You know a lot more about this than I do that is for certain. My understanding is that when actual deflation kicks in it is difficult to stop, guaranteed to have major dislocations of the specific economy and will be a long term problem. As in there is no easy fix and in our current global circumstances it will be very difficult for a place which has deflation kick in to get out of it. What are your thoughts.
Widespread deflation is devastating. It feeds on itself in a way that can disrupt local, national and global economies for decades. One concurrent feature is demand destruction which has the effect of driving deflation which causes more demand destruction which, in turn, accelerates deflation. They are self reinforcing. This is due, in part, to the wealth effects of deflation. Asset prices drop precipitously (think of the U.S. housing bubble) which causes less wealthy individuals to cut back on consumption.
The financial panic which began in 2007 brought us precipitously close to a depression. (It would have been far worse than the 30's because the global economy is so much larger.) This is why western nations pulled out all of the stops to stabilize the banking system. It helped. It prevented a catastrophe but we are not out of the woods. Entire areas of the world economy are still in a state of dramatic demand destruction. Think Spain and Greece where unemployment is 30% or greater.
Why are we in a very dangerous state right now? There are really very few financial tools left to prevent another major shock. Interest rates across developed nations are still at historic lows. QE (Quantitative Easing) was a financial trick to flood the U.S. economy with money. This would normally result in inflation, even rampant inflation. Why hasn't it? Because the demand destruction is overwhelming the impact of easy money.
Another thing to consider is how "real" interest rates behave in a deflationary environment. A nominal rate of .01% is actually a far higher "real" interest rate if we are suffering a 2% annual deflation. This discourages investment and reinforces the tendency to not invest in an economic environment that is dominated by demand destruction. In this situation, lowering interest rates loses its ability to increase borrowing and investment. Flooding the market with easy money is a little like pushing on a string. The front of the string does not move. Only increasing demand can pull the string (the economy) forward.
U.S. corporations are sitting on record amounts of cash. There are simply no investments worth making. Individuals are doing the same thing as the U.S. housing market has hardly budged. Why would you buy a home when your expectation is that the value of the home will drop?
Who are the big losers in a deflationary environment? Debt holders! All of them. Think about the mountains of bank debt, government debt and personal debt out there. What should you do to protect yourself? Reduce your personal debt. Reduce your investment exposure to debt and equity instruments. Cash is king. Of course, if the opposite is the case, if we are heading towards a period of rampant inflation, do the exact opposite. Buy stuff, lot's of it. The inflating asset prices will make the debt your holding seem paltry in a very short time frame.
My bet is on deflation.
