Price inflation is commonly thought to be caused by "too much money chasing too few goods." The general price level is indeed correlated with the money supply, but correlation should not be confused with causation. In a modern economy, prices are seldom driven by the money supply. More commonly, the money supply reacts to changes in the general price level.
Credit Money versus Commodity Money
It's easy to understand how the money supply can drive prices when a commodity like gold is used as money. In the gold rush days, California was basically on a barter system in which gold traded for goods and services. Gold was an asset for the holder and a liability for no one. As more gold was mined by private enterprise, monetary wealth in California increased. Indeed it increased much faster than the available supply of goods and services, so prices in terms of gold naturally rose.
Gold once comprised the monetary base, but today it is just another commodity. In a modern fiat money system, the monetary base is created by the central bank. However base money is a minor part of the money supply. Most of the money we use is credit issued by private banks in the form of deposits. Bank deposits are accepted as money because of the promise that they can be converted into base money on demand.
A bank loan increases the money supply but does not increase net wealth. The borrower receives a deposit that he can use as money, but he owes the bank that amount. Thus bank money behaves differently from base money. A bank can issue credit up to a prescribed multiple of its own capital. Within that constraint, the growth of bank money depends only on the demand from the public and the willingness of banks to lend. To understand what causes inflation today, we must therefore determine what creates the demand for credit.
Effects Related to the Price of Credit
The amount of bank money created is a function of many economic variables, including the price of credit which the central bank controls. The central bank can easily increase the price of credit enough to make borrowing unprofitable, stifle growth of the money supply, and even reduce total economic output. That would result in increased unemployment and possibly price deflation.
Conversely the central bank can easily reduce the price of credit, but the results are not symmetric. When the economy is operating well below capacity, cheaper credit will usually increase output without a significant increase in prices up to the point of nearly full employment. Thereafter the effects of cheap credit will generally lead to higher prices.
Demand for Credit and its Effects
The demand for credit arises mainly out of the desire to finance (1) new enterprise, (2) consumer spending, or (3) speculative investment. Let's briefly examine how each of these affects the money supply and prices.
- A new enterprise or an existing enterprise planning to expand production requires funds well ahead of the expected return from sales. New production is often financed with bank money, and the whole process has little effect on current prices. As the economy grows however, the amount of credit must grow in support. Indeed if credit were curtailed, the economy would stagnate for lack of adequate liquidity.
- Money borrowed for consumer purchases implies the availability of existing products whose prices have already been set by the sellers. Such borrowing increases the money supply without affecting those prices. However where supply falls short of demand, prices on consumer goods may rise, at least temporarily. But supply shortages tend to occur in isolated cases and are usually short-lived. They seldom have a lasting effect on the general price level.
- Money borrowed for speculative purposes mainly affects asset prices, particularly stocks and real estate. If the borrowing cost is set too low for an extended period, asset prices can become inflated. This creates a money illusion that can lead to a relaxed attitude by consumers toward higher prices, and result in an increase in the general price level.
Effects of Government Deficit Spending
Government deficit spending is normally financed by borrowing from the private sector. On balance, such borrowing and spending has no effect on the amount of base money, though it does increase the net financial wealth of the private sector in the form of Treasury securities. However contrary to conventional wisdom, there is no significant correlation between government deficit spending and price inflation.
If the government were unable to obtain funds through taxes or bond sales, it may resort to printing money to spend. If continued long enough, such spending would end in hyperinflation. This occurs infrequently and mainly as a result of serious corruption, revolution, or war. Hyperinflation is quite different in origin and character from the low level inflation that exists in most fiat money systems today.
A Case History - Inflation in the 1970s
During the 1970s, the US experienced a significant inflation in which the consumer price index rose at an annualized rate of 7.5%. However M1 rose relative to the real GDP at an annualized rate of about 3%. Clearly something besides an excess of transaction money drove that inflation.
A major factor was the roughly ten-fold increase in the price of oil resulting from two oil embargoes by OPEC. That led to a sharp increase in material costs in several important industries which had to be passed on as higher consumer prices. However that was not the only important cause of the inflation during the period.
