Is inflation a good or bad thing? Why do governments want some inflation?
"Sensitive topic ;) Inflation is a consequence of the mismatch between supply and demand.  In an ideal world the amount of goods available would exactly match the demand for those goods.   We don't live in an ideal world. One example of oversupply is dollar stores where you can buy remainders from companies that misjudged demand.  Most recently we've seen wheat prices rise as fires outside Moscow damaged the harvest and the Russian government banned exports. And that introduces the danger of inflation. Inflation is a signal, like the pain you feel after an injury.  If you simply took a painkiller you may completely ignore a broken leg until gangrene took your life. Governments sometimes ""ban"" inflation by fixing prices.  Both the Zimbabwean and Venezuelan governments have tried this recently.  The consequence of that is goods become unavailable as producers refuse to create supply for less than the cost of production. As CrimonsX pointed out, governments do desperately want to avoid deflation as much as they want to avoid hyperinflation. There is a ""correct"" level and that has resulted in the monetary policy called ""Inflation targetting"" where central banks attempt to manage inflation into a target range (usually around 2% to 6%). The reason is simply that limited inflation drives investment and consumption.  With a guaranteed return on investment people with cash will lend it to people with ideas.  Consumers will buy goods today if they fear that the price will rise tomorrow. If prices fall (as they have done during the two decades of deflation in Japan) then the result is lower levels of investment and employment as companies cut production capacity.  If prices rise to quickly (as in Zimbabwe and Venezuela) then people cannot save enough or earn enough and so their wealth is drained away. Add to this the continual process of innovation and you see how difficult it is to manage inflation at all.  Innovation can result in increased efficiency which can reduce prices.  It can also result in a new product which is sufficiently unique to allow predatory pricing (the Apple iPhone, new types of medicines, and so on). The best mechanism we have for figuring out where money should be invested and who is the best recipient of any good is the price mechanism.  Inflation is the signal that investors need to learn how best to manage their efforts. We hide from it at our peril." "Basically, in any financial system that features fractional reserve banking, the monetary supply expands during times of prosperity. Stable, low inflation of 2-4% keeps capital available while keeping the value of money stable. It also discourages hoarding of wealth. Banks aren't vaults. They take deposits and make an explicit promise to repay the depositor on demand. Since most depositors don't need to withdraw money regularly, the lend out the money you deposited and maintain a reserve sufficient to meet daily cash needs. When times are good, banks lend to people and businesses who need capital, who in turn do things that add value to the overall economy. When times are bad, people and businesses either cannot get capital or pay more for it, which reduces the number of times that money changes hands and has a negative impact on the wider economy. People who are trying to sell you commodities or who have a naive view of how the economy actually works decry the current monetary system and throw around scary words like ""fiat currency"" and ""inflation is theft"". What these people don't realize is that before the present system, where the value of money is based on promises to repay, the gold and silver backed systems also experienced inflation. With gold/silver based money, inflation was driven by discoveries of gold and silver deposits" "Inflation, like trade deficits or surpluses, have winners and losers in an economy. Clear losers are people who are on a fixed income, as they often have a fixed income and a prices keep on going up, meaning they can afford less.  Numerous articles on the internet discuss the inflation of the 1970s, here are Google's results.  I'm not so sure that governments want ""some inflation"" as much as they desperately want to avoid deflation. Deflation means that the price for today's product, like a car, will decrease in price tomorrow (or a month from now) which creates a powerful incentive for people to put off a purchase until later, which brings consumer demand down in a country's economy." "Although there are some good points made here as to the cause of inflation (mostly related to supply and demand), azcoastal does head in a different direction, one which I myself was going to take. Let me give a different angle, however. Another cause of inflation is the printing of money by the government (not simply replacing old money with new, but adding to the total money in circulation). If the government doubles the amount of currency in circulation (for the sake of argument and easy math), the value of all money decreases by a factor of 2. That's inflation, and the way G. Edward Griffin in The Creature From Jekyll Island puts it, it's really tantamount to a hidden tax. In a nutshell, the federal government wants to buy some cool stuff like new tanks or planes, or they want to give a bunch of food stamps to poor people, or they want to fly their private jets around, but they don't have enough money from taxes. So, they print money and spend it and buy their stuff. Because they've just increased the money in circulation, however, money loses its value. For example, your savings has dropped in value by half, despite the fact that the same number of dollars is in your savings account. This is just a way the government can tax you without taxing you. They buy stuff and you now have less money (i.e., your retirement is worth less) and you don't even know you just got taxed. Makes me sick that we let our ""leaders"" get away with this." Inflation is what happens, it is not good or bad in and of itself.  