«The most significant thing today was the sharp decline in financial stocks because of the new capital requirements,» said Ruben Pascuali, a trader at Mayoral brokerage. «This partially restricts the payment of dividends. It is clearly bad news for the sector.»
Grupo Financiero Galicia SA (GGAL.BA, GGAL) led the declines, dropping 5.9% to ARS3.54; Banco Frances (FRAN.BA) fell 5.5% to ARS9.59; Banco Patagonia SA (BPAT.BA, BPATL) slid 3.2% to ARS3.61.
The only Merval company to rise was the steel producer Tenaris (TS, TEN.MI), which rose 0.16% to ARS91.90.
Under the new capital requirements, starting Feb. 1, local banks will have to start raising the amount of capital required to guard against unexpected losses to 75% of total capital before distributing dividends, the Central Bank said. The minimum-capital requirement will be equivalent to an average of 15% of gross income over the last three years.
The move will increase the total capitalization requirement for the banking system by about 1.2%, the central bank said. Banks must meet half of the new requirement by February, 75% of it by August and be in full compliance by December.
The Global X FTSE Argentina 20 ETF fell 1.08% to $11.95.
