大学学的是财务管理，工作以及兴趣原因毕业后涉足金融领域，公司目前和花旗做了日圆和美圆的利率互换，其中有些产品背后的原理由于本人资历尚浅，看不懂，只好贴出，请大家为我分析一下到底是怎么构成的，

IF USD/JPY NEVER TOUCHS 123 FROM TRADE DAY TO EXPIRY DAY,

(1) IF FXEXP <= 112

XX(OUR COMPANY) MUST BUY USD and sell jpy with notional amount at 112

(2) 112<=FXEXP <= 114

no DEAL WOULD HAPPEN

(2) 114<=FXEXP <= 123

XX can buy usd and sell jpy with notional amount at 114

IF usdjpy EVER TOUCH 123 FROM TRADE DAY TO EXPIRY DAY,

(1) IF FXEXP <= 114

no deal would happen

(2) 114<=FXEXP <= 123

XX can buy usd and sell jpy with notional amount at 114

(3) IF FXEXP >= 123

There will be no transaction between XX and citi bank except that citibank will pay xx rebate amount

就是以上这些了，请大家指点
