Three is not anything clear to account for the pop in the Australian and New Zealand dollars
Newswires not carrying anything to indicate a catalyst
We had retail sales data earlier, showing a panic-buying induced surge. This might be enough to return a positive GDP reading for Q1, maybe that's helping AUD ? (I'm only floating that out there, not convinced).
Without a clear catalyst sometimes the best explanation is 'more buyers than sellers' (which infuriates market dynamics pedants but you know what I mean).
