Mexico should be up in arms against China and its weak renminbi.

Sir Arvind Subramanian, based on Dani Rodrik’s estimates, makes a solid case for how “It is the poor [emerging countries] who pay for the weak renminbi” February 4. The argument gets to be even clearer if using specific examples.

Mexico, should be USA’s China, had it not been for the fact that China’s political system makes it so much easier to manage a weak renminbi than Mexico’s a weak Mexican peso.

They have not even imagined how right they are

Sir having for more than thirty years argued about the dangers for the bathtubs of a small economies to lie completely open next to the global financial oceans exposed to their tsunamis I could not but fully agree with the general direction of Dani Rodrik’s and Arvind Subramanian’s “Why we need to curb global flows of capital” February 26.

Having said that I would much rather use the term “slow” than “curb” because it is the speed of how the financial resources move that causes the most damages.

But let me put forward a much more important comment. When the authors say that one should not be “too optimistic about the potential of prudential regulation to stem excessive risk-taking” they are more right than they have imagined in their wildest dreams or wildest hypothesis. In fact, it was precisely the running away from the risks, forced upon the financial market by the regulators through their minimum capital requirements for the banks and that was based exclusively on risk-assessments carried out by the regulator’s own outsourced risk overseers, the credit rating agencies that set us up to all what is currently happening.