But consider the following. In a thriving economy with low unemployment, people are buying, buying, buying.  People are not saving for later, they are buying now.  Industry is also making purchases.  Now.  From economics 101: high demand for goods/services leads to relative scarcity leading to higher prices.  Inflation tends to be one byproduct of a thriving economy.  Governments want the thriving economy that brings inflation with it. "The classic definition of inflation is ""too much money chasing too few goods.""  Within a tight range, say 1-3%, inflation is somewhat benign.  There's a nice inflation widget at The Inflation Calculator which helps me see that an item costing $1000 in 1975 would now (2010) be about $4000, and $1000 from 1984 till now, just over $2000. I chose those two years to make a point. First, I am 48, I graduated college in 1984, so in my working life I've seen the value of the dollar drop by half. On the other hand it only took 9 years from 75-84 to see a similar amount of inflation occur.  I'd suggest that the 26 year period is far more acceptable than the 9. Savers should be aware of their real return vs what was a result of inflation. I'm not incensed either way but logically have to acknowledge the invisible tax of inflation. I get a (say) 6% return, pay 2% in tax, but I'm not ahead by 4%, 3% may be lost to inflation. On the flip side, my mortgage is 3.5%, after taxes that's 2.625%, but less than 0% after (long term) inflation. So as a debtor, I am benefiting by the effect of inflation on what I owe.  Interesting also to hear about deflation as we've grown used to it in the case of electronics but little else. Perhaps the iPad won't drop in price, but every year it will gain features and competitors will keep the tablet market moving. Yet people still buy these items.  Right now, there's not enough spending. I'd suggest that, good financial advice aside, people as a whole need to start spending to get the economy moving. The return of some inflation would be a barometer of that spending starting to occur." "In general the consensus is that a small amount of inflation (usually 1.5-2% per year) is desirable.  That is why the Federal Reserve sets its inflation target in that range.  The reasons why are quite complex though. One reason is ""wage stickiness"" - ie., the observed phenomenon that employers don't like to cut wages.  Having a small rate of inflation means that when wages are steady in nominal terms, they are actually falling in real terms.  This gives employers more flexibility." Inflation is an increase in the money supply.  Increases in consumer prices follow from inflation.  It's not the same as inflation. Some inflation is necessary for a growing economy.  If your gross national product is only $1,000, then you can get away with having less money than if your gross national product is $1 trillion. Inflation beyond this, though, is used to allow governments to live beyond their means.  If there is more money chasing the same amount of goods, prices will rise.  There is truth in what azcoastal says about this kind of inflation.  It's theft. Governments like inflation because it allows them to pay off their debts with cheaper money. If there's no inflation (or alternately there's deflation) people would tend to sit on money and wait for the prices to drop. This in pretty bad for pricier stuff like real estate/housing industry where a few percent can make a big difference.  For a growing economy a small inflation is good as people would go out and buy new stuff when they want it knowing they will not get a better deal if they wait a year or so. "Inflation is a bad thing.  It makes it much more difficult for people to compare prices and prosperity over a long period of time.  This causes people to ignore the wisdom of their elders (who remember prices from a long time ago). Back in my day, you could get a burger and fries for 15 cents -- a dime for the burger, and a nickel for the fries.   But the minimum wage was only a quarter an hour!  That doesn't help me decide if things have gotten better or worse. How long is ""a long period of time""?  That depends on the inflation rate. At 1 percent per year, 50 or 100 years is ""a long time"". At 10 percent per year, 5 or 10 years. At 100 percent per year, a few months. Because of the Spanish conquests of gold and silver mines in Mexico and Peru, prices in the sixteenth century rose by a factor of 5.5 during the century.  This inflation was recognized as causing lots of social and governmental problems.  Note that this means an average inflation rate of 2 percent per year for a century is known to be a very bad thing. There are several reasons that most governments want some inflation:" Inflation is theft!  It is caused when banks lend money that someone deposited, but still has claim to - called fractional reserve banking.   On top of that, the Federal Reserve Bank (in the US) or the Central Bank of the currency (i.e. Bank of Japan, European Central Bank, etc.) can increase the monetary base by writing checks out of thin air to purchase debt, such as US Treasury Bonds. Inflation is not a natural phenomenon, it is completely man-made, and is caused solely by the two methods above. Inflation causes the business cycle.  Lower interest rates caused by inflation cause long-term investment, even while savings is actually low and consumption is high.  This causes prices to rise rapidly (the boom), and eventually, when the realization is made that the savings is not there to consume the products of the investment, you get the bust. I would encourage you to read or listen to The Case Against the Fed by Murray N. Rothbard - Great book, free online or via iTunes.
