NEW YORK, Aug. 6 (Xinhua) -- The U.S. dollar index increased against other major currencies in late trading on Monday, as investors digested the U.S. decision to resume sanctions against Iran.

The White House said in a statement Monday that the United States will reactivate a slew of sanctions on Iran's financial and industrial sectors beginning on Tuesday.

The action, followed by another set of sanctions scheduled for November, will bring U.S. sanctions against Iran to the level on par with those prior to a major multilateral nuclear deal reached in 2015.

The first batch of sanctions target Tehran's purchase of U.S. banknotes, trade in gold and other precious metals, as well as the use of graphite, coal, aluminum and steel in industrial processes.

Another round of sanctions, to be reinstalled in November, will be on Iran's port, energy and shipping sectors, its petroleum-related transactions, and foreign transactions with the Central Bank of Iran, according to the statement.

Some analysts said that global uncertainties are dollar positive as the greenback is seen by some investors as a safe-heaven currency.

There is no major economic data due out on Monday.

The dollar index, which measures the greenback against six major peers, increased 0.22 percent at 95.3546 in late trading.

In late New York trading, the euro decreased to 1.1553 dollars from 1.1579 dollars in the previous session, and the British pound was down to 1.2943 dollars from 1.3009 U.S. dollars in the previous session. The Australian dollar fell to 0.7389 dollar from 0.7404 dollar.

The U.S. dollar bought 111.39 Japanese yen, higher than 111.23 Japanese yen of the previous session. The U.S. dollar increased to 0.9963 Swiss franc from 0.9940 Swiss franc, and it rose to 1.3001 Canadian dollars from 1.2981 Canadian dollars. Enditem
