The US dollar will weaken against most major currencies this year as the interest rate gap with its peers stops widening, putting the currency on the defensive after a multi-year run, according to a Reuters poll of foreign exchange strategists.

Despite starting the year on a weak footing, the dollar bounced back sharply in February, gaining nearly 3 Per cent for the month, on expectations the US Federal Reserve would take interest rates higher than previously thought.

However, the failure of two regional US banks in March forced the Fed to temper those expectations, pushing the greenback to retreat and give back nearly all of its previous month's gains, a trend likely to persist in the near-to-medium term.

While fears over market turmoil related to banks have subsided, hawkish interest rate expectations have not returned, suggesting a run of rapid rate rises may soon end, and with it, the beginning of the end of an historic dollar bull run.

Median forecasts in the March 31-April 4 poll of 90 foreign exchange strategists showed the dollar ceding ground to all major currencies in a year.

Highlighting the outsized role interest rates play in currency movements, a majority of analysts, 32 of 56, who answered a separate question said rate differentials will drive the dollar the most over the coming month.

"Our take on the dollar is that we continue to look for further weakness over the next three to six months. I guess recent developments have been the loss of confidence in the US regional banks, which has increased downside risks to the dollar," said Lee Hardman, currency economist at MUFG.

"The Fed will be very aware of those downside risks to growth going forward. So we kind of agree with the dovish repricing that's taking place in the US rate markets. We think the Fed is closer to the end of their hiking cycle."

Fed funds futures showed markets were pricing in a rate cut to come as early as September despite inflation still running well over double the Fed's target.

With the dollar's expected retreat, the European single currency is finding its spot in the sun after briefly crossing below parity on lagging rate expectations in 2022.

Up 2.5 Per cent this year, the euro was forecast to trade around current levels of $1.09 in the next one to three months and then strengthen another 2 Per cent to change hands around $1.12 in 12 months.

Despite gaining more than 2.5 Per cent in March, the Japanese yen is still down 0.6 Per cent for the year. The safe-haven currency, which hit 32-year lows in 2022 again on rate differentials, was forecast to recoup that loss over the forecast horizon.

The median view showed the yen gaining nearly 6.0 Per cent to trade around 125.00/dollar in 12 months.

While the dollar's weakness was a welcome change for most currencies, especially for emerging market currencies which were forecast to post modest gains from here, the projected upside from current levels was limited.

With the dollar remaining defiantly strong against analyst expectations for years, some were reluctant to call for the world's reserve currency to weaken rapidly. Indeed, the 12-month median view for nearly all of the major currencies surveyed was identical with the March poll.

"We are more optimistic than the consensus for the dollar," said Adam Cole, head of FX strategy at RBC Capital Markets, who described his position as moving from outright bullish over the past two years to something more nuanced.

"Our overall bias is that the consensus for big dollar losses is likely to be wrong again," he said, saying he did not believe the Fed would deliver the steep rate cuts the market is pricing for.

That would only happen if a punishing recession were to take hold, a scenario which Cole said "tends to be a dollar positive scenario anyway."
