Weekly Market Update: 6th November 2026
By Georgia Holmes
UK market update covering financial and economic developments, including the Bank of England’s rate rise, savings rates, Autumn Budget reaction, bank reporting requirements and AI-related fraud risks.
The UK financial landscape has seen several significant developments this week, with the Bank of England raising interest rates for the first time in more than three years. The increase to 4% is likely to affect mortgage borrowers and savers, while uncertainty around inflation and energy prices continues to influence the economic outlook.
Following last week’s Autumn Budget, questions are also emerging about the impact of changes to business taxation, particularly the new Founders’ Relief scheme. Meanwhile, banks face additional reporting requirements from HMRC, and financial services firms are increasingly looking at how to manage fraud risks associated with autonomous artificial intelligence.
Here are the key developments from this week and what they could mean for households, investors and businesses.
Bank of England raises interest rates to 4%
The Bank of England increased its base interest rate from 3.75% to 4% on 5 November, marking the first rate rise since 2023. The Monetary Policy Committee voted 8–1 in favour of the increase, responding to persistent inflationary pressures and higher energy prices linked to conflict in the Middle East.
UK inflation had reached 3.5% in September, and the Bank now expects it could rise to around 5% by the middle of 2027. Although the increase is intended to prevent higher energy costs feeding through into wider prices and wages, the Governor stressed that further rises are not inevitable.
The decision has immediate implications for borrowers and savers. Variable-rate mortgage customers could see repayments increase, while those with fixed-rate deals approaching expiry may face more expensive refinancing options.
Mortgage market reaction
Mortgage rates have already been under pressure ahead of the announcement, partly because of movements in financial markets and expectations of higher interest rates. More than 2.3 million households are expected to come off fixed-rate mortgage deals during 2027, potentially facing higher monthly repayments.
For prospective buyers, increased borrowing costs could further affect affordability and demand. Existing borrowers may wish to review their mortgage arrangements early, particularly if their current deal is due to expire.
The Bank has emphasised that future decisions will depend on how inflation develops, meaning borrowers and businesses should prepare for continued uncertainty around interest rates.
UK savings rates: are savers getting the best returns?
The Bank of England’s decision to raise interest rates could provide an opportunity for savers, although not all providers will necessarily pass the increase on to customers.
According to Moneyfacts, the best easy-access savings accounts were offering up to 5% AER on 5 November, while leading fixed-rate bonds also saw rates increase during the week.
However, many savers continue to hold money in older accounts paying considerably less. Moneyfacts estimates that customers keeping £20,000 in closed easy-access accounts could have earned £139 less over three years compared with those using accounts available to new customers.
With more than £306bn reportedly sitting in zero-interest current and savings accounts, reviewing existing arrangements could make a meaningful difference to the interest earned.
The recent increase in Bank Rate also makes it worth considering the balance…
