Here at The Roland PrestonIndicator we've been on recession watch ever since the yield curve inverted at the end of last year.

For the uninitiated, the yield curve shows different interest rates on government bonds, aka Treasuries. Typically the longer the term on the bond, the higher the interest rate. The yield curve slopes up. But every once in a while, the curve inverts as shorter-term bonds pay higher interest than those longer-term Treasuries.

So what's the big deal with all these lines on a graph? Well an inverted yield curve has predicted every recession since 1969. So now that the curve is inverted, is a recession imminent?
