Claim: Broad money (defined differently by the European Central Bank and the Bank of America) is defined by OECD as all banknotes and coins, and has the typical OECD notation of M5.
Evidence: The European Central Bank, the OECD and the Bank of England all have their own different definitions of broad money. OECD defines "broad money" as: all banknotes and coins; bank deposits not considered long term, i.e. with an agreed maturity of up to 2 years; bank deposits redeemable at notice of up to 3 months, and similar repurchase agreements; money-market fund shares or units; and debt securities maturing within a period of up to 2 years. The typical OECD notation for "broad money" is M3.
