Argentina 'to take over pensions'
The Argentine government is expected to announce plans to nationalise the country's 10 private pension funds.
The move will put the government in control of almost $30bn (£18bn) of investments, and is aimed at protecting them from the global market turmoil.
But expectations of the announcement has sent Argentine shares 12% lower, as investors fear what impact the decision will have on the stock market.
Critics accuse the government of simply wishing to get its hands on the funds.
They say the government needs the extra money ahead of a tough budget year.
As the 10 private pension funds are the country's largest institutional investors, the expected announcement has also hit the value of the peso and Argentine bonds.
Left-leaning President Cristina Fernandez is expected to announce legislation to introduce the changes. This will then go before parliament, which is also controlled by her Front for Victory political grouping.
