According to the article, the European Central Bank has disallowed the Greek government and Greek banks from putting up their own government bonds as collateral for loans from the ECB, dissolving a waiver previously granted to the Greeks despite being in junk bond status and having technically already been disallowed from this practice. This served as a warning shot to the potentially volatile and new Greek leftist, anti-austerity government, trying to prevent the new government from demanding a renegotiation of terms of debt and austerity in exchange for payment of debts incurred by the government. As a result, the new Greek government will be heavily reliant on Emergency Liquidity Assistance with its harsher array of terms and conditions, effectively giving over more control of the Greek economy to planners at the ECB.
The ECB, the central bank for all nations sharing the Euro as a currency, finds itself in a precarious position, significantly of its own making. The Greek sovereign debt crisis sparked the pan-Euro debt crisis, nearly causing the currency to collapse due to the heavy debt burdens of generally smaller, less-producing nations, such as Greece, Cyprus, and others, with the crisis nearly causing a crisis of confidence in larger nations with larger GDP, such as France. The ECB, mostly controlled by the solvent Germany, forced heavy austerity in exchange for financial rescue to keep the monetary status quo. Since then, the Euro crisis has been in a sort of suspended animation. This decision is an effort to keep the Euro at status quo on a trans-national scale to prevent wholesale collapse of either Greece or the Euro.
