Abstract: Prior to the recent global financial crisis, one of the most prominent examples of unconventional monetary stimulus was Japan's “quantitative easing policy” (QEP). Most analysts agree that the QEP did not succeed in stimulating aggregate demand sufficiently to overcome persistent deflation. However, it remains unclear whether the QEP simply provided little stimulus, or whether its positive effects were overwhelmed by the contractionary forces in Japan's post-bubble economy. In the spirit of Kashyap and Stein (2000) and Hosono (2006), this paper uses bank-level data from 2000 to 2009 to examine the effectiveness in promoting bank lending of a key element of the QEP, the Bank of Japan's injections of liquidity into the interbank market. We identify a robust, positive, and statistically significant effect of bank liquidity positions on lending, especially for weaker banks, suggesting that the expansion of reserves associated with the QEP boosted the flow of credit. However, the overall size of that boost was probably quite small. First, the estimated response of lending to liquidity positions in our regressions is small. Second, although the BOJ's reserve injections boosted bank liquidity significantly, much of the effect was offset as banks reduced their lending to each other. Finally, the effect of liquidity on lending appears to have held only during the initial years of the QEP, when the banking system was at its weakest; by 2005, even before the QEP was abandoned, the relationship between liquidity and lending had evaporated.
