied votes in the handful of states that will determine the outcome and protesters took to the streets.

But the so called "blue wave," where Democrats also take control of the Senate in congressional elections, looked unlikely. Wall Street's main indexes jumped as investors bet that a Republican-held Senate would block any moves by a Biden administration to tighten regulation and raise taxes on corporate America.

The dollar index fell 0.74% against a basket of currencies to 92.71. The euro jumped 0.78% to $1.1813. The dollar dropped 0.78% against the Japanese yen to 103.67 yen, the lowest since March 12, and breached technical support at 104 yen that will now likely form resistance.
