Money is just a unit of measure
Money is a way to exchange goods. It is a unit of measure, a very convenient unit of measure, but nothing more than that. It is the standardized unit by which people compare and exchange whatever they produce. When Google millionaires spend their money on a vacation in Hawai or going to a fancy restaurant; they really exchange their product, the search engine, with what a vacation rental company in Hawai offers them, or what the fancy restaurant company offers them. That is the real exchange going on between people; money is a convenient way to quantify these exchanges, and compare the relative values of these exchanges.
That you can somehow magically change people's productive powers, what products they make, by changing the units of measure, sounds bizarre to me. If the interest rates are low, there's no reason to believe that people will rush out tomorrow to pay higher prices for the same products. People are not that stupid, you know..they always are pushing to lower prices, not paying higher prices.
Just by changing a unit of measure and exchange you can't make people produce things which other people will find useful and will exchange their products for. i.e. you can't generate employment by playing around with interest rates, etc.
Instead of dollars and yuans, if we were to decide that sea shells were a unit of exchange, will you believe the sea shell makers and suppliers when they tell you that they can increase everyone's ability to produce the stuff they produce by changing the amount of sea shells which are used to circulate their products? You obviously wouldn't--then why would you believe a central bank can?
That the currency of a country is not that important is shown by the examples of Ecuador and Panama, who have adopted the US dollar as their currency. All goods in these countries are quoted in US dollars. Interest and loans are also in US dollars. The economies of these countries do just fine. If the USA in turn were to adopt the Chinese Yuan as its official currency, nothing would change; and trade between these two giant countries would be much more simplified.
A bank is nothing more than an intermediary between real lenders (savers) and real borrowers. It is limited in its loans by how much assets it has in the form of deposits by private individuals and corporations. A bank which lends more than it receives goes bankrupt, and takes the lenders down with it. This is true for a central bank as well, which is a bank of banks. The Fed reserve of the US can't generate loans out of thin air-it's balance sheet is open to the public and the loans are limited by it's assets. The stream of money coming into it, in the form of deposits, interest payments, etc. needs to balance with the stream going out of it, in the form of loans. If it lends more than it receives, it goes bankrupt, and takes the lenders down with it (as happened in Argentina and Greece).
The bankers obviously believe that they are the most important part of the system. But a farmer and a computer-maker has an equal right to claim that. No one sector of the economy can single-handedly improve the productive powers of other sectors. Not the least a sector which like sitting on their asses and watching noise like inflation, mounds of economic data which is really noise, and GDP growth, etc.
Don't expect the central banks or governments to help the country's employment numbers. Capitalists create employment, not people who run the currency of a country. They are claiming to have powers which they don't really have. Economics is not the science of money or interest rates or the banking system; it is the science of production of goods and their exchange.
In reality, the capital involved in buying and selling money, which is what the whole financial sector is, is taken away from the useful capital of society. Money, as Smith said, is the highway to assist in the exchange of goods (and services). Any capital going into building the highway or making it run more smoothly is a loss of capital from the other parts which produce goods and services. The financial sector of the S&P500 is about 10% of the index; and that should be excluded from economic activity. Same goes for GDP and other measurements; the earnings etc. of financial companies should be excluded from those measurements. Money is just in instrument to make the trading of goods and services easier-it in itself has no value. Central banks, financial companies, etc. are nothing more than aiders to economic activity. Just like the highways of a country are a small part of the overall capital, the monetary system, the banks and the money are a small part of the overall capital of the country.
Economists are often times seen talking about interest rates and monetary policy. I don't know how that came about, or when; but they have missed the most essential lesson of Smith-that money is just a means to facilitate trade, nothing else. Fussing over 0.25% interest rate increase or decreases is a joke.
