GBP/USD jumped up to a high of 1.2772 in the last half-an-hour

I'm searching for any headlines to have caused the jump but I'm not really seeing anything so far. It's not a major spike by any means - about 20-odd pips - but so far the jump in cable is still holding near the highs.

GBP/JPY is also marked higher now to 140.80 levels after having reached a low of 140.25 earlier in the session. August/Summertime markets tend to be full of surprises like this at times, so I wouldn't look too much into things if the jumps aren't caused by news/headlines.
