There are concerns that the strains could become systemic across Greece, Ireland, Portugal and Spain, the so-called weaker PIGS members of the eurozone, and infecting potentially even Italy.
There is uncertainty about the structure of expected help for Ireland, and concern about what happens when an underlying EU-IMF rescue scheme for eurozone countries expires in two years' time.
Unicredit bank chief economist Marco Annunziata, commenting that help for Ireland might calm markets temporarily, also referred to these broader issues of contagion to other countries and strains in the eurozone.
"The real question which the markets are asking is what will happen after two years, at the end of the support programmes? Will it be really possible to avoid a restructuring of debt for these countries as EU leaders say?" he observed.
There is a growing view that any follow-up scheme to shore up eurozone countries in deep financial trouble would ensure that investors who had financed budget deficits with loans would end up losing a large part of their shirts because states would refuse to underwrite all the bills.
It is the policy line stated by German Chancellor Angela Merkel three weeks ago, which many analysts, and Greek Prime Minister George Papandreou, say was the trigger which blew the latest fuse.
Regarding Ireland, the government insists, and analysts largely accept, that the state has funded its state borrowing requirements up to the middle of next year and has set in hand a robust framework of corrective measures.
