AbstractThis study examines how the Bank of Japan’s (BOJ’s) exchange-traded fund (ETF) and corporate bond (CB) purchases affect the capital structure of Japanese listed firms. The results first suggest that the BOJ’s ETF purchases reduced the equity risk premium for firms included in the purchases, thereby lowering their cost of equity. These firms issued more stocks and became less dependent on bond debt and bank loans than control firms, resulting in a lower level of leverage. On the other hand, the BOJ’s CB purchases lowered the risk premium of bonds eligible for such purchases, which implies a decline in the cost of bond debt. Firms eligible for CB purchases issued more bonds, while reducing bank debt but to a smaller extent, thus having higher leverage than firms not eligible for CB purchases. Categorizing firms into four groups based on whether their stocks were included in ETF purchases and/or their bonds were eligible for CB purchases further shows that the policy impacts on firm financing have differed depending on which group a firm fell in. These results indicate that the BOJ’s ETF and CB purchases have had a considerable impact on the cost of capital, securities issuance activities, and corporate capital structure.
