"The Swedish experiences were negative, both from the point of view of the state's finances and from a general socioeconomic perspective," former finance minister Bo Lundgren, 64, told AFP.
In 1984, the Social Democratic government introduced a tax of 0.5 percent on each purchase or sale of shares (a level that was doubled two years later) and 1.0 percent on options. The tax on bonds varied depending on the maturity, ranging from 0.03 to 0.001 percent.
The tax was levied on brokerage services.
The Swedish government later introduced a tax on currency transactions in 1989.
But the consequences of both taxes were considered so harmful to the markets that they were soon abolished: the one on currency transactions was removed after just 16 months, in 1990, and the other was removed after eight years, in 1991.
Lundgren, who had the tax on shares, options and bonds abolished when he was finance minister in a centre-right government, told AFP the effects of the currency transaction tax "were so dramatically negative that all currency trading basically moved from Stockholm to London, so the Social Democratic government (in power at the time) abolished the tax."
Meanwhile, the tax on shares, bonds and options "led to share trading moving abroad but the effects were not as dramatic as the currency transaction tax."
"The year we abolished it, in 1991, the tax revenue amounted to around three billion kronor", or about 375 million euros ($476 million) in today's currency.
"But on the other hand the tax had reduced share trades so much that once it was abolished, trading increased and that in turn led to an increase in brokerage fees which led to an increase in corporate tax (revenues) and other tax (revenues) increased."
"When the tax was abolished we estimated that there was no loss (of revenue) involved, because it led to such a sharp increase in trading."
In his proposal to parliament repealing the tax on shares, options and bonds, Lundgren said at the time that "activity on the Swedish stock market has decreased sharply in recent years which has resulted in a series of disadvantages for Swedish industry."
"The tax on shares and other securities has contributed to this development," he said.
He said Swedish companies suffered from reduced liquidity on the stock market and had a harder time raising risk capital.
Lundgren, who is now the head of Sweden's National Debt Office, and Sweden's current Finance Minister Anders Borg -- both members of the conservative Moderate party -- have voiced opposition to the European Commission's proposal to tax financial transactions.
The Commission in September proposed a tax of 0.1 percent on stock and bond transactions and 0.01 percent on derivatives, aimed at pulling in up to 55 billion euros ($70.4 billion) annually.
France and Germany are in favour of the tax and have said the 17-member eurozone could adopt it on its own, while non-euro member Britain is fiercely opposed to it amid fears it could prove devastating to its global financial hub, the City of London.
Paris has gone so far as to say it could begin introducing the tax on its own if a broader agreement is not reached.