Prudent borrowers and lenders decide the real rate of interest, not central banks
Interest rates are set by the borrowers-a central bank doesn't set them. The borrowers decide the interest rates of loans, not the banks or the lenders. In any economic transaction not done under duress, the buyers decide the price of what they purchase; sellers only make offers. Therefore, when we talk about market price of objects, in reality we are saying that these are the prices which buyers pay for these objects. The interest rate of a loan is also a price, and therefore we must realize that the borrowers are the ones in reality who decide the interest rates of the loan; the lenders only making offers. The borrowers can choose not to borrow at all if they don't want to. Prudent borrowers will not borrow even at low interest rates if they cannot employ capital successfully to make sure that they can return the bank the principal and the interest without problems. Similarly, prudent lenders will not loan at high interest rates to parties who are at risk of default. The loan market is primarily decided by prudent borrowers and prudent lenders. Banks are a part of the lenders side of this market. Note that the Government is also a borrower in most cases; and has a major role to play in deciding interest rates of money, which is why market rates are indexed to Government rates.
Central banks, banks and the financial system in reality follows the market (or borrowers, as explained above) in setting rates. They can't set the price at which people borrow-but it does make sense for them to follow the market rates. When rates are low, as they are currently (2016), it means that the demand for loans in the market is low-and that's why the interbank rates, fed funds rate. etc. are low. Not the other way around. When the market has high interest rates-the Fed fund rates, etc. will all go up together with it, as they should. Economics and Finance types have this essential causality backwards. The exception is under market stress-when the Federal reserve does come in as a lender of last resort (covered below). But for most of the time, the functioning of the large lender-borrower market is what decides the loans banks charge for money.
You pay more interest rate to borrow if your profits (of stock) are higher, or you expect a good stable earnings from the job you hold, or you believe that the rents you get from your real estate holdings will be good (the three groups of people in the Economy). Banks, including central banks do not manufacture money out of thin air-they are always tied down by the deposits and the payments they are receiving from mortgages, etc. to decide if they can loan more money to other borrowers. If they find that the project is too risky, they will not loan. The ones who do will go under, or lose a part of their loan. The interest rate on the loan is decided by the prudent borrowers-people who think that they can employ the money usefully, and have no problem returning the principal with interest of what they will borrow.
Interest rates are low at certain times like right now (in Japan, USA and Europe, 2016) because prudent borrowers do not want to borrow, because they don't see good returns for their capital in the future. The same goes for workers and people who live by rent. Even if a central bank or any other bank offers low rates of interest, if the people who want to take out the loan believe that they can't easily pay the interest AND the capital back, they will not take out the loan. The central bank and all banks follow the market-they lower rates in response to lower demands for loans, and increase them when market demand for loans is higher.
Even if you believe that a central bank could somehow lower rates, it doesn't follow that more loans will be emitted-because prudent buyers may feel that they can't even return the principle, let alone the interest, when they can't forecast their own returns or incomes well. In this sense money loans are very different from selling objects-while it is generally true that lowering the price of objects increase their demand, because money loans are a contract which runs into the future for the person who takes out the loan, and given that prudent buyers are the ones who are taking out loans, decreasing the price of money (interest) does not necessarily increase its demand, because unlike an object who you pay for right away and are done with, this involves substantial commitment on part of the borrower into the future, and they risk ruin and bankruptcy if they can't pay back the loan (principal and interest). Money loans are far more burdensome to the borrowers than buying an object outright-and that's why the assumption that offering lower interest rates leads to an increase in the number (and amount) of loans is incorrect. Even I used to believe this earlier; but I realized that money loans are contracts with strict terms for the borrowers, and are not simple objects being bought and sold in the marketplace. Comparing money loans to objects and their prices is therefore not right.
I continue where Adam Smith left us in 1776-most money is borrowed by prudent borrowers, and most money is loaned by prudent lenders and banks, who, are careful about their own well being, the classic self-interest of Adam Smith. Therefore, speculators and risky borrowers are bad for the banks as much as they are bad for themselves (they will get ruined and will take the bank principal down with it). If the bank is giving loans to the wrong people, regardless of whether the loan is made at high or low interest rates, it will go under itself. The principal itself might not be returned.
