The euro rallied and the dollar retreated on Monday as investors pulled capital away from safe havens after US President Joe Biden and Russian President Vladimir Putin agreed in principle to meet to discuss the crisis in Ukraine.

The euro rose 0.5 per cent to $1.1376 after losing some ground in early trade while the dollar index shed 0.4 per cent against major currencies.

“The price action reflects a combination of relief that Russia did not invade the Ukraine over the weekend (…) and the announcement that Presidents Biden and Putin have accepted in principle a French proposal for a diplomatic summit”, wrote Lee Hardman, a currency analyst at MUFG.

Hopes that the crisis might be moving towards de-escalation was being felt through most financial asset classes, and European stock markets opened in positive territory.

The risk-friendly Australian dollar gained 0.6 per cent to $0.7218 and sterling ticked up 0.24 per cent to $1.3630.

By contrast, safe-have currencies which have benefited from the tensions spurred by Russia’s military build-up on Ukraine’s borders were on the defensive.

The Swiss franc lost 0.2 per cent against the euro while Japan’s yen gave up most of its early gains to trade at 114.93 per dollar.

While the outcome of negotiations to find a peaceful way out of the Ukrainian crisis remains uncertain, more volatility is expected ahead.

“The market is likely to keep chasing headlines without any clarity on the eventual outcome,” analysts at Barclays cautioned in a note.

Currency markets participants are also focused on central bank policy, seeking clues on the speed and size of interest rate hikes in major markets.

Investors will be closely watching remarks from US Federal Reserve policy makers this week for any hint that an expected rate hike at the Fed’s March meeting could veer more towards to 50 basis points instead of the current consensus for a 25 basis point increase.

Public remarks are also due from several BOE policy makers.
