Money markets are pricing in a rate hike by the central bank at its meeting on Nov. 4.

However, data from the UK last week was mixed: business activity surveys showed improvement as the economy unexpectedly regained momentum in October, but retail sales figures were worse than expected, sending the pound lower at the end of the week.

A record proportion of the British public thinks inflation will accelerate over the next 12 months.

"I can't persuade myself that the FX market is going to blindly buy sterling on rate hikes that are down to supply-side inflationary pressures (Brexit having made sure the UK feels these particularly sharply) against the backdrop of a dismal run of falling monthly retail sales figures," Kit Juckes, a currency strategist at Societe Generale, said in a client note.

Bank of England policymaker Silvana Tenreyro said she needed more time to judge how the end of the government's job-saving furlough scheme was affecting the labour market and said a rise in inflation pressures from surging energy prices was likely to fade quickly.

At 1536 GMT, the pound was up 0.1% against the dollar at $1.3773, having fallen below $1.38 after Friday's retail sales miss.

Versus the euro, it was up around 0.3% at 84.34 pence per euro.

On Friday, the trade-weighted sterling index hit its highest levels since June 2016, when it dropped sharply on the UK's Brexit vote.

Speculators switched to a small net long position on the pound in the week to Oct 19, positioning data from CFTC showed. For most of October, short positions have outnumbered long.

Some investors believe that policymakers may be making a mistake by tightening policy too quickly, making the British currency more volatile than major rivals in recent days.

George Buckley, chief UK and euro area economist at Nomura, said that rising COVID-19 case numbers in the UK and the risk of renewed restrictions on activity during winter could push the Bank of England not to raise rates in November.

The UK's budget forecasts will be unveiled on Wednesday.

"Our initial thoughts are that this week will not see any major announcement on fiscal consolidation strong enough to prompt a more dovish re-pricing of the BoE cycle," ING FX strategist said in a note to clients.

British Brexit minister David Frost said on Monday that the European Union's proposals to solve the problem of trade involving Northern Ireland did not go far enough and significant gaps remained between the two sides.
