The European Central Bank will meet Thursday and, with monetary policy on hold for the moment, investors are waiting to hear more about President Christine Lagarde's plans for a full review that could include tweaking the target for inflation and supporting projects to limit global warming.

Lagarde has given broad outlines for the review but it has not been officially launched by a decision of the bank's 25-member governing council. The council meets in Frankfurt, Germany, with analysts saying no change is expected in interest rates or other monetary stimulus settings.

Lagarde took over from Mario Draghi on Nov. 1 at the head of the top monetary authority for the 19 countries that use the euro as their currency. The monetary policy review will be the first since 2003 for the bank, which was founded in 1998 ahead of the euro's launch in 1999.

One reason for the review is the bank's inability in recent years to reach its stated goal of inflation of “below, but close to, 2%.” Inflation averaged 1.2% over Draghi's eight-year term despite stimulus measures such as lowering interest benchmarks below zero and pumping 2.6 trillion euros ($2.9 trillion) into the financial system through bond purchases.

The current inflation goal is considered to offer a margin of safety against deflation, a vicious circle of falling prices, investment and slow growth. Some inflation also helps countries in the eurozone that are trying to improve their price competitiveness without having to fall into negative inflation themselves. The current goal could be replaced by a range or a different formulation.

Carsten Brzeski, chief economist at financial firm ING Germany, said that the review might have broad parameters at the start but “could end up changing very little.” He said a new definition of price stability of “around 2%” would give the bank some new flexibility to overshoot after periods of not reaching the target. Others have proposed a range, such as 1.5% to 2.5%.

Lagarde says the review will look at climate change and said that European institutions should support the fight against global warming, but cautioned that this must be done within their mandates. The ECB's legal mandate is to first seek price stability, and only after that to pursue the general economic goals of the union, such as growth and jobs.

The central bank doesn't buy bonds on environmental criteria but has in fact bought bonds that finance environmentally friendly projects as part of the broader effort to raise inflation.

Lagarde will also give her assessment of how things stand in the economy. She inherited a stimulus package enacted at Draghi's next-to-last meeting in September. The bank cut the deposit rate on money left overnight by commercial banks to minus 0.5% from minus 0.4% and started 20 billion euros ($22 billion) in monthly bond purchases. The package was aimed at supporting weak growth against headwinds from the U.S.-China trade dispute.
