Presently up at 1.5865, garnering some underpinning from sell-off in EUR/GBP which is down at .8375 from early .8410.
Late last week I was getting reports of 1.5900 barrier option interest, and have no reason to suspect that interest has suddenly disappeared.
Some focus already on tomorrows UK CPI release for December, median expectations calling for +0.7% m/m, +3.4% y/y. That said, some forecasts are calling for an appreciably higher y/y number. If they prove correct, then already high expectations of an early UK rate hike will be bolstered further. This would most probably result in further sterling strength.
