This paper investigates the impact of international swap lines on stock returns using data from banks in emerging markets. The analysis shows that swap lines by the Swiss National Bank (SNB) had a positive impact on bank stocks in Central and Eastern Europe. It then highlights the importance of individual bank characteristics in identifying the impact of swap lines on bank stocks. Bank-level evidence suggests that stock prices of local and less-well capitalized banks responded strongly to SNB swap lines. This new evidence is consistent with the view that swap lines not only enhanced market liquidity but also reduced risks associated with micro-prudential issues.
