Debt beat the forecast, borrowing missed it

The ONS put net debt at 94.1% of GDP on 21 August, 0.3 points below the OBR profile, and reported borrowing £2.3bn above that same profile in the same bulletin.

Key takeaway

One bulletin beat the OBR forecast on debt and missed it on borrowing.

The Office for National Statistics (ONS) put public sector net debt at £2,984.9bn at the end of July 2026, equal to 94.1% of gross domestic product (GDP), in the monthly public finances bulletin it published on 21 August 1. Net debt on that measure is what the state owes to the UK private sector and to overseas holders, less the liquid assets it could call on. That ratio sits 0.8 percentage points lower than a year earlier and 0.3 points below the profile set by the Office for Budget Responsibility (OBR), the government's independent forecaster. GDP is the value of everything the economy produces in a year, so 94.1% means the state owes a little less than the country makes in twelve months.

Borrowing in July came to £1.8bn, which is £2.3bn above the OBR profile, and borrowing in the financial year to July stands at £56.7bn, £6.0bn (9.6%) below the same period last year and again £2.3bn above the profile 2. The same bulletin therefore reports the opposite result on the other measure. The overshoot is larger than the borrowing itself, and the whole of the financial year's miss arrived in one month rather than building across four. Neither comparison belongs to this desk: the ONS states both against the OBR's numbers, in one document, on one day.

Debt is £95.9bn higher in cash than a year earlier while the ratio is lower. The ONS says its updated estimate of January to March output came in above the first estimate, "resulting in lower debt-to-GDP ratios for recent months than previously reported" 3, and it puts no number on that effect. The share of the economy fell because the economy was re-measured, not because the borrowing stopped.

The forecast beaten on one line and missed on the other was published on 3 March 2026, with the monthly profiles the ONS scores against following in April, and the OBR does not refresh any of it until the Budget on 28 October . Debt interest payable by central government ran to £7.7bn in July alone, against £7.0bn in July 2025, and that bill is settled before a single bin is emptied or a single appointment is booked. This desk's June cell of 94.9% cannot be set beside 94.1%, because the ONS did not restate the June ratio on the new output base and published no replacement for it.

Deep Analysis

In plain English

The government keeps a running total of everything it owes, called public sector net debt. To judge whether that total is manageable, it is usually shown as a share of GDP, the size of the whole economy in a year, because a bigger economy can carry a bigger debt without strain. In July, that share came in at 94.1%, a little better than the official forecaster expected. But in the same report, the amount the government actually borrowed that month came in worse than expected. Both things are true at once because they come from different parts of the sum: the economy was recently measured as slightly bigger than first thought, which makes the debt look smaller by comparison, even though the pounds borrowed did not fall.

Deep Analysis
Root Causes

The ratio moved because its denominator moved, not because its numerator did. ONS incorporated the Q2 GDP first estimate, published 13 August, eight days before this bulletin, which revised earlier-quarter output upward; every debt-to-GDP figure for those quarters is recalculated against the new base the moment it lands, independent of anything the government spent or borrowed.

A second structural cause sits in the fiscal calendar itself. The OBR sets one forecast per fiscal event and profiles it monthly without interim revision, so every ONS bulletin between March and October is scored against a static baseline that cannot absorb news the baseline itself has not yet seen. That gap is what lets a single bulletin beat the forecast on one measure and miss it on another without contradiction.

What could happen next?
  • Meaning

    The debt-ratio improvement reflects a bigger measured economy, not reduced government borrowing.

    Immediate · Assessed
  • Precedent

    Both this reading and June's upward revision came from data updates rather than fiscal decisions, suggesting monthly moves in the ratio should be read cautiously until the OBR rebases its forecast.

    Short term · Suggested
  • Risk

    The £2.3bn borrowing overshoot against the OBR profile, if it persists monthly, would compound toward the October Budget without a forecast update to register it until then.

Debt beat the forecast, borrowing missed it
Britain's position is being scored against a forecast written on 3 March that does not refresh until the Budget on 28 October.
Different Perspectives
Structural case for reading the fall as genuine improvement

The debt ratio fell, borrowing fell year-on-year in cash terms by £6.0bn over the financial year to date, and two gilt auctions cleared at bid-to-cover ratios of 3.39 and 3.58 times with no sign of buyers demanding a premium for risk. On that reading, the state of Britain's public finances has not deteriorated this fortnight.

The OBR's Economic and Fiscal Outlook, the forecast the ONS bulletin was checked against, dates to 3 March 2026 and will not be updated until 28 October, with no change made in this window to the 1.4% long-run productivity assumption that most moves its debt projections. It made no comment on this fortnight's releases directly.
