Nationwide, TSB, Accord and Principality all raise mortgage rates as swap rates climb ahead of the September MPC

Nationwide raised selected fixed and tracker rates by up to 0.20% on 9 September, taking its cheapest two-year fix from 4.48% to 4.63%, while TSB added 0.15% across its fixed-rate purchase range, Principality up to 0.18% on selected residential deals and Accord up to 0.16% on buy-to-let. Lenders price fixed deals off swap rates, and two-year swaps have drifted up to around 4.18% as markets reassess how far Bank Rate will fall from 3.75%, with the next MPC decision due on 17 September. For buyers, the practical effect is that the cheapest deals of recent weeks are being pulled rather than replaced, so anyone part-way through an application should check whether their quoted rate still stands; for sellers, dearer borrowing quietly trims what the same buyer can offer. This is a repricing rather than a reversal, measured in basis points on selected products rather than across whole ranges, and other lenders were still cutting in the same week.