Key industries were dominated by powerful corporations, some of which had the clout to set prices. This in turn enabled strong unions to gain generous wage contracts, sometimes well above the growth in labor productivity. Cost of Living Adjustments [COLAs] in the contracts added a positive feedback effect on wage growth. The benefits achieved by unions were mainly in the manufacturing sector, but gradually spread to the service sector.
With labor the main cost in most consumer items, the result was a cost-push inflation that became a serious wage-price spiral. Increasing wages helped enable consumers to absorb the rising prices imposed by producers. However these factors, together with the demands for expanding production, required a larger money supply to support it. As profit-seeking enterprises, banks were more than happy to lend to creditworthy borrowers, and so the money supply grew.
There are numerous forces that apply upward pressure to prices which are not driven by money supply growth. Global competition now limits the power of many domestic producers to set prices. But less competitive sectors still exist and contribute to a long term upward bias in prices. As prices rise, the money supply growth must necessarily keep pace.

Oh, that's what happened, eh?
I see no demand in any of these areas, for a long time to come.
And where demand exists, the banks are back to very tight criteria to qualify for credit, as it should be.
In a worldwide crunch, the consumer decides what they are willing to spend and for what. Right now the world's consumers are unwilling to add on debt.
They have seen their own wealth disappear, see no respite and are waiting to lose their jobs.
The Media Hype is 24/7. Politicians are Corrupt. Enron Madoff and the Idiot Governors from the Land of Lincoln, the stock market is also corrupt.
Good luck getting people to spend. IMHO

Markets do not overproduce commodities after the the initial run down period as they shut down their facilities and production to reduce the oversupply and that period in the past have been longer than our times. Markets are more integrated using information technology, the responses are rapid and periods are much shorter. Even the industries crashed and burnt very rapidly and many have already shut down their facilities.
So I wouldn't expect an oversupply period in future, because the prices are way too low to pay for any production as they deteriorated way too rapidly. Just look at oil, oil is selling way bellow the production costs of new wells within 2 months!. Who is going "dig dig dig" wells to sell oil bellow the cost.
Now whether inflationary period will a ahead of us would be related to recovery. If there is going to be recovery, there would be an inflation. The shut down facilities will only restart if the price is right. The more the prices go down the more inflationary the recovery will be.
I keep hoping, but want confirmation, that the govt is now financing by printing money, if the amount of money is deflating. That fits Keynesianism doesn't it? Another thing - doesn't this make Keynes a monetarist?

The m3 money(shadow statistics) supply is running close to 20%! The Treasury reserves are
being hoarded by banks in exchange for their toxic assets,
then being paid interest on them also. The Treasury is printing bonds(electronic)
and the Fed is buying them, like check-kiteing I think they call that, to drive down 30-yr mortgages. Once this
money is unleashed, I am sure it will fuel speculation. Oil will rise, I think $35
will remain support level. Dollar is key, a break of 79.50 should be watched for.
This massive intervention will backfire into speculative money, imo.

Gold also rose to $800 per ounce in 1980, and then died a slow death for 20+ years to a low of around $250 in 2003. The loss was much greater inflation adjusted.
Don't get me wrong, I like gold as a hedge investment and diversification. It's just that it doesn't produce income or growth.
Your dollar bill in 1935 was not an investment of any kind. Currency is to be spent, not held. Nobody claims currency is an investment that will even keep up with inflation.
But if you put that $1 in 1935 into the Dow Jones Industrial Average, it would be worth today about $59 plus you would have received dividends for the last 73 years. It would have bought a ton of bread over the years.
Gold bugs just don't get it. They come out of the woodwork in crisis times and spread their religion like zealots. Then the economy eventually recovers and gold languishes in price, just sitting on the shelf and producing nothing.

In the 1970s when oil prices quadrupled, M1 grew at its highest rate ever. I don't know how you can conclude "In NO nation did oil prices cause inflation when M1 was under control." M1 is created by the public itself. It simply reflects the amount of liquid assets needed to make payments. The Fed doesn't control M1. When prices rise, M1 normally rises too.

