Mae chwe blynedd wedi bod bellach ers cyflwyno Deddf Cyllid y Gwasanaeth Iechyd Gwladol 2014 a'r ddyletswydd i fantoli'r gyllideb dros dair blynedd. Yn y ddwy flynedd diwethaf yn enwedig, mae gwelliant cyson wedi bod yn y perfformiad ariannol cyffredinol a nifer y cyrff sydd nawr wedi mantoli'r gyllideb. Serch hynny, mae'r pedwar corff nad ydynt wedi gallu gweithio o fewn eu cyllidebau dros y cyfnod hwn wedi cronni diffygion o dros £600 miliwn yn gyfan gwbl ers 2014. Yn ogystal, mae Llywodraeth Cymru wedi gorfod darparu cyfanswm o bron i £470 miliwn o gymorth ariannol strategol i'r cyrff hyn i'w galluogi i gyflawni eu rhwymedigaethau ariannol i staff a chyflenwyr tra maent mewn diffyg.
It is now six years since the implementation of the NHS Finance Act 2014 and the introduction of the three year break even duty. The last two years in particular have seen a sustained improvement in overall financial performance and the number of organisations now in financial balance. However, the four organisations that have been unable to operate within their budgets over this period have accumulated deficits totalling over £600 million since 2014. In addition, Welsh Government has had to provide strategic cash support totalling nearly £470 million to these organisations to enable them to meet their financial obligations to staff and suppliers whilst in deficit.
