Spain is due to set out its austerity budget for 2013 later, against a backdrop of a deteriorating economy and 25% unemployment rate.
Madrid is expected to outline 39bn euros ($50bn; Â£31bn) worth of savings, tax rises, and structural reforms.
It comes amid further protests this week, and growing expectations that Spain will seek a bailout from its eurozone partners.
On Friday, results of a stress test on Spain’s banks are due to be released.
Meanwhile Castile La Mancha has become the fifth of Spain’s 17 regional governments to say that it will draw on a rescue fund set up by Madrid.
The central Spanish region said it would request 848m euros from the 18bn-euro Regional Liquidity Fund, joining Valencia, Murcia and Catalonia, who have collectively requested 3bn euros, and Andalucia who has yet to specify how much it needs.
