Models point to dollar strength
Virtually every big-bank model is out with a report saying that month-end rebalancing will lead to US dollar strength into the 31st. That's essentially been the story today (aside from NZD) and it will be something to watch out for through Wednesday.
Of course, broader equity market volatility is the bigger story and that's what's driving the moves but if somehow markets calm down for the next two days, watch for a USD tailwind.
