"The environment [in Washington] is going to become more anxiety-ridden," Charles Johnston, an attorney at the Baker Donelson law firm, said. Johnston oversees the firm's international transactions group.
Nevertheless, there are plenty of defenders of foreign investment in the United States, with some analysts arguing that the purchases amount to a "vote of confidence" in the long-term health of the US economy, even as individual banks and other companies struggle.
The flow of funds from overseas could bolster the US dollar, and sovereign wealth funds are the type of long-term investors that can stabilize the financial markets, said Doug Rediker, codirector of the international finance group at the New America Foundation.
Todd Malan, president of the Organization for International Investment, said the purchase of beaten-down companies in the US banking sector by overseas investment funds simply reflects a "classic buy low, sell-high strategy."
Malan's group represents US subsidiaries of overseas companies, such as Nestle, Sony Corp., and Nokia Corp.
The latest investments by state-run investment funds, known as sovereign wealth funds, were made public yesterday.
Citigroup Inc., the nation's largest bank, said it will receive nearly $7 billion in fresh capital from a sovereign wealth fund in Singapore, as well as investments from the Kuwait Investment Authority and Prince Alwaleed bin Talal of Saudi Arabia. Merrill Lynch & Co. said two state-run funds - the Kuwait Investment Authority and the Korean Investment Corp. - and a Japanese investment bank would invest $6.6 billion.
Sovereign wealth funds, which are found mostly in the Middle East and Asia but also in European countries such as Russia and Norway, control an estimated $2.5 trillion in assets. Some experts predict their holdings could reach $12 trillion by 2015.
This fall, analysts noted the sovereign funds were seeking to avoid regulatory scrutiny by structuring their deals in certain ways: The stakes were small, they did not include board seats or other levers of control, and they generally avoided sensitive industry sectors such as energy or government contracting.
