The deal is meant to pump needed liquidity into Antwerp's $50-60 billion, debt-dependent trade, by getting banks to take diamonds, not just receivables, as lending insurance.
With little appetite to buy diamonds in the downturn, Antwerp's more than 1,800 registered diamond traders have been selling at losses, and sometimes have not been getting paid on time or at all, leaving them scarce collateral to borrow funds.
"Additional funds will benefit all stakeholders of the diamond sector -- diamond dealers, banks and mining companies -- and will restore the confidence in the diamond trade," said Freddy J. Hanard, Chief Executive of the AWDC in its statement.
Antwerp's import and export volumes of polished diamonds have plunged 32 percent and 28 percent, respectively, in January to April compared to 2008. Import and export volumes of rough diamonds have dropped 45 percent and 30 percent, respectively.
An AWDC official said the drops have been even more severe in other diamond markets.
Dutch state-controlled bank ABN Amro, the Antwerp Diamond Bank, the State Bank of India, the Bank of India and India's ICICI Bank were the main players signed on to the agreement.
Led by ABN Amro, they are the most important financiers of the Antwerp trade, which handles about 80 percent of all rough diamonds and more than half of all cut stones traded globally.
Under the deal announced on Tuesday, the banks will provide new credit facilities up to 1 billion euros, for a period of two years, in exchange for diamond stocks, not normally used as collateral in the industry.
"The AWDC will be in charge of the valuation for the securities and the transparency of the operation, so as to secure the position of the banks," the AWDC said.
The scheme must still be approved by Belgium's banking and finance regulator.
In addition, the Flemish regional government was considering a request for a temporary additional guarantee of 200 million euros.
