Investors around the world have been confused, befuddled and surprised by the persistent, ultra low level of long term interest rates in the United States.

At today?s close, the 30 year Treasury bond yielded a parsimonious 2.01%, the ten year, 2.62%, and the five year only 1.51%. The ten-year was threatening its all time low yield of 1.37% only two weeks ago, a return as rare as a dodo bird, last seen in August, 2012.

What?s more, yields across the entire fixed income spectrum have been plumbing new lows. Corporate bonds (LQD) have been fetching only 3.29%, tax-free municipal bonds (MUB) 2.89%, and junk (JNK) a pittance at 5.96%.

Spreads over Treasuries are approaching new all time lows. The spread for junk over of ten year Treasuries is now below an amazing 3.00%, a heady number not seen since the 2007 bubble top. ?Covenant light? in borrower terms is making a big comeback.

Are investors being rewarded for taking on the debt of companies that are on the edge of bankruptcy, a tiny 3.3% premium? I think not.

It is a global trend.

German bunds are now paying holders 0.35%, and JGB?s are at an eye popping 0.30%. The worst quality southern European paper has delivered the biggest rallies this year. Portuguese government paper is paying only 2.40%, and is rapidly closing in on US government yields.

Yikes!

These numbers indicate that there is a massive global capital glut. There is too much money chasing too few low risk investments everywhere. Has the world suddenly become risk averse? Is inflation gone forever? Will deflation become a permanent aspect of our investing lives? Does the reach for yield know no bounds?

It wasn?t supposed to be like this.

Almost to a man, hedge fund managers everywhere were unloading debt instruments in January. They were looking for a year of rising interest rates (TLT), accelerating stock prices (QQQ), falling commodities (DBA), and dying emerging markets (EEM). Surging capital inflows were supposed to prompt the dollar (UUP) to take off like a rocket.

It all ended up being almost a perfect mirror image portfolio of what actually transpired since then. As a result, almost all mutual funds are down so far in 2014. Many hedge fund managers are tearing their hair out, suffering their worst year in recent memory.

What is wrong with this picture?

Interest rates like these are hinting that the global economy is about to endure a serious nose dive, possibly even re-entering recession territory?or it isn?t.

To understand why not, we have to delve into deep structural issues, which are changing the nature of the debt markets beyond all recognition. This is not your father?s bond market.

I?ll start with what I call the ?1% effect.?

Rich people are different than you and I. Once they finally make their billions, they quickly evolve from being risk takers into wealth preservers. They don?t invest in start-ups, take fliers on stock tips, invest in the flavor of the day, or create jobs. In fact, many abandon shares completely, retreating to the safety of coupon clipping.

The problem for the rest of us is that this capital stagnates. It goes into the bond market where it stays forever. These people never sell, thus avoiding capital gains taxes and capturing a future step up in the cost basis whenever a spouse dies. Only the interest payments are taxable and that at a lowly 20% rate.

This is the lesson I learned from servicing generations of Rothschild?s, Du Ponts, Rockefellers, and Getty. Extremely wealthy families stay that way by becoming extremely conservative investors. Those that don?t, you?ve never heard of, because they all eventually went broke.

This didn?t used to mean much before 1980, back when the wealthy only owned 10% of the bond market, except to financial historians and private wealth specialists, of which I am one. Now they own a whopping 23%, and their behavior affects everyone.

Who has bee the largest buyer of Treasury bonds for the last 30 years? Foreign central banks and other governmental entities, which count them among their country?s foreign exchange reserves. They own 36% of our national debt, with China in the lead at 8% (the Bush tax cut that was borrowed), and Japan close behind with 7% (the Reagan tax cut that was borrowed). These days they purchase about 50% of every Treasury auction.

They never sell either, unless there is some kind of foreign exchange or balance of payments crisis, which is rare. If anything, these holdings are still growing.

Who else has been soaking up bonds, deaf to repeated cries that prices are about to plunge? The Federal Reserve, which thanks to QE1, 2, and 3, now owns 22% of our $17 trillion debt. Both the former Federal Reserve governor Ben Bernanke, and the present one, Janet Yellen, have made clear they have no plans to sell these bonds. They will run them to maturity instead, minimizing the market impact.

An assortment of other government entities possess a further 29% of US government bonds, first and foremost the Social Security Administration, with a 16% holding. And they ain?t selling either, baby.

So what you have here is the overwhelming majority of Treasury bond owners with no intention to sell. Only hedge funds have been selling this year, and they have already done so, in spades.

Which sets up a frightening possibility for them, now that we are at the very bottom of the past year?s range in yields. What happens if bond yields fall further? It will set off the mother of all short covering squeezes and could take ten-year yield down to match the 2012, 2.38% low.

Fasten your seat belts, batten the hatches, and down the Dramamine!

There are a few other reasons why rates will stay at subterranean levels for some time. If hyper accelerating technology keeps cutting costs for the rest of the century, deflation basically never goes away (click here?for ?Peeking into the Future with Ray Kurzweil?).

Hyper accelerating corporate profits will also create a global cash glut, further levitating bond prices. Companies are becoming so profitable they are throwing off more cash then they can reasonably use or pay out.

This is why these gigantic corporate cash hoards are piling up in Europe in tax free jurisdictions, now over $2 trillion. Is the US heading for Japanese style yields, or 0.39% for 10 year Treasuries?

If so, bonds are a steal here at 2.55%. If we really do enter a period of long term -2% a year deflation, that means the purchasing power of a dollar increases by 35% every decade in real terms.

The threat of a second Cold War is keeping the flight to safety bid alive, and keeping the bull market for bonds percolating. This could put a floor under bond prices for another decade, and Vladimir Putin?s current presidential run could last all the way under 2014.

All of this is why I?m out of the bond market for now, and will remain so for a while.

Why Are They So Low?
