Summary

In this comment were estimated the net benefits of Basel III

implementation for a diverse sample of developing economies:
Brazil, Mexico;
China, India;
Nigeria, South Africa;
Russia, Ukraine.

The main aim of the study is to examine the long-term effect on GDP growth.

Basel III – A Quick Primer

The goal of the proposed Basel

III reforms is to strengthen both microprudential regulations (by increasing the stability of individual banking institutions)
and macroprudential regulations (by reducing systemic risks).

Methodology Overview

The methodology considers the long-term effects on GDP because:
there are

data constraints in calculating the short-term costs;
national regulations are still not in line with Basel III requirements;
bank data on risk-weighted assets and liquidity ratios are under Basel II calculations;

Costs of Basel III
how higher capital ratios affects bank lending spreads;
translating the increase in bank lending spreads into an impact on GDP.

Benefits of Basel III
more stringent regulations reduce the probability and severity of future financial crises

Слайд 5

Minor Benefit for a Majority of Countries

the higher the existing capital

levels, the smaller the net benefits from increased capital.

these results lead to

two observations:
the increases in lending spreads are mostly similar for countries in a given region, except Latin America;
the highest calculated lending spread increases are in Brazil, Russia and Ukraine.