I must also point out that the notion of printing money to increase liquidity etc. is rather archaic. Most transactions today are carried out with bank transfers, check books, and credit cards; and the dollar amount of transactions carried about in a developed country like the US by pure cash, dollar bills, is probably less than 5%. Even for developing countries like India, Chile, China, etc. most transactions are non-cash, and you do not see people carrying wads of bank notes to buy houses and cars and other expensive objects. Smaller transactions are carried out by ATM cards and check books, and therefore the notion that central banks print money to increase money in the system is not true any more. Most money and money transactions are electronic nowadays in all developed and developing countries at least.
The jobless rate in the US, a silly number
These is a report published every month by BLS which is taken as the holy grail apparently for the Federal reserve to measure unemployment rate. The report shows that 95 million Americans above the age of 15 are unemployed at any point in time (in the month) and not even looking for a job. In the around 150 million people who are unemployed at any time, there are another 95 million who are not (it is called Participation rate)! This 95 million figure keeps changing too, and they publish that-it is 100 million sometimes, then 92 million, etc. etc. These are people taking temporary rest, out of job, working part time, traveling around, retiring, etc. etc. There is no reason to assume that there is a stable rate for this-i.e. Participation rate is not a constant, just another number thrown at the giant wall of data, and seeing what sticks. Most of the job report number fluctuations can be accounted for the flux between people who do not want to work for whatever reason, not because of interest rates, M2 money supply, etc. as the Federal Reserve wants you to believe. But the report ignores these details completely, because it has to come up with a nice number of around 5%...and obliges us with that. A large number of people do not want to have full time jobs in the US, and that is ignored by statistics experts like the BLS. The Fed in turn takes these numbers, and calling it data, talks about reducing it etc. Here's an article explaining the shortcomings of these report. and another one here. My point-the labor statistics are noise, joblessness is noise, and constantly changing, people don't work in a full time job for 5 years, then go back to work full time for 8 years, then go and travel and do nothing..all these things are not considered at all in the data! Garbage data put into a model of economy...
The biggest way to realize the bullshit data of the jobs report and unemployment rate is to think about the standard deviation of these numbers over time. A jobless rate of 2% to 10% is completely normal in my mind, it is the nature of things, and can't be attributed to one cause or another-knowing fully well that 37% of the adults call themselves unemployed at a particular time and we are okay with that!
Another big problem with the job reports is that it relies on surveys and then extrapolates. People lie in surveys, and there is no stable underlying distribution to think that surveys can be extrapolated. They may be statistically invalid procedures...two big ones this year (2016) when surveys got it wrong were that Britons wanted a Brexit and Americans wanted Trump to be president-survey data indicated that these things won't happen, but they did. This is a general problem with all surveys, as I have convered here.
GDP measurements are imperfect, and sometimes woefully inaccurate
From GDP measurements, which is another "data" published by a lot of so called economists who don't get the main part of economics, it seems that the Japanese GDP has been stuck at the same value since 1990 (to 2016, when I am writing this part of this post). According to GDP publishers and people who believe in that number, Japan, a developed nation of 120 million people, has not advanced at all on the last 26 years! Instead of accepting that maybe the GDP data is not capturing the progress of that wonderful country, they keep insisting that Japan really has gone nowhere in 26 years. I rest my case.
Interest rates, unemployment rate, GDP etc. are some very imperfect numbers, and they must not affect public policy too much. These are full of wrong information, as the Japan example shows. Another example is Venezuela; everything in South America knows that Venezuela is in a lot of trouble right now, people are forming lines to buy bread and milk, supermarkets, are empty etc. but the GDP per capita number of Venezuela is still published as a number above USD 10K. The country is in a lot of trouble, and anyone who follows news from Venezuela knows this, except the finance and economics types, who believe in some strange number and put Venezuela ahead of Peru and Colombia. A very large number of Venzuelans are immigrating every month to neighboring nations; and can testify that things are quite bad out there. Something like this is not reflected in the GDP per capital data at all.
