Bond navigators: Spring Statement 2026 and what really matters for gilts

The Spring Statement delivered by the Chancellor of the Exchequer was exactly in line with what the markets expected, a quiet, policy light event designed to avoid surprises.

The Government stuck to its commitment to run only one major fiscal event per year, and the result was a steady set of macro forecasts, marginally improved fiscal headroom, and no major tax or spending shifts.

Chancellor Rachel Reeves was clear these forecasts may need to be revisited, given the escalating conflict in Iran and the resultant sharp rise in energy prices.

The Office for Budget Responsibility (OBR) left its medium-term growth and inflation forecasts broadly unchanged. Further, growth was expected to soften in the near term and unemployment was expected to rise but forecast indicated that inflation will target sooner, and the medium-term outlook remains stable. Stronger tax receipts have also helped ease borrowing pressures and lift the chancellor’s fiscal headroom above £23bn. However, Chancellor Rachel Reeves was clear these forecasts may need to be revisited, given the escalating conflict in Iran and the resultant sharp rise in energy prices, meaning the near-term outlook could shift if current conditions persist.

Gilt supply – not what it first appears

For the bond market, the real significance lies not in the policy announcements but in the implications for gilt supply, with attention centred on the 2026-27 remit. Although borrowing has been revised lower, the improvement fell short of market expectations, leaving the Debt Management Office (DMO) remit at £252bn (£52bn lower than last fiscal year) and prompting some initial disappointment. However, January’s strong tax receipts and lower debt costs were not captured in time, meaning the funding need is likely overstated – a downward revision later in the year on 23 April looks likely.

Within the remit, supply remains concentrated in short-dated gilts (38.6%) and medium-dated gilts (30.9%), with lighter allocations to the long end (9%) and linkers (9%). But the real story is the record high 12.1% unallocated reserve, which gives the DMO flexibility to shift issuance toward the sectors with the strongest liquidity and demand – a tool that proved crucial in keeping the gilt market functioning smoothly through 2025-26. The standout development was the possible return of switch auctions for the first time since 2000-01.

DMO flexibility increases

For context, the DMO typically issues gilts via auctions (frequent, market priced sales) and syndications (larger, bank led deals for placing longer dated supply). A switch auction is where the DMO buys an old gilt and simultaneously sells a new one, helping improve liquidity, build size in benchmark maturities and manage the curve without increasing total net supply. Additionally, the announced syndication programme of two medium-dated, three long-dated and two linker deals, allows the DMO to deliver larger, well-timed blocks of supply in a controlled way, where demand is deepest. Taken together, the sizeable reserve, the availability of switch auctions after the first quarter of the remit and continued role of syndications mean that, although the headline remit initially disappointed, the eventual distribution of supply could prove more gilt-friendly than the initial numbers suggest.

The eventual distribution of supply could prove more gilt-friendly than the initial numbers suggest.

In regard to Treasury bill contribution, the DMO set it at just £5bn, a notably low figure that reflects its continued caution around expanding the short-term funding programme, pending the outcome of the recent market structure consultation. In practice, this keeps more of the funding burden on gilts rather than bills and partially helps explain why the headline remit number came in slightly higher than expected. It also leaves room for the DMO to revisit bill usage later in the year once the consultation feedback is digested, meaning bills could still play a larger role if market conditions or funding needs shift.

Overall, we see the Spring Statement as broadly gilt positive and with the supply dynamics and the DMO’s flexibility around future issuance, it reinforces our positioning of being long UK duration across our strategies.
