日圓升值會否引發環球金融危機?

Don't see that at present apprecaition of yen does have much to do with carry trade. Please do not forget that the fiscal year for most of the Japanese Company is on March 31st., so a lot of large Japs company are buying yen back to boost it fiscal feagure.

If you could recall just within this 1 year, there are several time that yen sudden rise (around 3-5Yen within a week) against dollar sharply just for reason for US economic going to slow down, FED not going to rise rate, BOJ is going to rise interest rate ( just only at present 0.5% which most none Japan Company won't even bother even if BOJ will rise another 2-3 time this year, except for Japanese Bank and Japanese Company) or etc.

For carry trade effect buying yen sharply back to pay loan, it will only happen when the eqiuty market start to melt down just like the most update even on 2002 end of Q1.