Central banks have no influence on inflation rates
Central banks claims of controlling inflation rates are even more questionable. We must always remember what Smith said in WN-the real quantity of goods and products do not change with small changes in the amount of paper money circulating in the country. Paper money is just a highway to carry things around, to facilitate the exchange of goods and services. It is in itself not consumable, nor of any use.
Normal inflation measurements are very noisy, and most of the massive data taking going on today on inflation with ever changing inflation baskets is nothing but noise. See more about this on this blog post.
Original purpose of creating central banks was to provide a backstop, nothing else
Central banks were formed to prevent massive crises in the banking system. Note that the US Federal Reserve Act is of 1913, and even after that, there was the massive collapse of stocks and the so called Great Depression in 1929. Obviously they couldn't prevent that. More recently, the 2008 crash was not preventable by all the jargon of price stability, interest rate stability and increasing unemployment which the central bank is supposed to provide. What they do provide, is the security when the panic is on and full blowing. They are like firefighters-they do nothing most of the time, but when there is a fire, they will help society. That's how central banks were formed (previously, there were only private banks, who would all go bankrupt together, and the savers would lose their deposit). The FDIC guarantee is an extension of that-to reduce the probability of bank runs and savers losing deposits.
Let's not credit the firefighters for creating the world's tallest buildings and the subway lines. They are there when things go bad; but in reality are an expense when things are going good (They are the put seller on the financial system and savers deposits in the banks).
Everyone likes the guarantee of a central bank that their deposits are insured at least upto $200K or $250K. But beyond that, they can't do much. I know personally someone who still can't get $ 5 million they had with Lehman Brothers in 2008. Let's not give too much credit to the central banks in normal times-they really do nothing in those times. Once again, they are very useful in bad times, providing the market support which is necessary; but beyond that, having monthly meetings to set interest rates, looking at all kinds of noisy data like inflation, GDP, employments numbers etc. is a lot of hogwash. They pretend that they can do something about all these numbers; they can't.
Provide price stability is also in the original Fed Reserve Act of 1913. They readily discard the volatile food and energy prices to come up with a smooth inflation number-they promote price stability by discarding volatile data! Poor people spend a lot of money on food; and discarding food and energy costs is clearly not right. Note also that despite all intentions of price stability, prices of commodities, stock market values and people's savings and investments, real estate etc. crash all the time. Clearly they are not able to do much. You can always argue that it would be even worse if there was no central bank-and that's a completely valid argument-but in my opinion, you are giving too much weight to what a central bank can do. The central bank is a bank of banks, and all banks can do is transfer money from real savers to real borrowers-they cannot generate loans out of thin air, otherwise their balance sheets reflect it, and they go belly up. This happened in 2008 to many banks. And it has happened to the central bank as a whole in Venezuela-which is clearly bankrupt. Note that cash held in deposits is a liability for the bank, and the assets and interest payments on them must match these deposits-otherwise a bank, including a central bank like of Venezuela right now, is bankrupt (Assets less than liabilities, and not able to pay interest payments). This is the cause of devaluation of their currencies. The shenanigans of a bankrupt central bank don't last very long, just as the shenanigans of a bankrupt company or individual-soon people get a whiff of it and stop doing business with it. Most products in Venezuela are quoted in USD for this reason. Same with Argentina until recently, when Macri got elected and things seem to have stabilized a bit.
Bank of Japan is buying stocks in the Nikkei to "stimulate the economy and get growth back". See article here. They don't give up, do they? Their interest rate policy didnt get them anywhere for the part 20 years, so now they created another model-let's see if buying stocks creates growth and creates jobs. Banks can't do squat! Economic growth is decided by the hard working Japanese, the real capital owners of Japan, not a bank which is just in the business of transferring funds from lenders to borrowers. They will come up with newer and newer theories of tackling inflation, job growth, unemployment, etc...but will not accept that they have no effect over any of these things.
Here's what Smith said about operations of banking, and how they help us:
"It is not by augmenting the capital of the country, but by rendering a greater part of that capital active and productive than would otherwise be so, that the most judicious operations of banking can increase the industry of the country. "
