Critics of “New Age” monetary policy have been predicting that central banks would eventually run out of ways to trick people into borrowing money. There are at least three reasons to wonder if that time has finally come.

Wage inflation is accelerating

Normally, towards the end of a cycle companies have trouble finding enough workers to keep up with their rising sales. So they start paying new hires more generously. This ignites “wage inflation,” which is one of the signals central banks use to decide when to start raising interest rates. The following chart shows a big jump in wages in the second half of 2017. And that’s before all those $1,000 bonuses that companies have lately been handing out in response to lower corporate taxes. So it’s a safe bet that wage inflation will accelerate during the first half of 2018.

The conclusion: It’s time for higher interest rates.

The financial markets are flaking out

The past week was one for the record books, as bonds (both junk and sovereign) and stocks tanked pretty much everywhere while exotic volatility-based funds imploded. It was bad in the US but worse in Asia, where major Chinese markets fell by nearly 10% — an absolutely epic decline for a single week.

Normally (i.e., since the 1990’s) this kind of sharp market break would lead the world’s central banks to cut interest rates and buy financial assets with newly-created currency. Why? Because after engineering the greatest debt binge in human history, the monetary authorities suspect that even a garden-variety 20% drop in equity prices might destabilize the whole system, and so can’t allow that to happen.

The conclusion, central banks have to cut rates and ramp up asset purchases, and quickly, before things spin out of control.

So – as their critics predicted – central banks are in a box of their own making. If they don’t raise rates inflation will start to run wild, but if they don’t cut rates the financial markets might collapse, threatening the world as we know it.
