The dollar index (DXY00) today is unchanged. The dollar index is being undercut today as oil prices fell back by about -3%. Also, the 10-year T-note yield is down by about -3 bp after posting a new 1.5-year high earlier in the session. The dollar has underlying safe-haven support as the market is braced for a possible expansion of US military attacks on Iran, which President Trump said he is considering.
The dollar has safe-haven demand after the Iran-backed Houthis on Thursday launched a missile and drone attack on two Saudi Arabian oil tankers in the Red Sea, expanding the oil disruptions beyond the Strait of Hormuz and threatening oil shipments in the Red Sea. President Trump responded by saying he will hold Iran responsible for the Houthi attacks and telling Axios in an interview on Thursday that he is considering a "massive attack" that would be "bigger than ever before" and is "close to making a decision on it."
