Financial Network Analyzer update

By Kimmo Soramäki | Published: February 23, 2011
As many of you know, Financial Network Analyzer is the program that I have been developing for the past year and a half. Its currently mainly used by central banks for the analysis of financial microdata and for the simulation of payment systems. After major rewrite of much of the application and thorough testing, FNA 1.3 [...]

Systemically important banks get better terms for their overnight borrowing

By Kimmo Soramäki | Published: July 2, 2010
A new paper by Farooq Akram and Casper Christophersen entitled “Interbank overnight interest rates – gains from systemic importance” analyses the Norwegian overnight interbank interest rates paid by banks. They find that during the Financial crisis, the interest rates were substantially below indicative quotes of interest rates provided by major banks. The interest rate variation [...]

Receipt reactive gross settlement simulator

By Kimmo Soramäki | Published: September 13, 2009
The Receipt Reactive Gross Settlement (RRGS) method was proposed by Jamie McAndrews in Johnson-McAndrews and Soramaki (2004) as a new, incentive compatible liquidity saving mechanism. The basic idea of RRGS is that banks are sure to use only incoming funds to settle their less urgent payments. Each bank has the incentive to submit payments to [...]

Software for identifying interbank loans from payment data

By Kimmo Soramäki | Published: August 21, 2009
In 1999 Craig Furfine published the article “Interbank exposures: quantifying the risk of contagion” (BIS Working paper, No. 70) where he for the first time used data on individual payments settled in the interbank payment system to construct a time series of the unsecured overnight loan market. The methodology has since been duplicated by numerous [...]

Genetic algorithms in Java

By Kimmo Soramäki | Published: March 26, 2009
As part of another project I revisited some Java code for developing genetic algorithms (GA). I had programmed them earlier as part of our Agent-based simulations where banks’ decision making evolved through the use of genetic algorithms. I decided to make the general purpose GA code available in case someone finds a use for it. [...]
