EXPLAINER -Why is Germany's budget in crisis and what are the implications?

(Updates item first published earlier in November)

BERLIN, Nov 22 (Reuters) - Germany's constitutional court ruled last week that the coalition government's decision to reallocate 60 billion euros ($65.21 billion) of unused debt from the pandemic era to its climate and transformation fund (CTF) was unconstitutional.

The ruling, however, potentially also affects other off-budget funds that the country has used over the years to finance government policy in order to comply with its self-imposed debt brake restricting the public deficit to 0.35% of GDP.

Here are some of the implications for the budget, the economy, German fiscal policy and Chancellor Olaf Scholz's three-way coalition:

WHAT COMES NEXT FOR THE 2024 BUDGET?

The ruling did not directly impact the regular 2024 budget, which is due to be voted on by parliament on Dec. 1.

Still, it means there is a funding gap for projects that were due to be covered by the CTF and other funds that may be affected by the ruling - both this year and next.

If you consider, for example, that the annulled CTF funds were due to be spent by 2027 that implies a gap in funding of about 10-20 billion euros per year, according to Scope Ratings.

As such, Scholz's coalition of his Social Democrats (SPD), the Greens and the Free Democrats (FDP) could end up making alterations to next year's budget, currently amounting to 446 billion euros.

The government looks set to postpone talks planned for Thursday on the 2024 budget as it struggles to figure out solutions.

Some politicians from the fiscally hawkish FDP have argued in favour of cutting some social expenditure - a move to which the centre-left SPD and Greens object.

The government currently looks likely to suspend its debt brake for 2023, five government sources told Reuters. That however does not necessarily account for the funding gap next year and it is unclear if the government might suspend the brake again.

Germany can suspend the debt brake if it is hit by a natural disaster or "exceptional emergencies" that are beyond the control of the state and significantly affect its finances. The question is whether the current circumstances can be considered an "exceptional emergency" - and whether or not the FDP agrees to a suspension.

WHAT PROJECTS ARE IN JEOPARDY?

The government has been relying on the CTF to finance much of its agenda to support industry, keep it competitive and transition towards a carbon neutral economy.

German industrial projects in jeopardy from the blow to the CTF include chip factories, decarbonised steel production and expansion of the battery supply chain, according to government sources.
