The stabilizing expenditure rule (SER) in Poland has been instrumental in fostering fiscal discipline in the years leading up to the pandemic. The pandemic and subsequent shocks severely tested the expenditure rule. Returning to the SER limit after severe shocks proved challenging, making clear the needs to revise the SER to preserve its credibility. The government could enhance the credibility of the expenditure rule through broadening its coverage and strengthening compliance, including establishing an independent fiscal council. Moreover, aligning to the EU fiscal framework will require (i) ensuring expenditure limits implied in the SER to be consistent with the EU net expenditure path; and (ii) providing explanation on the differences in expenditure coverage and classification between the SER and the EU fiscal framework to ensure compliance. Over time, transition to binding multi-year limits in the SER would improve linkages between annual budgets and medium-term fiscal planning.
