FX: European open; The dollar was mixed in holiday-thinned Asian trade Monday, higher against the yen, but giving up further ground against the euro. Euro-dollar traded to a session high at $1.2208, after a very early brief dip to session lows at $1.2110. Traders say offers are noted building above $1.2220. Dollar-yen was trading at Y91.88, just shy of the session best levels at Y91.97, as a return of risk appetite again helped sentiment, regional equity markets and US futures traded in the black. However, traders said volumes were muted ahead of the BOJ meet later in the week (China and Australia holidays today). Aussie was pulled higher by the euro-dollar spike rally, though managed to hold gains while the euro pared early gains, slipping back into a $1.2170/90 range. Kiwi edged to $0.6943 from $0.6905 despite NZ retail sales disappointing. UK OBR growth forecasts at 0900GMT with EMU IP to be released at the same time. SNB Rate decision Thursday seen as the week's highlight, no change expected by market looks for comment on intervention policy. US data calendar light today.
