And bond traders set off global currency markets as they voiced their displeasure of the state of monetary policy in Japan.
The Reserve Bank kept the cash rate on hold, at 2.75 per cent, before the release of weaker than expected economic data that showed mixed fortunes in the economy.
The mix of negative data had analysts using phrases such as "tipping point" and "fundamental correction".

"I think we were at that classic tipping point, where we only needed one piece of bad news ... and that was it."
Nomura strategist Tim Rocks said: "I think the market's in a transition from a honeymoon period about quantitative easing to a much more realistic assessment.
