To be effective, any tax on financial transactions would have to be implemented on a global scale, which currently does not seem realistic. Moreover, taxation would increase costs (passed on to borrowers) and reduce the volume of transactions, thereby fueling market volatility amid decreasing liquidity.
为确保有效性，对金融交易的征税必须在全球范围内实施，而这在目前似乎是不切实际的。另外，税收会增加成本（转嫁给借款人）并减少交易量，从而在流动性降低的同时增加市场的不稳定性。
