• All eyes on currency markets for early read on risk appetite
• Japanese yen, Swiss franc edge higher in early Monday trading

Global financial markets are poised for another week of volatility, as traders close out a dizzying month in which worries about US and European lenders dominated sentiment and complicated central banks’ fight against inflation.

The Japanese yen and Swiss franc edged higher against the dollar as the trading week got underway in early Sydney. Traders focused on haven assets after Russian President Vladimir Putin’s comments on Saturday about stationing tactical nuclear weapons in Belarus. The euro was little changed after European Central Bank Vice President Luis de Guindos said the uncertainty in the banking sector means the central bank will take a meeting-by-meeting approach on interest rate policy.
