The group will decide whether the headquarters should be in Shanghai or New Delhi, Russian Finance Minister Anton Siluanov said on Wednesday.
The creation by Brazil, Russia, India, China and South Africa of a 100 billion dollar bank to finance infrastructure projects has been slow in coming, with disagreements over its funding, management and headquarters.
"The (headquarters) issue will be decided on the level of the heads of the countries," Siluanov told journalists, adding that the choice is between China's Shanghai and India's New Delhi. BRICS leaders will meet July 15-16 in the Brazilian coastal city of Fortaleza.
The launch of the bank will be the group's first major achievement after struggling to take coordinated action following an exodus of capital from emerging markets last year, triggered by the scaling back of US monetary stimulus.
The new bank will symbolize the growing influence of the BRICS, something that Russia has hoped for after the West imposed sanctions on Moscow in the spring for annexing part of
Ukraine and its continued involvement in the country's crisis.
Capitalisation of the new bank has been a major sticking point, but Siluanov confirmed that the funding would be divided equally, with an initial total of 10 billion dollars in cash over seven years and 40 billion dollars in guarantees.
The 50 billion dollars will be eventually built up to 100 billion dollars, and the bank will be able to start lending in 2016, he said.
The bank was first proposed in 2012. The proposal was approved last year at a BRICS summit in South Africa but failed to be launched during the meeting in Russia last autumn of the Group of 20 developed and developing nations.
The bank will be open to other countries that are United Nations members, but the BRICS share is never to decline below 55 per cent, Siluanov said.
The chairmanship, with a term of five years, will rotate among the members, but the first chairmanship is yet to be decided, Siluanov said.
FRAMEWORK AGREEMENT ON CURRENCY POOL
The heads of the BRICS will also sign a blueprint agreement on the group's other project - a 100 billion dollar fund to steady the currency markets, which has also been off to a slow start.
The initiative became more acutely needed after an inflow of cheap dollars fuelled a boom in the BRICS for a decade and then reversed to a sharp outflow last year.
"We have reached an agreement that, in current conditions of capital volatility, it is important for our countries to have this buffer in addition to the International Monetary Fund," Siluanov said.
But the framework agreement to be signed in Brazil will not include any direct commitments, which are due to come later when the central banks sign agreements.
A senior Brazilian official who participates in the negotiations said the pool could become operational as soon as in 2015.
According to the agreement, the cash will continue to be held in the reserves of each BRICS country, but it can be transferred if needed to another member to soften volatility in its foreign exchange market.
China, holder of the world's largest foreign exchange reserves, will contribute the bulk of the contingency currency pool, or 41 billion dollars.
Brazil, India and Russia will chip in 18 billion dollars each and South Africa 5 billion dollars.
"It is to be a mechanism that could react swiftly to capital outflow by offering swap operations in dollars," Siluanov said.
If a need arises, China will be eligible to ask for half of its contribution, South Africa for double and the remaining countries the amount they put in.
"Some countries may put in less, but their needs are also greater, proportionally," Siluanov said.
A BRICS member would be able to immediately get 30 per cent of its eligible share and the remaining 70 per cent only with a stabilisation programme from the IMF, Siluanov said.
