The European Central Bank’s continued asset buying program, along with a stronger euro on the heels of the French election, has helped balloon the ECB’s balance sheets, which have now surpassed the size of the US Federal Reserve, reports Bloomberg.

The spread between the ECB’s balance sheets and the Fed’s will likely continue to grow amid the ongoing asset buying program, with tapering not expected until next January. The ECB is expected to add another US$511.7 billion of assets before the end of the year.
