  • We study the microstructure of the short-term uncollateralised Danish interbank market.
  • The analysis is based on payment flows from Danmarks Nationalbank's RTGS system 2003-2015.
  • Trading activity has declined after the financial crisis and the move to negative interest rates.
  • With ample central bank liquidity, activity has recently concentrated on few participants.

Denmark  was the first country to move its key monetary policy interest rate into negative territory, in early July 2012. This paper studies the microstructure of the short-term uncollateralized Danish interbank market before, during and after the financial crisis, and into an era of negative interest rates. The 2008 financial  crisis was followed by a downturn  in trading activity, which may reflect increased awareness of counterparty credit risk at this time, or a reduction  in the number of banks due to mergers/acquisitions and bank failures. A further reduction in trading activity followed in mid-2012, with a large increase in the current account liquidity maintained by monetary policy counterparties  when interest rates became negative. In recent years, trading activity has concentrated on relatively  few participants, mainly the so-called systemically important financial institutions. Our analysis is based on data from money market transactions between Danmarks Nationalbank’s monetary policy counterparties, estimated from payment flows through Danmarks Nationalbank’s real-time gross settlement system for the period 2003–15. Our data has been carefully validated against other data sources.
