Sure, it signifies growing economic strength and confidence … but what about the downside?

According to the latest estimates, U.S. credit card balances are expected to hit $1 trillion by the end of 2016.

It’s a milestone of sorts.  After all, the last time Americans’ total credit card balances exceeded $1 trillion was in 2008, just before the onset of the “Great Recession” as the housing/financial crisis intensified.

Does this new peak herald the end of the frugal consumer spending habits which transpired in the wake of the recession?

Perhaps so … but a good deal of the explanation reflects on the financial institutions themselves, who began opening the spigot by relaxing restrictions on signing up subprime consumers.

They’ve also begun raising credit limit amounts.

All this is a change from before, when credit-tightening was the name of the game from 2009 onwards.

Part of what’s driving the new policies is the fact that credit cards represent one of the few bright spots in consumer finance at the moment.

To illustrate the point, large credit-card issuer Capital One reports a year-over-year gain of nearly 15% in the 1st quarter of 2016 compared to a year earlier.  Other major issuers — Citigroup, J.P. Morgan Chase and Discover Financial Services among them — also have experienced significant gains.

By contrast, other consumer lending activities are far less lucrative, because low interest rates make margins on traditional lending very low.

I wonder if the rush to ply subprime borrowers with new general-purpose credit cards is a smart long-term proposition, however. Nearly 11 million such cards were issued in 2015.  That’s ~25% higher than in 2014 and the highest number of such cards issued annually since 2007.

Couldn’t the next bout of economic turbulence put us right back into a bevy of defaults as before?  And aren’t we seeing hints of this already?

Here’s a clue:  defaults rates appear to be rising along with the issuing activity — including a steady uptick in each of the first four months of this year.

And let’s not forget automobile loans, either.  They’re up significantly as well — along with delinquency rates.

I think history can help guide us here — and with a lot more caution than was the case back in those halcyon days of 2007.  If there are problems, no one can say that we weren’t forewarned, based on recent history.