"The markets now are projecting inflation over the next 10 years of only [1.19 percent](http://www.clevelandfed.org/research/data/inflation_expectations/). That's the lowest since the deflation that drove the Great Depression.  And prices just **fell** [in May](http://tucsoncitizen.com/usa-today-news/2012/06/14/consumer-prices-fall-0-3-in-may/), *deflation* once again.  The last time before this that prices *fell* was the last half of 2008 -- the start of the Great Recession.  So we have prices **falling** again, and the last time two times we had unexpected significant price falls they gave us the Great Depression and Great Recession.  Anyone who is actually afraid of inflation today is somewhere between being totally out of touch with reality and being an obsessive loon.  &gt;So just help me figure out why there are economic arguments against purposefully high inflation (5%)  You *don't* want ""purposely high inflation"".  One party's gain with that is just another party's loss.  However we are eons away from that, for better or worse.  But what we ***really don't want*** -- with deflation pressing all around us again, creating a real need for monetary (not fiscal) stimulus to prevent the third ""Great"" bad thing -- is inflation paranoids running around trying to stop it screaming ""Weimar! Zimbabwe!  We're about to turn into another Weimar / Zimbabwe!""  Paranoia about inflation is absolutely destructive in this economy.   Yet, [Conservatives prefer socialism to 3% inflation](http://www.themoneyillusion.com/?p=14918), forgetting everything Milton Friedman taught them.  Alas, it's true." "Inflation as defined in the general, has many impacts at a personal level. For example, you say that the reduction in the price of oil has no impact on you.  That's absolutely not true, unless you're a hermit living off of the land.  Every box or can or jar of food you buy off the shelf of the grocery store has the price of oil baked into it, because it had to get there somehow.  High fuel costs for trucks mean increased costs to put food on shelves, which mean increased prices for that food. Even tobacco prices can affect you, because they affect what other people are spending.  Demand is always a significant factor in prices, particularly retail prices, and if people are spending more money on tobacco, they're probably spending less on other things - either buying less snacks, for example, or buying cheaper brands of those snacks.  So the price of Doritos may drop a bit (or not rise), for example. General inflation also tends to drive raises, particularly in industries with relatively small performance ties to raises.  If inflation is 3%, wages need to raise 3% or so in order to keep up, on average; even if your personal cost-of-living went up 0%, or 5%, or 10%, the default wage inflation will be closer to that of the national average.  Any raise less than national average is effectively a pay cut (which is one reason why inflation is needed in a healthy economy).  So your company probably has a cost-of-living raise everyone gets that's a bit less than inflation, and then good performers get a bump up to a bit more than inflation.  You can read more on this topic for a more in-depth explanation. Finally, inflation rates tend to be major factors in stock market movement.  Inflation that is too high, or too low, can lead to higher volatility; inflation that is ""right"" can lead to higher stability.  An economy that has consistently ""right"" inflation (around 2-3% typically) will tend to have more stable stock market in general, and thus more reliable returns from that market.  There are many other factors that lead to stock markets rising and falling, but inflation is one very relevant one, particularly if it's not in the ""right"" zone." "(Real) interest rates are so low because governments want people to use their money to improve the economy by spending or investing rather than saving. Their idea is that by consuming or investing you will help to create jobs that will employ people who will spend or invest their pay, and so on. If you want to keep this money for the future you don't want to spend it and interest rates make saving unrewarding therefore you ought to invest. That was the why, now the how. Inflation protected securities, mentioned in another answer, are the least risk way to do this. These are government guaranteed and very unlikely to default. On the other hand deflation will cause bigger problems for you and the returns will be pitiful compared with historical interest rates. So what else can be done? Investing in companies is one way of improving returns but risk starts to increase so you need to decide what risk profile is right for you.  Investing in companies does not mean having to put money into the stock market either directly or indirectly (through funds) although index tracker funds have good returns and low risk. The corporate bond market is lower risk for a lesser reward than the stock market but with better returns than current interest rates. Investment grade bonds are very low risk, especially in the current economic climate and there are exchange traded funds (ETFs) to diversify more risk away. Since you don't mention willingness to take risk or the kind of amounts that you have to save I've tried to give some low risk options beyond ""buy something inflation linked"" but you need to take care to understand the risks  of any product you buy or use, be they a bank account, TIPS, bond investments or whatever. Avoid anything that you don't fully understand." well it 2008 was six years ago, over time we would expect some price inflation. however it's only really a good thing for people who already own houses (it increases their net worth on paper) and people who want to sell, and move to a cheaper area.  If you aren't selling, it doesn't help you much.   If you're a young person trying to get into the housing market, it's obviously bad. A housing market where young people can't afford to get in is unhealthy. If you already own, and you want to move up and buy a bigger house, that's hard if no one is willing to buy your existing house.  I don't know why the govt is helping create a new bubble. But, if the underlying issues that caused the last crash are not fixed, well... the bigger the bubble, the bigger the pop. I don't understand your question. What the article is talking about is a bit more than circulating money indiscriminately. It is saying that by circulating more of it to rich and less to the poor will result in less growth overall, which I think we can all agree is a bad thing. The fed currently has interests rates pegged at all time historic lows. Why is this? To generate inflation. Our economy is currently, and has been for almost ten years, dangerously close to a deflationary spiral. Paying out pension funds will likely generate some inflation, but that is good. Taking away people's pension funds is theft. They worked for years to earn those pensions. If inflation halves the value of the dollar, getting some money is still far better than none at all. What you are asking is basically a combination of murder and theft in order to prevent something that we are trying to achieve; reasonable inflation.

There's a difference between physical currency and money (For example a bank may only hold only a small percentage of total deposits as cash that it's customers can withdraw).   I'm not sure which you're referring to, but either way you should read  about inflation.