Assets like real estate, stocks, metals tread sideways while those resources humans must have to exist like food, water, energy trend higher.
Without easy credit and in fact fraudulent credit, luxury assets will experience a long painful sideways cycle. High end assets represent a big part of the growth engine from construction, services, lending, government taxes, and much more. More downside this coming year followed by years of sideways.
As posters have commented, that loaf of bread and gallon of gas will continue to go higher, so stagflation?
One way out is through wars or energy or technology. Examples are WWII, oil discoveries, internet and pc revolution. That next boom could be 5-10 years away. Maybe green technology - I wish I knew?
Societies depend on cheap resources to grow economies. History books document all the failed advanced cultures that failed without resources. Technology can create more resources via lower costs and advances extraction methods.
IMO we are going to have to wait for some dramatic event for the next real boom. Government actions are short term band-aids and the phony economy based on easy credit are over. World's resources are running low while populations are still increasing- not sustainable to economic growth in the long run. Less resources = less growth.
If a country is denied cheap and plentiful resources, it dies.
Ask the great tank commander "Erwin Rommel". Take away his gas and he's a failure. In the meantime the Patton's and Montgomery's plow forward.
Ask Robert E Lee on trying to win a war without resources.
Ask the natives of "Easter Island" about resources.
Ask late pre-WWII Japan about oil and resources.
So I am saying in a smaller way that the US culture was built on cheap oil. What happens in 5-10 years if "cheap" oil is really peaking? Again, financial gurus can come up with short term band-aids, but again they will eventually loose the war.
This oil issue will be back big in a couple of years, along with fresh water. Sustainability will be heard more frequently in 10 years. I don't see the next leap in growth without answers to sustainable "cheap" resourses. At some point the planet reaches it's limits on human growth and therefore government and corporate growth.
I'll be curious how places like Phoenix and Atlanta plan to deal with
water issues down the road. Maybe they pipe it from Canada?
The fundamental problem with a fiat, debt-based money system in a "Republic" of free citizens is that it gives too much control over the medium of exchange to so-called financial experts and the politicians who collude with them. Gold and silver may not be perfect (I happen to think they are, however, having arisen as an archetypal solution to the problem of exchange in a division of labor economy) but they are not interest-bearing, and once mined can be used over and over again to facilitate exchange. In a debt-based money system money is created when loans are made and destroyed when loans are paid back, after first subtracting off the interest which is recycled back into society as the purchasing power of the FIANANCIAL ELITE who have been legally empowered to do this legerdemain of money creation ex nihilo by the politicians, whom the financial elite reward of course. (By financial elite I do not mean the productive, rich people of the world, with whom I have no quarrel other than their poor taste and selfish tackiness, as at least in a free market they have provided something tangible to exchange and I am given the option to buy or not buy. My objection is with those who are given this immense power to control the market's money, and they are only given this power by governments willing to give it away.)
No thank you to fractional-reserve money systems anywhere, anytime. They are fundamentally dishonest and are designed to reward an elite for what is essentially a bookkeeping operation----a bookkeeping operation with devastating consequences to the world. This will be seen in the coming years when the derivatives tangle unwinds and our money is driven down to the point of worthlessness. Then there will be no arguments over the fine points of managing inflation. You don't argue fine points when someone is attempting to cut your throat.
At last I am reading a thorough monetary analysis on Seeking Alpha. While I think some of your statements are controversial, I think you have covered many areas accurately.
I would like to expand on your discussion of credit activity 3. (speculative borrowing). We have just gone through a period of speculative borrowing for something you did not specifically mention: the creation of additional financial paper. This had the effect of piling leverage on top of leverage for no other purpose than building a paper pyramid. This created illusory wealth and the mirage is now vanishing with the collapse of the pyramid. We might still have a severe recession had the same amount of debt been used to fund things of economic utility (means of production) because we would have created significant over capacities that would have to be worked off. At least the overcapacities would be in physical facilities that could be adapted to other uses. The only use for defaulted I.O.U.'s is to build an expensive fire.
