LONDON, Nov 26 (Reuters) - The pound briefly jumped to session highs, while UK government bond prices staged a short, sharp rise on Wednesday, after the independent Office for Budget Responsibility released its forecasts early, offering a more upbeat view of Britain's economy and finances.

Britain's government will have almost 22 billion pounds ($28.9 billion) in fiscal headroom in five years' time, according to estimates by the country's budget watchdog published on its website on Wednesday ahead of finance minister Rachel Reeves' budget statement. That is higher than a Reuters poll expected.

COMMENTS:

NEIL WILSON, UK INVESTOR STRATEGIST, SAXO MARKETS, LONDON:

"Here is the key to why markets might see this budget as lacking credibility - the direct effects of budget policies increase borrowing by 6 billion pounds next year but reduce it by 15 billion pounds in 2029-30.

"The indirect effects of budget policy measures on the economy are estimated to lower borrowing by 2 billion pounds in 2026-27 largely thanks to impact of lower inflation on debt interest spending. From 2027-28 onwards, the indirect effects of policy add to borrowing by amounts rising to 5 billion pounds in 2029-30.

"This was one of our key questions this morning - How are you selling fiscal restraint at the end of the parliament when you have signally failed to deliver any cuts or reform to welfare spending?

"Fiscal buffer increases to 21.7 billion pounds from 9.9 billion as a result - but who cares about the buffer if the assumptions are not credible?"

KALLUM PICKERING, CHIEF ECONOMIST, PEEL HUNT, LONDON:

"10-year gilt yields are up slightly, inflation expectations are up a bit too and not much change for Bank of England pricing, to a large extent it doesn’t seem to be surprising markets much.

"My concerns are that the headroom - although it looks bigger, 22 billion pounds versus the current spending of 9.9 billion pounds - when I look at the composition a lot of it is backloaded.

"You go pretty aggressive from 2026 onwards into a current surplus, which means the market is being asked to believe the OBR forecast which is chronically optimistic, which is why I think the market is a bit concerned."

PHILIP SHAW, CHIEF ECONOMIST, INVESTEC, LONDON:

"This timing of headlines is a big surprise, but at first glance they seem relatively favourable in terms of the fiscal metrics."

"Over the budget process, you would expect the Chancellor to unveil the measures and the OBR arithmetic gradually when she stands up and the OBR numbers to be revealed when she sits down again.

"Number one: this is early and secondly from what we can see at the moment, the fiscal numbers look relatively benign, with the government on track to meet its fiscal rules more comfortably than expected."

ANDREW WISHART, SENIOR UK ECONOMIST, BERENBERG, LONDON:

"It's not clear if this (the OBR release) is a mistake or not, but so far so good in terms of the headline numbers."

"The headroom has increased and more importantly we can see a tightening in the budget deficit over the next two years and that supports the argument for BOE rate cuts."

JEREMY STRETCH, HEAD OF G10 FX STRATEGY, CIBC CAPITAL MARKETS, LONDON:

"If the headlines are correct in terms of greater fiscal room that is beneficial for gilts. The downside is that if fiscal headroom is larger it could mean that we get more fiscal tightening.

"So we have part of the story, but there are questions to be asked."

"Trend growth has been revised down compared to the spring and that's not great from a productivity perspective."
