PurposeThis study seeks to analyse if the adjustment towards the target short-term debt ratio of small and medium-sized firms (SMEs) is related to financial distress risk.Design/methodology/approachData obtained for a sample of Portuguese manufacturing SMEs from 2010 to 2017 were analysed using the system-generalised method of moments (GMM-sys). Using the modified Z-Altman score, the authors classify SMEs according to their exposure to financial distress risk.FindingsManufacturing SMEs exposed to a high risk of financial distress rebalance their short-term debt ratio quicker. However, regardless of the financial distress risk level, SMEs distant from the target short-term debt ratio adjust more slowly, suggesting that transaction costs are greater than financial distress costs.Practical implicationsPolicymakers should promote the access to external sources of finance with low transaction costs for SMEs, exposed to low levels of financial distress risk, to rebalance their short-term debt ratios quicker. Distressed SMEs far from their target short-term debt ratios, but with capacity to rebalance, need government programmes to access finance with low transaction costs to rebalance their short-term debt ratios.Originality/valueThis paper contributes to deepening our understanding of how SMEs, facing financial risk, rebalance their short-term debt ratios. SMEs, facing high financial distress risk, adjust towards their target short-term debt ratios more rapidly. However, SMEs, distant from the target short-term debt ratio face higher transaction costs than financial distress costs. These firms adjust towards their target short-term debt ratios more slowly, which may aggravate the refinancing risk and, ultimately, announce bankruptcy.
