Abstract: The aim of this paper is to investigate the impact of financial transaction tax (FTT) on the stability of financial market. The paper presents an agent-based financial market model and simulations, in which agents follow technical and fundamental trading rules to determine their speculative investment positions. The model developed by Westerhoff (2009) was chosen for the implementation and it was extended by FTT and arising transaction costs. As FTT may be defined variously, assets are understood as a tax object in this paper. The model includes direct interactions between speculators due to which they may decide to change their trading behaviour and deals with a technical and fundamental strategy of market participants. Results suggest that the modified model has a tendency to stabilize itself in a long-term if the fundamental trading rules overbear the technical trading method. This could be used, when the bubbles and the crashes occur in a financial market. Assets price would be stabilized, because its value targets near the fundamental value and the volatility would be also minimized. Substantial is setting the FTT at a low rate for market stabilization. If FTT and consequent transaction costs are too high, the financial system destabilizes and the price grows without limit.
