I have been thinking a fair amount about inflation over the past months and this is a short summary of my understanding of inflation and general thoughts. It is a mixture of uninformed opinion and conjecture.
Inflation can be thought of an invisible tax. Whatever it is you have saved will buy you less in the future than it will do now. If you look at is as a tax it is a particularly clever one as even collects its self (no bureaucracy requited) whatever money you have is taxed.
The way that inflation affects you is dependent on what you buy. One of the most memorable accounts of inflation I came across was from Ron Hosen (a value investor) who discounted reports of inflation on the grounds that he had seen little inflation in the goods that he bought - most notably rotisserie chickens. In rotisserie chicken terms Ron had seen no price change at all so he was entirely correct in identifying that there was no inflation. I live in a different part of the world and consume a different set of goods than Ron and I have been experiencing a much higher level of inflation. Things just cost more, that is the things that I buy cost more. Most notably food costs more, gas and electricity costs more and for many years council tax has increased. If, in a homage, to Ron (who I have a lot of respect for) I look at poultry as a measure of inflation then when Virginia, now my wife, moved in eight or so years ago Tesco's economy turkey legs (there really is a meal for two in a leg and a damn good one if she cooks it) which were 89p each and now are I think £1.25 - is that 40% in eight years.
The serious part about inflation is what it affects and how it affects you. The government RPI and CPI are based on a set of goods and services. If your consumption is different from either of these two sets (and it will be) then inflation will affect you differently. If you, over the last few years, have bought consumer electronics then inflation has been kind to you. For many other goods (what I would consider the basic staples) it has not.
The counterpart of goods inflation is wages inflation. Over the last couple of years my wages have risen buy about 1% a year so I am a net looser. I mention this as an example rather than some kind of back-handed complaint, I am not complaining. However lets look at it - as my wages do not keep up with inflation the invisible tax gnaws away at my future earnings, and so attacks my future ability to save as well as what I have managed to save. Happy as I am with my job (great job BTW) financially I am bitch-slapped. We are currently in difficult economic times so generally people are relived to have a job - which makes wage inflation less likely. Even if they are not pleased with this, when the economy is slow the opportunities for moving to a new job are not good. As I understand it this sort of state of affairs is called Stagflation.
So does anyone benefit from inflation? Well if you get inflation your savings are attacked. If inflation is greater than interest you actually end up with less as time passes. Just look at your savings as "Tesco's economy turkey legs" and you have less. But what if you have debt? Well this is interesting - as long as your wages rise corresponding to inflation then your debt gets cheaper. At the moment at the NationWide building society I can borrow money at 7% or so for a personal loan - if inflation is 5%, and my wages were to keep up what do I care - as hey presto my loan is just 2% in "Tesco's economy turkey legs". If you are a government that can not balance it's books and has debt you can nibble away at it with inflation. What is owed shrinks. And who pays? well those who lent it money.
Looking at the medium term I personally expect inflation, to continue at levels greater than the Bank of England target (2%) and I would imagine greater than wages. Why? Well we are at the start of a new era where the balance of the world allocation of wealth and resources is changing. Currently 20% of the population have 80% of the wealth and this is changing. Also there are simply more people in the world - the population of the world is compounding. What this means for us (one of the 20%) is that it would seem that there is going to be just less to go around. A part of this is that we have limited natural resources and these will have to be spread differently, but also we have limited capabilities for growing food and that the world GDP won't necessarily increase fast enough to stop the people with more having less.
Naïvely, from my point of view, one of the things that seems to have kept inflation low in the UK is the influx of Chinese [imported] goods over the past years. My guess is that our currency has hung in there stronger than it should as our economy has reenforced its self on mushrooming consumer debt. So things change - debt is not indefinitely sustainable. Politically any boom is good, and the reverse looses you elections. So with when Brown was talking prudence and was fighting with No 10 and managing our economy the consumer led boom bubbled up with consumer debt. I suspect that the economy was really weaker than it seemed to be (debt made it appear stronger) and as we come to terms with this we experience the weakness we should have had - but with "interest" as there is never a free lunch.
Goods from China will become more expensive. China has growing aspirations, a growing middle class, growing wages. Recently the yuan has been allowed to appreciate against the dollar and my guess is that this appreciation will continue. I am sure that production in China will become ever more efficient - but I also can't fail to see that prices won't increase. How else do you pay for a growing middle class. I mention China as it is large, and in the forefront of people's minds, but it is not the only accelerating emerging economy.
Assuming inflation bites down on, and our wages fail to keep pace what will the effect be? We will have less and more of what we have will be spent on essentials. On the back of this is it not reasonable to assume that house prices will fall and rent will fall. Why? well rent and house prices soak up a huge amount of the slack in your personal finance. Discretionary spending will suffer.
The key issue here is the rate of change, the rate at which we become poorer. Go to Cuba and the average Cuban says "we have nothing". Compared to much of the 3rd world the average things are not bad in Cuba (though I will say for the avoidance of doubt not as we have it in the west by a large margin). As a whistle stop summary life expectancy of 76, education is good, more-or-less complete adult literacy. They have food, housing, low unemployment, strong family. Their perception has, to an extent, been colored by a sudden horrific drop in their standard of living. Compared to how they were before the fall of the soviet union and ratcheting up of the US trade embargo they have little. If this change had seeped in slowly over a generation or two it might have been easier.
So what do I hope for? Well I hope for a reasonable rate of change - that way we can adapt and adjust. Change upsets people, it is confusing, too much of it all at once always causes problems.
