The ECB's quarterly projections, set to be to presented to its Governing Council on Wednesday, will put inflation north of 3% in 2024, the source said, confounding expectations for a small cut.
The updated 2024 projection is well above the central bank's 2% target and will be higher than the 3% forecast in June.
The source said the rate decision was still a close call and formal proposals for the meeting have not yet been presented.
But both headline and underlying inflation remain above 5%, raising the risk that workers will start demanding bigger pay increases, especially because the labour market remains exceptionally tight.
Growth on the other hand will be downgraded for this year and 2024, roughly in line with market expectations, the source said.
