The main currency pairs have declined slightly from their recent trajectories. On Friday, the dollar edged lower from its recent 20-year high, but it was still on track for its best month since 2015.

At 10:47 GMT, the Dollar Index was down 0.6% on the day, to 102.98, but it is still ready for a 4.8% gain in April. The dollar's decline gave a boost to other major currencies, with the euro up 0.6% on the day to $1.05655. Still, the euro was on track for a monthly decline of 4.5%, its biggest drop since 2015. The euro has lost about 6.6% against the dollar since Russia invaded Ukraine on February 24.

The dollar-yen remained above the key psychological level of 130, at 130,085, after breaking through 130 for the first time in 20 years. Meanwhile, the pound edged up to $1.2572 due to the weakening dollar, but it was still set for its biggest monthly decline since 2016.
