Barclays expects strong dollar buying at the end of the month and quarter.

Barclays' month-end foreign exchange flow model indicates that the US dollar will see strong buying against all major currencies, with month-end and quarter-end factors especially favoring the Canadian dollar, Australian dollar, and Scandinavian currencies. Fund managers adjusting their portfolios typically sell US dollars when US assets perform well to bring their asset allocation back to target levels; conversely, they buy US dollars when US assets underperform (provided they maintain hedging).
