sure, but if the main flow of the day is buying eur/jpy, which it looks like it might have been, demand is for buy eur/usd AND buy usd/jpy, so we've seen both go up.
BUT eur/usd side seems to have more offering liquidity, hence usd/jpy has been the one to pop.
To me this infers USD has an underlying bid tone.
this view partially confirmed by gbp/usd selling pressure
