Abstract
We study how banks manage their liquidity among the various assets at their disposal. We exploit the introduction of the ECB’s two-tier system which heterogeneously reduced the cost of additional reserves holdings. We find that the treated banks increase reserve holdings by borrowing on the interbank market, decreasing lending to affiliates of the same group, and selling marketable securities. We also find that banks have a preference for a stable portfolio composition of liquid assets over time. Our results imply that frictions in one market for liquidity can spill over to several markets.

Abstract
On 30 October 2019 the ECB implemented a two-tier system under which a portion of credit institutions’ excess liquidity holdings with the Eurosystem are exempt from remuneration at negative rates. The aim of the two-tier system is to support the bank-based transmission of monetary policy in preserving the overall positive contribution of negative rates to the accommodative stance of monetary policy. With the introduction of the two-tier system banks holding less excess liquidity than their exemption allowance increased their excess liquidity holdings by borrowing from banks exceeding their exemption allowances. The bulk of banks’ increased borrowing in the money market occurred via secured transactions. Although the increase in trading activity temporarily coincided with higher money market rates, experience with the two-tier system over its first month shows that money market rates were only marginally affected and remain well aligned with the policy rate.

Abstract
Since 2008, excess liquidity – defined as the sum of holdings of central bank reserves in excess of reserve requirements and holdings of equivalent central bank deposits – has tended to accumulate in specific euro area countries and in a small, slowly changing group of credit institutions. Despite the stability of the concentration of excess liquidity in specific countries over time, the relevance of individual drivers has changed. First, risk aversion has played a much smaller role in explaining the concentration since 2013 than it did at the time of “flight-to-quality” phenomena in the period 2010-12. Second, the location of the relevant market infrastructures (i.e. central securities depositories, securities settlement systems and TARGET2 accounts) used by counterparties that sold assets to the Eurosystem has been a more important driver directing flows in the period 2015-16. In addition, the more recent concentration of excess liquidity is explained by the combination of a number of factors, such as banks following strict internal credit limits, investment incentives created by yield differences across the euro area and the “home bias” in euro area government bond holdings. Overall, the net cross-border flows of liquidity that resulted also determined TARGET2 balances. At the individual bank level, when controlling for banks’ capital, non-performing loans, credit risk and profitability, excess liquidity holdings in relation to total assets are found to be higher for smaller and better-capitalised banks, and for banking groups with liquidity centralised at the head institution. In addition, participation in Eurosystem longer-term refinancing operations and deposit inflows are associated with liquidity accumulation. Finally, new regulatory initiatives such as the liquidity coverage ratio are explained to be creating incentives to hold or not to distribute liquidity, thereby affecting its distribution.
