The effect of regulations on the banking sector is a key question for financial intermediation. This paper provides evidence that merger control regulation, although not directly targeted at the banking sector, has substantial economic effects on bank mergers. Based on an extensive sample of European countries, we show that target announcement premia increased by up to 16 percentage points for mergers involving control shifts after changes in merger legislation, consistent with a market expectation of increased profitability. These effects go hand-in-hand with a reduction in the propensity for mergers to create banks that are too-big-to-fail in their country.
We find that stricter merger control legislation increases abnormal announcement returns of targets in bank mergers by 7 percentage points. Analyzing potential explanations for this result, we document an increase in the pre-merger profitability of targets, a decrease in the size of acquirers, and a decreasing share of transactions in which banks are acquired by other banks. Other merger properties, including the size and risk profile of targets, the geographic overlap of merging banks, and the stock market response of rivals appear unaffected. The evidence suggests that the strengthening of merger control leads to more efficient and more competitive transactions.
