Here's what the market could be about to do for the third time in 17 years

Traders work the floor of the Dow Jones at the closing bell of the New York Stock Exchange.

The major averages continue to set record highs, which provides further evidence that Wall Street is becoming more complacent with the growing dichotomy between equity prices and the underlying strength of the U.S. economy. When investors view the Wiltshire 5000 total market cap to GDP ratio, it becomes strikingly clear that economic growth has not at all kept pace with booming stock values in the past few years.

The reason for this huge discrepancy is clear: massive money printing by the Fed has led to rising asset prices; but at the same time has failed to boost productivity. In fact, since Quantitative Easing (QE) began back in November of 2008, the Fed's balance sheet has grown from $700 billion, to $4.5 trillion today. That is an increase of 540 percent! Yet, during the same time period U.S. GDP has only managed to increase from $14.5 trillion, to $18.8 trillion. For a comparative measly blip in growth of just 29 percent.

And this anemic state of GDP growth shows no signs of picking up steam, despite the hype and hope from Wall Street regarding the new president. After growing at just about 2 percent per year since coming out of the Great Recession, the Atlanta Fed's GDP Now forecast model has first quarter GDP growth coming in at a below-trend rate of just 1.3 percent.

But what's even worse is the denominator in that market cap to GDP equation has been artificially supported by that same central bank QE and artificially-low interest rates. This distorted type of Fed-engendered economic growth comes from encouraging the accumulation of more debt through the process of making loans dirt cheap.

Indeed, the housing bubble economy of a decade ago was abetted by taking the Fed Funds Rate (FFR) to one percent from June 2003-June 2004. Likewise, today's housing, equity and bond bubbles found their birth from a zero percent Fed Funds rate that was extent from December 2008-December 2015—and still stands below 1 percent today.

So what we have is an extremely dangerous situation indeed. While record high stock prices have become more detached from economic reality than ever before, the Fed has encouraged debt levels to surge to a record as well. And because robust growth has been absent, the level of the U.S. 10-year Note can't seem to get above 2.5 percent.

According to the Federal Reserve's Flow of Funds Report, the level of total non-financial debt has soared from $35 trillion back in 2008, to over $47 trillion in the third quarter of 2016. As mentioned, this growth has been boosted from new debt issuance, and that debt compulsion is the result of QE and a zero interest rate policy (ZIRP). But now ZIRP is in the process of going away.

The last time the Fed began a rate hiking cycle was back in June of 2004. At that time the Funds Rate was 1 percent and the 10 Year Note was 4.75 percent, for a spread of 375 basis points. However, that spread between the (FFR) and the 10 year now stands at just 175 bps.

Therefore, unless President Trump can pass his aggressive fiscal stimulus plan imminently, it is likely that the yield curve will flatten out much quicker than at any other time in history due to that current tight spread. As the Fed continues to slowly raise rates, expect long-term rates to fall due to deflating stock and home prices, and a weakening economy.

The truth is it will probably only take a handful of rate hikes to cause the yield curve to resemble a very flat pancake. Why is that important? A flat or inverted yield curve has most often led to a recession and carnage in the stock market; just as it did prior to the huge collapse in equities during 2000 and 2008. In fact, the Fed has a long history of cycling between lowering rates too much, causing a steepening yield curve, then raising rates too quickly and flattening it out.

Only this go around, when short-term rates rise to meet long-term borrowing costs the ensuing recession will occur with record-low interest rates, unrivaled debt levels, unparalleled real estate prices and unprecedented stock prices.

Bond yields are, historically speaking, "in the basement" and the public and private sectors are already saturated in debt. Therefore, there just isn't much the government can do to encourage another round of debt accumulation to pull the economy out of a death spiral as it did in the wake of the Great Recession.

Janet Yellen thinks she can normalize interest rates with impunity during this current hiking cycle. If that is indeed the case, look for a flat yield curve and recession by year-end to wipe out 50 percent of equity prices for the third time in the past seventeen years if the Fed follows through on plans to hike three times in 2017.
