Italian banks have ramped up their reliance on the ECB for cheaper funding since the summer as the euro zone's third biggest economy was sucked ever deeper into the region's debt crisis and its lenders faced sharply higher refinancing costs.
The source, who declined to be named, said the meeting would be held in Frankfurt in Wednesday. The ECB declined to comment.
Earlier, the Corriere della Sera newspaper reported UniCredit Chief Executive Federico Ghizzoni saying he would ask the ECB "to extend the access to ECB liquidity by widening the type of collateral offered."
The request would also be on behalf of smaller Italian banks. UniCredit's five-year credit default swaps, measuring the cost of insuring its debt, widened by 40 basis points to 575 basis points after the news, on fears that under current liquidity provisions UniCredit might be under pressure.
The stock, which has shed around 12 percent since the beginning of the week and more than 50 percent since the start if the year, was up 0.8 percent at 0.75 euros, having trimmed earlier gains.
Ghizzoni said this week the bank, which holds 40 billion euros of Italian sovereign bonds, had solid liquidity and its geographical reach and strong retail network would help it reduce significantly the need for short-term funding.
According to the latest Bank of Italy data for the month of October, ECB funding to Italian banks rose to 111.3 billion euros ($150 billion)—almost three times the level of borrowing seen in June.
UniCredit, the only Italian name in a list of the most important global banks released this month, has not disclosed the size of its refinancing agreements with the ECB.

Ghizzoni is in Frankfurt for the annual Euro Finance Week meeting of central bankers, regulators and banking executives, and his visit comes two days after Italy's largest bank by assets unveiled a 7.5 billion euros rights issue after booking 9.8 billion euros of writedowns in the third quarter.
The CEO has announced a major shake-up of the bank's businesses to refocus it on retail and corporate operations, shrinking the volatile investment banking unit in the hope of reviving and stabilizing profits.
He also said that the bank would turn to issuing covered bonds and increasingly tap retail funding for its refinancing needs. Italian banks have effectively been shut off of the short-term wholesale market because of the sovereign crisis.
Analysts reacted skeptically to the plan, with many describing it as too ambitious in the face of a worsening economic outlook. Several also pointed out that the bank's funding re-mix strategy was costly.
In a sign of growing funding strains on traditional refinancing channels, UniCredit's net negative interbank position at the end of September rose to 67 billion euros, from 44 billion in the previous quarter, said Cheuvreux analyst Silvia Benzi.
"Going forward, this funding mix is barely sustainable, particularly in a context in which regulators are pushing for a more balanced funding structure," she said in a report.
The ECB has changed its collateral rules several times during the financial crisis to allow different types of assets to be used as collateral.
In addition, euro zone member central banks can choose to use Emergency Liquidity Assistance (ELA) to aid strapped banks.
The loans are given at the discretion of the national central bank although they have to be rubber stamped by the ECB. The collateral banks post when using the facility is typically of a lower average quality than is accepted by the ECB.
Both Ireland and Greece have used the ELA mechanism, which the ECB defines as support given by central banks in "exceptional circumstances and on a case-by-case basis to temporarily illiquid institutions or markets."
