Airlines/comapanies are looking at your decision making history. A track record of bad decisions whether it be failed checkrides, speeding tickets, DUIs, poor academic achievement, and yes even credit history, are likely determinents of future behavior.
Nobody is perfect and they know that, so they look at the "big" picture. If you have a clean record but had trouble making ends meet when you were furloughed it would not be an issue.
However,
Say you had bad grades, tickets, a failed checkride or three, late or missed payments because you bought both the harley and the boat then you have established a trend or "big picture" of poor judgement.
