Actually to be honest it's kind of the other way round imho. Eur/usd ran into good bids below 1.4600 just as usd/chf ran into even better offers 1.0995. This turned on a dime and magnetic CTA stops around 1.0950/55 level caught the market's eye, seeing eur/usd paid up to the 30s. Meanwhile cable started playing catch-up early London time before accelerating to the downside on the weak-ish UK manufacturing data. EUR/GBP feels a little like it's caught in the crossfire of all this. And of course we're waiting on the ECB and BoE today. unch and -25 have kinda been priced in, and not much differs today, so people aren't suddenly gonna wake up this morning out of the blue and go 'ooh - rate divergence - buy eurgbp'
Could be wrong of course, but to me eurgbp felt like the tail, not the dog this morning
My $0.02 as always
