economy, as the nineties' crises in Mexico, Southeast Asia and Russia have proven. My tax would return some margin of manoeuvre to issuing banks in small countries and would be a measure of opposition to the dictate of the financial markets. Though James Tobin suggested the rate as "let's say 0.5%", in that interview setting, others have tried to be more precise in their search for the optimum rate. Economic literature of the period 1990s-2000s emphasized that variations in the terms of payment in trade-related transactions (so-called "swaps" for instance) provided a ready means of evading a tax levied on currency only. Accordingly, most debate on the issue has shifted towards a general financial transaction tax which would capture such proxies. Other measures to avoid punishing hedging (a form of insurance for cashflows) were also proposed. By the 2010s the Basel II and Basel III frameworks required reporting that would help to differentiate them and economic thought was tending to reject the belief that they could not be differentiated, or (as the "Chicago School" had held) should not be. Recent proposals In March 2016 China drafted rules to impose a genuine currency transaction tax and this was referred to in financial press as a Tobin tax . This was widely viewed as a warning to curb shorting of its currency the yuan. It was however expected to keep this tax at 0% initially, calculating potential revenue from different rate schemes and exemptions, and not to impose the actual tax unless speculation increased. Also in 2016 US Democratic Party POTUS nominee Hillary Clinton included in her platform a vow to "Impose a tax on high-frequency trading. The growth of high-frequency trading has unnecessarily placed stress on our markets, created instability, and enabled unfair and abusive trading strategies. Hillary would impose a tax on harmful high-frequency trading and reform rules to make our stock markets fairer, more open, and transparent.". However, the term "high-frequency" implied that only a few large volume transaction players engaged in arbitrage would likely be affected. Clinton referred separately to "Impose a risk fee on the largest financial institutions. Big banks and financial companies would be required to pay a fee based on their size and their risk of contributing to another crisis." The calculations of such fees would necessarily depend on financial risk management criteria (see Basel II and Basel III). Because of its restriction to so-called
