Francesco Pesole, FX Strategist at ING, reports that all G10 currencies except sterling saw a net increase in speculative positioning against the U.S. dollar in the week ending 4 May, a sign that USD bearish sentiment is rising again. 

"CFTC data on speculative positioning ending 04 May provided clear indications that USD bearish sentiment is consolidating again. The aggregate USD positioning vs reported G10 currencies (i.e. G9 excluding Norway's krone and Sweden's krona) moved deeper into net short territory for a fourth consecutive week, with net shorts now worth 6% of open interest."

"All currencies except GBP saw an increase in their net positioning versus the USD in the week ending 04 May. While euro positioning was only marginally changed, currently at +13% of open interest, the yen saw some trimming of its very wide net shorts, possibly aided by the more stable environment for Treasury yields. That said, there is still considerable room for JPY shorts to be unwound considering that it is the only currency with a net short positioning in the G10, currently worth 27% of open interest, although much will depend on the moves in US yields over the coming weeks."

"With the commodity space being broadly supported of late, CAD and NZD continued to see a larger increase in their net longs compared to their closest peer, the Australian dollar. CAD net longs are currently worth 13% of open interest, NZD net longs 19%, both being at the top end of their one-standard-deviation band."

"Sterling was the only currency that experienced a drop in its net positioning in the week ending 04 May, as its net long positions were trimmed by 5% of open interest, and are now worth 13%."

"There is a possibility that the recent political noise in the UK - with Prime Minister Boris Johnson at the centre - has prompted some speculative investors to cash in on their long GBP bets given the perceived higher risk of political instability in the country. What might also explain the long-squeeze in sterling is that part of the market may have positioned for a less hawkish message by the Bank of England on Thursday and possibly an outcome from the Scottish elections that could have raised the risk of a new Independence Referendum."
