The eurozone’s big banks will meet again in Paris on Wednesday in an attempt to end the deadlock with European authorities over the terms of investors’ participation in the restructuring of Greek sovereign debt.

According to people briefed on the talks, a new proposal will ease the burden on Greece, sweetening the terms of the banks’ original plan that would have seen them roll over for 30 years half of their holdings of Greek debt due to mature in the next three years.

The banks met last week in an effort to thrash out the terms of that voluntary plan. They used a blueprint drawn up by the French banking federation. Under that plan, the rolled-over debt would have carried an interest rate capped at 8 per cent, comprising a basic 5.5 per cent coupon plus a “kicker” of up to 2.5 per cent depending on Greek economic growth.
