Bank of England MMC, March 2026: rate expectations shift as sterling funding markets hold steady

What the source announced

The Bank of England set fixed spreads above Bank Rate for its Discount Window Facility in March 2026: +15 basis points for Level A collateral, +25 basis points for Level B, and +50 basis points for Level C (Bank of England MMC Minutes, March 2026).

The Money Markets Committee met in March 2026 as sterling money markets were absorbing the effects of conflict-related energy moves and their macroeconomic implications (Bank of England MMC Minutes, March 2026). Committee discussion covered three main areas: the volatility itself, shifts in market-implied central bank policy expectations, and the condition of sterling funding markets.

On the third headline theme, the committee found sterling funding markets resilient. Repo rates held within their usual ranges and unsecured rates remained largely steady throughout the period of broader volatility (Bank of England MMC Minutes, March 2026).

Taken together, the March picture was one of external shock absorbed by a stable funding system: conflict-related energy moves and their macroeconomic implications pushed market-implied central bank policy expectations to shift, while repo and unsecured funding markets continued operating within their normal parameters (Bank of England MMC Minutes, March 2026).

What this means for your mortgage

The DWF spread recalibration has no direct impact on retail mortgage rates. The facility operates as a backstop that banks and building societies can draw on when short-term funding pressures arise; fixed, predictable spread pricing reduces the uncertainty around what that backstop costs, which in turn lowers the risk that a funding squeeze is passed through to retail mortgage pricing.

For fixed-rate mortgage borrowers, the shift in market-implied central bank policy expectations is the more direct pricing signal. Swap rates, which underpin fixed mortgage product pricing, track where markets expect Bank Rate to land over the next two to five years. When the market prices in fewer or later rate cuts, swap rates tend to rise, and lenders adjust their fixed-rate deals, often before any formal Monetary Policy Committee decision.

Borrowers on tracker or standard variable-rate mortgages receive a different signal. The committee's finding that repo rates remained within usual ranges, even as energy-linked volatility moved macroeconomic and policy expectations, indicates that the wholesale funding floor beneath variable mortgage rates held steady during the period. If your fixed-rate term ends within the next six months, comparing the standard variable rate against available fixed deals for your specific loan size and remaining term gives a concrete cost figure rather than a general estimate.
