The yield on Italian 10-year government bonds rose 13 basis points to 6.14 per cent having earlier touched on a 14-year high of 6.25 per cent. Italy is Europe's biggest bond market, and has the second highest debt to GDP ratio in the euro zone after Greece.
"It's one thing to bailout the smaller peripheral euro zone countries, but with Italy, the current mechanism will just not be able to cope," Goh said. "The renewed jitters in Europe might prompt people to reassess the kiwi, and if we keep getting risk off as week progresses, I think we'll see a lot speculators bail out on their long positions."
The kiwi recently traded at 86.81 US cents, down from 87.38 cents yesterday, and fell to 74.47 on the trade-weighted index of major trading partners' currencies from 74.84.
It was little changed at 80.26 Australian cents from 80.27 cents yesterday, and fell to 66.95 yen from 67.43 yen. It declined to 61.18 euro cents from 61.56 cents yesterday, and slipped to 53.27 pence from 53.64 pence previously.
The average winning price at the GlobalDairyTrade auction fell 1.3 per cent to US$3,716 per tonne. Prices for whole milk powder eased 0.3 per cent, offsetting moves for other dairy products.
The kiwi may trade between a range of 86.44 US cents and 87.20 cents, Goh said, with the currency likely to undergo further consolidation.