A second area of comment is that many economists, including the oft quoted (in this comment stream) Milton Friedman, have proposed that a low level of inflation is the most conducive monetary condition to support economic expansion. Friedman proposed that an ideal monetary expansion would be 2-3% annually, and that would accompany a similar average inflation rate. I don't want to get into the argument here (but more on the subject below) of which is the cause and which is the effect. But I think all agree the two are correlated, whichever leads the other.
I agree with the concern of many that the current reflation attempts are creating a reservoir of balance sheet currency (bank reserves) that have the probable risk of exceeding the amount needed to stop a perceived potential deflationary spiral. This produces the very serious risk of that reservoir dam bursting at some point, flooding the streets with new liquidity that could create a money supply driven inflationary spike. This would require the return of a Paul Volker interest rate policy to slam on the monetary velocity brakes until the economy could adjust to the higher volume of currency. For this specific situation I have to disagree with the causation hypothesis of Mr. Hummel. This situation is one which could produce an inflationary spike where money supply was the cause and not demand for goods and services.
I do agree with Mr. Hummel that, in modern economies, supply and demand trade-offs drive price levels and monetary supply follows (quantity times velocity). That does not mean that money supply can not ever produce inflation.
A lot of the comment stream strikes me as having meritorous logic but some is lacking in continuity of thought across a logical minefield. Let me comment on some of the good points made.
GeorgeS - - - In your comment, the key concept is control. Where inflation takes hold, controlled expansion of money (again, amount times velocity) to meet but not exceed rising costs is difficult. In the 1979-1982 time period the control was exercized by throttling velocity.
Tesa - - - You make a valid point. I don't know why someone gave you a thumbs down. If the thumber reads this, perhaps he (she) could post again to let us learn the reasoning behind the vote.
gordon - - - Good points. I wanted to comment on $35 for oil. Very risky prediction - you might have to eat crow tomorrow. I really can't call a possible bottom here, but I'll share my strategy. I will start buying below $30 (if it happens) and back up the truck if $20 is broken. If we keep trading above $30, I may nibble but will not make a more significant commitment until there is a break-out above $45.
mohbull - - - You get it! Gold is a hedge, not an investment. Oil is an investment. These opinions go back to my commitment to economic utility.
acudoc - - - Most of the time the "Den of Charlatans" are merely reacting to interest rates driven by commerce and their primary function is to serve as a clearing house for transactions. On rare occasions, like now, they try to get ahead of the curve. (They haven't yet succeeded, by the way.) Because of their lack of experience in being proactive, we all get nervous about how well they will help or how much they will damage the outcome.
(Not just the FED's ability to counterfeit.)
The printing press is not the answer. The American people need to return to the basics of being an industrialized nation which would sustain local employment and we need to be freed from government interference of private enterprize. Once the incentive to be creative and produce is gone, there's is nothing left. Remove the dream and the hope, and its over!
It's sad that this error is repeated endlessly. In reality most production and corporate investment is funded by retained earnings (profits). It must be so, else debt would balloon endlessly and capital lost -- which is exactly what happened at GM.
Likewise bank lending to consumers, except in the narrow case of funding big ticket purchases by creditworthy customers with adequate security, must not be expanded beyond prudent conservation of bank capital and liquid reserves. It's absurd that banks gave unsecured credit to anyone who could make interest-only minimum payments.
Hummel is an apologist for unpayable Federal debt, bankrupt states, failing banks, and HELOC helots.
www.banque-france.fr/g... . I think this comment thread has fallen into the trap that many of these inflation discussions seem to end up. What are the defintions of inflation, deflation, and money? If one argues that inflation is a rise in prices and I argue that inflation is an increase in money and credit then we are talking apples and oranges. and the discussion is almost pointless.
Any form of real stimulus must have a corresponding creation of productive goods or services. TARP and fed money dumps are critically lacking in real valuable expansion of goods and services and the corresponding rise in employment and economic stability the world needs.
A trillion dollars without any goods or services is 100% worthless to people besides the ones who got it. This is just a redistribution of wealth from you to someone else. And you thought welfare was expensive. Welfare for rich people is 10,000x more expensive.
