Cynigiodd y Gweinidogion Cyllid, fel rhan o’r Adolygiad o Wariant, y dylid diweddaru’r trefniadau cyllidol rhynglywodraethol. Diweddarwyd y Datganiad Polisi Ariannu ddiwethaf yn 2010; mae newidiadau polisi sylweddol wedi bod ers hynny, gan gynnwys datganoli trethi a phwerau benthyca.
The Finance Ministers proposed that, as part of the Spending Review, the inter-governmental fiscal arrangements should be updated. The Statement of Funding Policy was last updated in 2010, and significant policy changes have happened since then, including devolution of taxes and borrowing powers.
