In Tokyo on Monday, the dollar was trading just below a three-week high against major currencies as investors waited for more clarity on the next round of tariffs from U.S. President Donald Trump. The euro saw a slight increase after declining for three consecutive sessions, while the yen dipped against the dollar due to rising U.S. Treasury yields.

The U.S. dollar index, which compares the currency against six others, held steady at 104.03 after reaching 104.22 last Friday, marking its first increase this month. The dollar has faced downward pressure this year as concerns grew over Trump's trade policies potentially causing an economic downturn.

The upcoming tariffs announcement on April 2 will see the White House imposing reciprocal levies on multiple countries, raising uncertainty in the market. Although dollar forecasts were revised down last week, Goldman Sachs analysts still anticipate some dollar strength from current levels due to projected growth outlook shifts.

The dollar strengthened against the yen by 0.3% and the euro rose by 0.24% to $1.0836, bouncing back from a recent low. The euro had surged last week on optimism fueled by Germany's plans to relax fiscal rules, but the currency trend reversed as the actual implementation faced hurdles. With the focus now shifting to the impact of potential tariff changes, market analysts are closely monitoring future developments.
