Even as ECB president Jean-Claude Trichet aimed to calm markets by indicating the central bank is not embarking on a series of interest-rate increases after Thursday’s quarter-percentage point hike to 4.25%, he may also have rattled some nerves by suggesting policy makers are reviewing the bank’s collateral policy and that euro-zone living standards may be headed down.


Amid market tensions, the ECB’s broad collateral policy - which has always included accepting mortgage-backed securities in exchange for central bank funds - has been a boon to markets and a model for central banks including the Fed and Bank of England, which have broadened their collateral policies in turn.

But amid suggestions some banks are exploiting the ECB’s generous policy, Mr. Trichet Thursday gave the most serious hint yet that policy makers are eyeing the bank’s collateral criteria. “Our collateral framework has served us very well,” he said in the press conference following Thursday’s interest-rate decision. “We are permanently examining and applying our rules with great care … If it is necessary to refine elements in our scheme … we shall see what we have to do.”

ECB executive board member Jose Manuel Gonzalez-Paramo said last month that the bank is studying whether the rules on collateral “may need to be refined.”

Separately, Mr. Trichet Thursday also warned euro-zone citizens that rising global prices might mean an unavoidable reduction in euro-zone living standards: “The shift in relative prices and the related transfer of income from commodity-importing countries to commodity-exporting countries have to be accepted,” Mr. Trichet said. Warning euro-zone consumers and firms to adjust their behavior accordingly, he also tossed a shot across the bow of oil suppliers.

“We also tell the suppliers that to the extent that part of the prices are coming from this cartel this is very, very abnormal,”he said, noting that, globally, “when we have a demand-driven increase in prices then it plays a role in the automatic stabilization of global growth. But if we have a supplier-driven artificial scarcity then it is very grave.”

In a rare move, Mr. Trichet also criticized supply constraints, saying, “there are a number of industrialized countries preventing drilling … that are preventing exploration of new fields.” When questioned, he declined to specify which countries he meant. – Joellen Perry
