同学你好，
首先回忆一下total return=Rdc+Rfx
invest in UK（5yr） and borrow USD（6mon）
invest in UK（5yr）的return=1.1%
borrow USD（6mon）的return=1.4%
Rdc=（1.1%-1.4%）/2=-0.15%
（这里除以二是因为我们算的return是for 6mon）
Rfx=1%因为GBP对于USD是升值1%，所以我们拿着invest in UK赚到的GBP转换成USD的时候，会给我们带来额外的return。
所以total return=-0.15%+1%=0.85%
希望对你有帮助～

The highest potentireturn, 0.85%, reflects borrowing USfor 6 months anbuying the UK 5-yebon The carry component of the expectereturn is actually a loss of 0.15% [= (1.10% – 1.40%)/2], but this is more thoffset the 1% expecteappreciation of Gversus US A muhigher carry component +0.90% = (1.95% – 0.15%)/2 coulobtaineborrowing for 6 months in EUR to buy the US 5-yenote, but thaantage woulmore thoffset the expecte1% loss from preciation of the US(long) against the Euro (short).

C is incorrect. This answer (+0.90%) is the highest potenticarry component of return but ignores the impaof currenexposure (being long the preciating USanshort the appreciating Euro). 用中文一下b，不是最高是0.9%，为啥子不选c呢？
