His remarks came as market euphoria over the £80 million EU bail-out of Spanish banks subsided, with analysts still predicting some form of eurozone break-up.
"You only need to look round Europe to see what is happening to countries that did not have a clear plan to know that we are doing the right thing," said Mr Alexander.
His comments follow Scottish Finance Secretary John Swinney's view that George Osborne is adopting a "wrong-headed" approach to tackling the UK's economic problems. The Chancellor for his part claimed Britain's prospects of recovery were being "killed off" by the eurozone crisis.
Mr Alexander, in an interview with Holyrood Magazine, said of the eurozone crisis that it was striking "we haven't had anything at all from the SNP about what that could mean for an independent Scotland".
Describing the Yes campaign launch as a "damp squib", he said: "There was no new detail, no real answers to any of the questions people are asking – what about the currency, what about what is going on in the eurozone and what would that mean if they do want to be part of sterling and what would the impact be on their ability to maintain an independent fiscal policy, what is their view and detail on debt dynamics, what about the deficit, what about public finance and what about more bread and butter issues like passports?"
Mr Swinney yesterday noted how despite the problems in the eurozone, investment announcements from global companies like Diageo showed there were reasons for confidence in the future.
He stressed the Scottish Government would "continue to lobby the Chancellor to stop his emphasis on austerity and start the business of promoting growth" by boosting public sector capital investment and improving access to finance.
Meanwhile, the rise in stock markets following the Spanish bail-out disappeared yesterday as investors worried over its impact on public debt and how Sunday's Greek elections could deepen the eurozone crisis.
Madrid said it would stick to borrowing plans in face of the bail-out, aimed at rescuing banks battered by a property market collapse and recession rather than help Spain finance its budget deficit. Number 10 said it would have "no cost" implications for UK taxpayers.
