Think about it.
Cheap money allows people to borrow at minimal cost.
People, being motivated by profit, see that cheap money can be invested elsewhere (like equities, real estate, or, say commodities) where the return on that investment will be greater than the interest they have to pay.
Viola. Profit.
So people - across the globe - take loans from commercial banks and invest them in all the assorted sectors just mentioned.
Often times, bubbles form due to the herd like behavior of people.
Real Estate is first in line because, fundamentally, home sales are tied closest to rates. Low rates and not enough homes = frenzied buying and RE development. Smart money piles in. Then the masses. Then the FED stops the party and bagholders walk home, sullen in the night.
But all that smart money doesn't go away. It goes somewhere else. A new sector. This time, it piled into commodities which were fundamentally driven by the inflationary RE boom earlier in the decade. And so on and so on.
Smart money seeks profit. It doesn't sit in an interest bearing savings account earning a negative 5% after inflation.
Its aggressive. It finds opportunities and front runs.
The rub is speculators can't afford to margin crazy if the cost of money is high. Whose going to leverage at 100 to 1 when the juice on that 100 is 10 or 15%. Thats tough.
And that takes the wind out of the sails of most funds and institutional investors that can barely eek out 20% a year - with margin cost at 3%.
Think about it.
At 15% interest, most funds would close shop because they can't make enough profit to cover the cost of the juice and have enough left over to satisfy their investors.
POOF. GONE. Speculation days are over.
Now the guys that can take 40% YOY outta the market stick around. But they are few and far between.
All this money out there - some 75% of funds can't beat the S&P - all that money is gone when rates go up. This whole financial industry thrives on cheap money because funds can't survive without it. Because they can't trade worth a shit.
Interesting premise.
