I read a lot from the press that as risk appetite wanes, USD rises. And I am confused.
Looking at in terms of Carry trade, it makes sense as USD now is the funding currency and as other target currencies get riskier, investors tend to return to funding currency to pay back the borrowing, requiring to convert back to USD and hence raising the currency.
But USD rose a great deal when the Lehman fell, when USD, in fact, was the target currency - which tells me looking in terms of carry trade is illogical.
Is it simply the case that in times global uncertainty US government bond is seen as the safest investment, thus investors rush into buy USD for US treasuries? What is the rationale behind thinking a country with large twin deficit is the safest economy?
+ can anybody offer some tips on getting a better sense of macro understanding ?
Thanks
