Regulations could led to lower global growth?

This week, we could read in the major newspapers about the G20 new regulatory guidelines of the global financial system and how these will be applied in the United States, United Kingdom and continental Europe.

In Pittburg September 23-24Th, the G20 decided to raise the bank's equity capital level while the bonus of traders and of senior management team will be will be more strictly supervised.

Tuesday October 29Th, Le Monde publish : "G20 : deux banquiers français saluent de « sages » décisions", Anne Michel ( "G20 : Two french banker welcome the wise decisions").
Baudouin Prot, CEO of BNP Paribas, and Frédéric Oudéa, President of Société générale, expressed that on the one hand the leverage ratio has to stay under control to avoid future bankruptcies (Lehman's case & The financial crisis) and on the other hand, the implemtation of international regulations on bonuses and variable incomes was compulsory. French banks have already implemented some of these reforms and will try to apply them fully during the following weeks.
They are pleased to welcome such international decisions but they know that there is still a lot of work to carry out these reforms on the international sceen.

Two days later, the Financial Times publish : "UK banks face tougher bonus curbs than us",K. Guha & P. Jenkins, 01.10.09. "A diver has emerged between Europe and US over how implement new Group of 20 rules on bankers' bonuses..".
As a matter of fact, British government was pleased to announce on Thursday that British five major banks agree to apply the bonus restriction policy of the G20 summit, while Washington tries to explain his reluctance for this new wave of international reforms by a more "balance" view. "The nature of the business involved is so diverse that banks need to be given flexibility to come up with the right package for each type of employee", report the Financial Times.

Today, we could read on Reuters web site (Don't resist reform, G7 policymakers tell banks, Oct 4 2009) as well on the FT web side (Ministers hit back at bankers over regulation, By Krishna Guha, Oct 4 2009) about reluctant bankers during the IMF/World Bank annual meetings in Istanbul.
On the one side, the board of the Institute of International Finance, the global bankers’ association, as well as Josef Ackermann, the IIF chairman and head of Deutsche Bank, warning the world community and politician that these excess of reforms could lead to a lower global growth and less job. On the other side, we have Mario Draghi, governor of the Bank of Italy and head of the Financial Stability Board saying : “I think it is a bit premature to be concerned about the excess of rules at this stage frankly.”.

Honestly, we couldn't say he is wrong. In the past, the financial system and institution were under regulated which cost a lot of money/welfare and created economical insecurity for a year.
