The society launched the new deal with rates at 2.89% for new customers and 2.79% for existing customers in conjunction with its lowest ever three and five-year fixed rates, the three-year starting at 1.99% and five-year starting at 2.34%.
First Direct is the only other lender that currently offers a 2.89% 10 year fix
Nationwide's Flexclusive four-year fixed rate up to 60% LTV has also been reduced to 2.14%
Richard Napier, Nationwide's director of mortgages and savings, said: "This new range of fixed rate mortgage deals ensures Nationwide remains competitive, including for those with smaller deposits. They are designed to appeal to both first-time buyers and those looking to remortgage, offering certainty of mortgage payments while interest rates remain at a historic low.
We are also responding to customer demand for higher LTV products, such as our Save to Buy mortgage deals for customers with a 5% deposit, with a two-year fixed rate now under 4% and an offer of up to £1,000 cashback."
