Economic policy uncertainty and other determinants of corporate cash holdings of Australian energy companies

This study aims to investigate a new determinant of corporate cash holdings of Australian energy firms: economic policy uncertainty (EPU). Based on two motives for holding cash: precautionary and speculative motives, the authors argue that EPU increases financing constraints or induces firms to postpone investment projects, thereby increasing their cash holdings. The authors examine whether the Australian policy-related economic uncertainty affects cash holdings of Australian energy companies.

This research uses a data set of Australian energy firms from 2010 to 2020 and the Australian EPU index, which measures the uncertainty in economic policy, using news coverage of eight major Australian newspapers. To address the potential endogeneity bias and ensure the robustness of the results, three models are used: ordinary least squares, fixed-effects and dynamic generalized method of moments.

The authors find that the EPU index has a significant and positive effect on cash holdings, after controlling for firm-specific factors. While firm size and dividend payments have mixed and insignificant effects, other determinants are significant, such as growth opportunities, net working capital, cash flow, cash flow risk, leverage and capital expenditure. The authors also find that the positive effect of EPU on cash holdings is not the manifestation of EPU affecting corporate investments but rather explained by financing constraints.

The findings have implications for policymakers and regulators in Australia as the uncertainty of their economic policies plays an important role when Australian energy companies determine their cash holding level to manage liquidity risks.

This study is the first to document EPU index as the new determinant of corporate cash holdings of Australian energy companies. Firms in this sector have a great need of funding and liquidity for their operations and capital-intensive projects. High EPU index induces them to hold more cash to avoid liquidity shocks.
