Handelsaktiviteten faldt i kølvandet på finanskrisen i 2008, hvilket kan afspejle øget opmærksomhed på kreditrisiko og en reduktion i antallet af kreditinstitutter som følge af fusioner og banklukninger. Handelsaktiviteten blev yderligere reduceret efter den store forøgelse af de pengepolitiske modparters rammer for indestående på foliokonti i Nationalbanken i forbindelse med introduktionen af negative renter. I de seneste par år er handelsaktiviteten ble- vet koncentreret omkring relativt få markedsdeltagere, hovedsageligt de systemiske institutter. Analysen er baseret på data for pengemarkedstransaktioner mellem Nationalbankens pengepoliti- ske modparter, som er estimeret på basis af betalinger i Nationalbankens betalingssystem, Kronos for perioden 2003-2015. ABSTRACT The short-term Danish interbank market before, during and after the financial crisis The paper studies the microstructure of the short-term uncollateralised Danish interbank market before, during and after the financial crisis. The financial crisis in 2008 was followed by a slowdown in trading activity which might reflect increased awareness of counterparty credit-risk and a reduc- tion in the number of banks due to mergers and acquisitions as well as bank failures. A further re- duction in trading activity followed the large increase of the monetary-policy counterparties' cur- rent-account limits in mid-2012 in relation to introduction of negative interest rates. In the most recent years, the trading activity has been concentrated on relatively few participants, mainly the Systemically Important Financial Institutions (SIFIs). The analysis is based on data on money- market transactions among Danmarks Nationalbank's monetary-policy counterparties estimated from payment flows from Danmarks Nationalbank's payment system, Kronos, for the period 2003- 2015. 4 KEY WORDS Interbank market structures; Day-to-day interest rates; Payment system data; Monetary-policy im- plementation; Interconnectedness.

More specifically, we focus on Danmarks Nationalbank's mone- tary-policy counterparties' trading among themselves in the market for uncollateralised krone- denominated loan contracts with a maturity of one day. We pay particular attention to the inter- play between the money market and the Nationalbank's monetary-policy instruments. Further- more, we address the interconnectedness of the market participants from a financial stability per- spective. The analysis is based on data on money-market transactions among Danmarks National- bank's monetary-policy counterparties estimated from payment flows from Danmarks National- bank's payment system, Kronos, for the period 2003-2015. During the last couple of years the total daily turnover of uncollateralised day-to-day loans among Danmarks Nationalbank's monetary-policy counterparties has amounted to around 4,000- 5,000 million kroner per banking day. There has been a downward trend in trading activity – both in turnover volumes and the number of transactions – since the outbreak of the most recent finan- cial crisis in 2008. This might reflect increased awareness of counterparty credit-risk and therefore a switch towards a higher degree of collateralised lending which also has been seen in the euro area money market. There has been a further reduction in trading activity since the significant in- crease of the counterparties' current-account limits in mid-2012 in relation to the introduction of negative interest rates on Danmarks Nationalbank's certificates of deposit. The current-account rate remained unchanged at zero per cent which all else equal gave the counterparties an incen- tive to place funds at current accounts rather than in certificates of deposit or placements in the interbank market. Furthermore, the higher current-account deposits enabled the banks to manage large daily liquidity fluctuations without resorting to the interbank market. The overnight 1 segment has on average been slightly larger than the tomorrow-next 2 segment when it comes to trading volume among the Nationalbank's monetary-policy counterparties. Measured by the share of transactions, however, the overnight segment is much larger than the tomorrow-next segment. This probably reflects that tomorrow-next trades are planned in advance, while overnight trades
