Empréstimo de ações e Juros sobre Capital Próprio: os desdobramentos da Lei no 13.043/2014

Abstract

The purpose of the study was to surveyed the effects of Law no 13.043/2014 on the stock market which made impossible the "barriga de aluguel" strategy. This Law imposed a income tax for the stock borrowing for all takers. The hypothesis is that the funds’s tax arbitrage strategy that retained 15% of the Interest of Own Capital (JCP) due the condition relief’s tax was a short selling’s restriction. So, after the Law, the stock lending will only be used for the short selling. The investors will be benefiting regarding the lending rates’s reduction and the increase of available stocks for trading. We used the market data from the companies listed in B3 of 2014 and 2015 to estimate the law’s mean-effect by Differences in Differences with robust least squares regression. The study database was constructed from public access data and it is not possible to consider only the funds’s negotiations. Even under this restriction the results indicate that the law’s mean-effect was significant because the lending-rates was reducted and lending-volumes was increased in 2015 for the stocks that paied JCP in 2014. The regressions’s results suggest that Law no 13.043/2014 had positive effects on the stock lending market due the reduction in lending-rates reflected in the increase in trading volumes. Otherwise the mean-effect of the new tax may have been underestimated because it included all negotiations and not just investment funds. The contribution of the study was to analyze the mean-effect of IR on stocks lendings that paid JCP in 2014, through a database built from public access information, under a tax prism of the stock lending.
