The British Pound has been in meltdown mode for the past three weeks, following rate hike expectations every step of the way. On April 19, odds of a 25-bps hike at the May policy meeting were still at 85%, and GBP/USD above 1.4300. But since then, GBP/USD has dropped closer to 1.3500, culminating in the BOE's May decision to keep their main policy rate on hold at 0.50%.

This has been a dramatic change in fortunes, no doubt. And despite BOE Governor Mark Carney's suggestion that a rate hike will still happen at some point this year, traders seem to have embodied the mantra “once bitten, twice shy.”

Rates markets are only pricing in 19-bps of tightening for the remainder of 2018, with the November policy meeting – one of the four per year that is accompanied by a new Quarterly inflation Report (QIR) – being seen as the most likely period for when the hike would occur (64% implied probability).

If the “once bitten, twice shy” mantra is indeed the motif for traders now, then it will take more than Governor Carney's suggestion of a hike to move pricing. Indeed, between the dismal Q1'18 UK GDP report and recent inflation (CPI, PPI, and RPI) trends, traders will want to see hard evidence that economic data is back on track before taking any more policy officials at face value about the timing of another rate hike.

With rate hike odds continuing to erode, this leaves the British Pound in a difficult situation. Technically, the damage has been significant as well: a double top may now be in the works. Price broke the uptrend dating back to the January 2017, with momentum accelerating to the downside: price is below the daily 8-, 13-, and 21-EMA envelope, with MACD and Slow Stochastics trending lower in bearish territory.
