GBP Stabilisation Hinges on Gilt Yield Support – BNP

BNP Paribas expects the British pound to stabilise as gilt yields rise. The call ties sterling's near-term trajectory directly to the UK bond market, not to growth surprises or Brexit headlines. When gilt yields climb, the rate differential between UK and other developed-market bonds widens. That shift makes pound-denominated assets more attractive to foreign capital. Capital inflows, in turn, support GBP/USD.

The bank's forecast implies the current yield backup is not a temporary spike. If gilt yields hold at these levels or move higher, the pound should find a floor against the dollar and the euro. A stabilisation, rather than a rally, suggests BNP sees the upside as limited by lingering uncertainty around UK inflation persistence and the Bank of England's next policy move. The trade is a conviction in the bond channel, not a bet on faster UK growth.

Gilt Yields and the Pound: BNP Paribas' Framework

The naive interpretation of sterling weakness is that it reflects a weak UK economy. That view is incomplete. The better market read starts with rate differentials. The pound has been under pressure because the BoE has signalled a slower cutting cycle than the Federal Reserve. That relative hawkishness has not been enough to lift GBP because global risk appetite and US exceptionalism have dominated. What changes when gilt yields rise is that the UK-specific carry trade becomes more attractive. Higher gilts improve the risk-reward for holding GBP, even if the growth backdrop remains sluggish.

Positioning data suggests speculative accounts have built sizeable short positions in sterling. A stabilisation driven by higher yields could trigger a squeeze, accelerating the move. The key variable is whether gilt yields stay elevated or revert lower. If the BoE pushes back against market pricing for rate cuts, yields could climb further. If inflation data softens, the opposite happens. BNP's view is that the balance favours bond support for the pound in the near term.
