The US dollar has regained its upward momentum due to concerns about escalation of war with Iran.

Sina Finance reported on March 30th that concerns about the escalation of the Middle East conflict have pushed up oil prices and hit risk appetite, causing the US dollar to rise again. Earlier, the yen strengthened as Japanese officials issued increasingly more warnings about potential intervention measures to support the yen, causing the dollar to slightly decline. However, due to the dollar benefiting from its safe-haven role and the United States' position as a net oil exporting country, its decline was not significant and short-lived. Chris Turner of ING Group said in a report, "Unless Iran sends out any clear reconciliation signals, it is difficult to see the dollar relinquishing its gains this month in the short term." The DXY dollar index rose 0.1% to 100.287, close to the two-week high of 100.342 touched overnight.
