Chief executives of Irish banks have now been told whether they have passed stress tests run by the European Central Bank.
Sources indicate Permanent TSB faces failing the process but will be able to raise money from financial markets instead of tapping taxpayer.
The results will not be made public until Sunday at around 11am. The ECB has asked banks not to make any disclosures until this point.
Today Minister for Finance Michael Noonan told news agency Bloomberg: "There's nothing in the pre-discussions that has surprised me."
Informed sources said the capital requirement for the bank would be likely to be more than €500m and less than €1bn.
However, the European Central Bank will include Permanent TSB's contingent capital of €400m, improvement its costs and other factors as counting towards making up the shortfall.
This is likely to lead to Permanent TSB raising the additional money it needs by selling shares on the stock market.
It is expected Bank of Ireland and AIB will pass the stress test.
Irish lenders are amongst the 130 euro zone banks receiving the ECB's final verdict on their finances today after a review aimed at drawing a line under persistent doubts about the health of the region's banking sector.
Most banks already have a good idea of how they have fared in the region's most comprehensive ever tests, after getting "partial and preliminary" results from the ECB in recent weeks.
But the final numbers were only agreed by senior regulators and supervisors last night.
The results will end months of uncertainty on what measures they will be forced to take to prove they can weather another economic crash.
Markets are expecting few surprises, and there have already been some reports of how banks have fared including a report in Spanish newswire Efe which named 11 banks as having failed.
The ECB's assessment, which is designed to allow the central bank to take over with a clean sheet when it becomes the euro zone's banking supervisor on November 4, is based on the banks' financial positions at the end of 2013.
The banks have strengthened their balance sheets by almost €203 billion since the middle of 2013, the ECB says, which implies that several banks which failed are likely to have already raised cash to deal with any shortfall.
Nonetheless, the outcome of the tests will be closely watched.
Over the past year, more than 6,000 experts combed through the banks' books to unearth any hidden losses and weaknesses.
As well as setting the ECB up for its new role as supervisor, the tests were also designed to remove investors 'lingering doubts about euro zone banks, which continue to trade at a discount to banks in the US.
Analysts say the results could pave the way for US investors, who are holding historically low levels of European bank equity, to pile back in since the banks' finances will have the seal of approval from a supranational body.
The ECB has repeatedly stressed the thoroughness of its review, which included a forensic assessment of whether banks had properly valued their assets and a stress test to see if they had enough capital to withstand another crash.
Officials privately guide that the process - which was far more intensive than three previous EU-wide bank tests - is at least as important as the actual outcome.
Market estimates of how many banks will fail the tests, and who those failures will be, are diverse, but generally investors are expecting few failures and surprises, especially amongst household names.
Technical failures would be those banks that missed the capital requirements as of end-2013, but which have since raised sufficient capital to meet the ECB's mark.
German co-operative mortgage lender Muenchener Hypothekenbank, for example, has already said it did not meet the capital requirement, but raised €400m in July to make up for it.
And Austria's part-nationalised lender Volksbanken has already said it would wind itself down to avoid a looming capital crunch that it was struggling to plug.
