See Line Item 7.1 in the ECB Balance Sheet here.
"The holdings by the Eurosystem of securities held for monetary policy purposes (asset item 7.1) increased by EUR 22.0 billion to EUR 155.7 billion. This increase was due to settled purchases under the Securities Markets Programme. Therefore, in the week ending 12 August 2011 the value of accumulated purchases under the Securities Markets Programme and that of the portfolio held under the covered bond purchase programme totalled EUR 96.0 billion and EUR 59.7 billion respectively. Both portfolios are accounted for on a held-to-maturity basis. (Ed: Must be nice!)"
Total purchases under this program were at about a E74B level for quite some time. Now it looks like the ECB has added to its portfolio another E22B in securities.
Somewhat related: The Fed has apparently also recently provided $500M to a single European Institution via the USD swap lines. Apparently, systemic external USD liquidity problems can occur at a single institution.
Viva la "Free Market"!
