The Bank of England kept rates unchanged, a widely expected outcome given that just 2bps of tightening had been priced ahead of the decision. Policy signals, however, continued to point towards another rate increase in November, according to MUFG’s reading of the vote dynamics, while attention shifted to an unexpected overhaul of quantitative tightening.
Under the revised plan, sales were paused in parts, longer-dated Gilts will be held on a permanent basis, and a defined block of bonds will be run down via a new route. Around GBP 146bn of Gilts maturing between 2035 and 2049 is set to be sold at a pace of GBP 20bn per year, with those bonds transferred directly to the government through the DMO rather than auctioned into the market as under previous QT. Following the announcement, the 30-year Gilt yield fell by 12bps, while sterling declined on the day, with the new framework reducing long-end yield risks ahead of the 28 October budget.
Impact of QT Overhaul on Gilts and Derivatives
We believe the Bank of England’s unexpected quantitative tightening (QT) overhaul has fundamentally changed the playing field for sterling and Gilt derivatives. By routing £20 billion of long-dated Gilt sales annually directly to the Debt Management Office rather than dumping them on the open market, the central bank has effectively put a safety net under long-end yields. This strategic shift has already cooled the 30-year Gilt yield by 12 basis points, signaling a much calmer environment for fixed-income markets.
For interest rate swap and options traders, we recommend positioning for a flatter Gilt yield curve as long-end risks continue to recede. With the 10-year Gilt yield currently stabilizing around 3.95% and the 30-year yield compressing, long-dated receiver options look increasingly attractive. We should also expect implied volatility on long-term sterling swaps to drift lower in the coming weeks as the market digests this new supply mechanism.
Sterling Market Prospects Ahead of the Autumn Budget
With the UK autumn budget scheduled for October 28, the currency options market is already pricing in a smoother ride than during previous fiscal events. Historical data from the 2022 “mini-budget” crisis shows how quickly Gilt volatility can wreck the pound, but current sterling one-month implied volatility remains highly stable near 7.8%. We suggest derivative traders leverage this calm by buying sterling call options, targeting a push toward the 1.3300 level against the US dollar as downside fiscal risks are now heavily mitigated.
Additionally, with a majority of policymakers still favoring tighter monetary policy, a rate hike this coming November remains highly probable. Short-term sterling futures are currently pricing in only a minor chance of a hike, leaving room for a sharp hawkish repricing if upcoming inflation data surprises to the upside. We advise maintaining long exposure to the pound to capitalize on this supportive yield environment over the next month.
