Russian President Vladimir Putin's invasion of Ukraine has added an extra layer of complexity to the decisions facing European Central Bank (ECB) policymakers as they meet on Thursday.
Already managing record inflation figures and a fragile recovery from the impact of the coronavirus pandemic, members of the bank's 25-member governing council now have to reckon with the impact of war on the edge of the eurozone.
The pace of consumer price rises shifted up a gear in February, rising to 5.8% from 5.1% the previous month, a new all-time high for the euro area.
The spike has been driven in no small part by soaring prices for energy, caught in the middle of the conflict with Russia, a major supplier to European countries.
ECB President Christine Lagarde responded to the Feb. 24 invasion by saying the central bank would "take whatever action is necessary" to stabilize the euro region's economy.
Prices for gas and oil were "likely in the short term to increase inflation," she said, sustaining it for longer than the bank previously expected.
Soaring inflation has put the ECB under pressure to follow its peers in the United States and Britain by moving to end its economic stimulus and raise interest rates soon.
At its last meeting at the beginning of February, the ECB left its plan for a "step-by-step" reduction in its asset-purchasing programs untouched.
The pandemic emergency bond-buying program, which has been the ECB's main crisis-fighting tool, aimed at keeping borrowing costs low to stoke economic growth, will come to an end in March.
Under the current guidance, a separate pre-pandemic bond-buying scheme will be boosted to 40 billion euros ($44 billion) monthly in the near term and carry on till at least October.
Any policy tweaks were pushed back to the meeting this week, when the governing council will make use of new economic forecasts to support their decision making.
In December, when the figures were last updated, the bank foresaw inflation at 1.8% in 2023, below its two-percent target.
The new inflation projections, which will take account of the Ukraine conflict and the most recent data, could see a sharp upwards revision.
The outlook was however shrouded in "significant uncertainty," ECB executive board member Isabel Schnabel said after Russian tanks moved on Ukraine.
At the same time, the high cost for energy was likely to weigh on the economy and slow production, narrowing policymakers' room for maneuver.
The double risk will encourage the ECB to "tread carefully," said Andrew Kenningham of Capital Economics.
It will also encourage the bank to give a signal it "could even step up support if needed," he added.
In Russia, where the economy is reeling from Western sanctions, central bankers propped up the ruble by more than doubling the main interest rate to 20%.
Such high levels are completely alien to the ECB which has long kept its rates at historic lows, including a negative deposit rate that effectively charges banks to park their cash overnight.
But more "hawkish" members of the governing council who would like to see the ECB act faster have grown more vocal.
Inflation fears meant policymakers needed to keep their "sights trained on the normalization of our monetary policy," Bundesbank chief and governing council member Joachim Nagel said.
Observers will be listening closely to Lagarde's news conference at 2:30 p.m. local time (1:30 p.m. GMT) to see if the former French finance minister makes any advance on her pledge for the ECB to be "data-driven."
Lagarde's previous insistence that any hike in 2022 was "very unlikely" disappeared after the February meeting, as markets bet on an earlier increase.
In light of the tense situation in Europe, "the ECB will want to avoid hinting at end dates" for its bond-buying "or start dates for rate hikes," said Carsten Brzeski, head of macro at the bank ING.
Instead, Lagarde could follow her predecessors to "never pre-commit," Brzeski said.
