Why does money value normally decrease?
"Your house doesn't need to multiply in order to earn a return. Your house can provide shelter. That is not money, but is an economic good and can also save you money (if you would otherwise pay rent). This is the primary form of return on the investment for many houses. It is similar for other large capital investments - like industrial robots, washing machines, or automobiles. The value of money depends on: As long as the size and velocity of the money supply changes about as much as the overall economic activity changes, everything is pretty much good. A little more and you will see the money lose value (inflation); a little less and the money will gain value (deflation).  As long as the value of inflation or deflation remains very low, the specifics matter relatively little. Prices (including wages, the price of work) do a good job of adjusting when there is inflation or deflation. The main problem is that people tend to use money as a unit of account, e.g. you owe $100,000 on your mortgage, I have $500 in the bank. Changing the value of those numbers makes it really hard to plan for the future! Imagine if prices and wages fell in half: it would be twice as hard to pay off your mortgage. Or if the bank expected massive inflation in the future: they would want to charge you a lot more interest! Presently, inflation is the norm because the government entities, who help adjust how much money there will be (through monetary policy - interest rates and the like - ask about it if you're interested), will generally gradually increase the supply of money a little bit more quickly than the economy in general. They may also be worried that outright deflation over the long term will lead to people postponing purchases (to get more for their money later), harming overall economic activity, so they tend to err on the slightly positive side. The value of money, however, has not really ""ordinarily decreased"" until the modern era (the 1930s or so). During much of history, a relatively low fixed amount of valuable commodities (gold) served as money. When the economy grew, and the same amount of money represented more economic activity, the money became more valuable, and deflation ensued. This could have the unfortunate effect of deterring investment, because rich jerks with lots of money could see their riches increase just by holding on to those riches instead of doing anything productive with them. And changes in the supply of gold wreaked havoc with the money supply whenever there was some event like a gold rush: Because precious metals were at the base of the monetary   system, rushes increased the money supply which resulted in inflation.   Soaring gold output from the California and Australia gold rushes is   linked with a thirty percent increase in wholesale prices between 1850   and 1855. Likewise, right at the end of the nineteenth century a surge   in gold production reversed a decades-long deflationary trend and is   often credited with aiding indebted farmers and helping to end the   Populist Party’s strength and its call for a bimetallic (gold and   silver) money standard. -- The California Gold Rush Today, there is way too little gold production to represent all the growth in world economic activity - but we don't have a gold standard anymore, so gold is valuable on its own merits, because people want to buy it using money, and its price is free to fluctuate. When it gets more valuable, and people pay more for it, mines will go through more effort to locate, extract and refine it because it will be more profitable. That's how most commodities work. For more information on these tidbits of history, some in-depth articles on:" You expect interest because you forgo the opportunity of using the money as well as the risk of losing the money if the borrower can not pay you back.  This is true also with gold - you would expect interest if you loaned someone your gold for a time period. When you deposit your money in the bank you are loaning your money to the bank who then loans the money to others.  This is how the bank is able to pay interest on your accounts. "You get paid interest on deposits because banks only keep a fraction of the deposits on-hand. The rest is put to other uses, such as loaning money to others. If you deposit money and yield 1% interest, the bank is able to fund an auto loan, at 5%. By saving, you are actually making more capital available in the marketplace. ""Fixed"" or ""durable"" assets like gold, real property, or durable goods are different -- their value is based on attributes such as demand (gold, oil) or location (real property). If you bought an apartment in Manhattan in 1975, it appreciated greatly in value over the course of 30 years... but it did so because demand for apartments in New York City grew, while the supply of apartments grew more slowly. The government prints money for two core reasons: Think of it this way: Money is valuable because it is money." The reason is governments print extra money to cause inflation (hopefully reasonable) so that people don't just sit comfortably but do something to make money work. Thus inflation is an artificial measure which leads to money value gradually decreasing and causing people invest money in one way or another to beat inflation or maybe even gain some more money. Printing money is super cheap unlike producing any kind of commodity and that makes money different from commodities - commodities have their inherent value, but money has only nominal value, it's an artificial government-controlled product. It is in circles. Today Money is fiat money. From economic stand point a moderate inflation is good. It there is near zero inflation or deflation, then economy would come to standstill and would stagnate. Hence everything has to becomes expensive. This keeps the economy in motion. House or Gold does increase in value otherwise one would not have purchased them. If you are saying on buying a house, you keep it with someone and after a period of time you get one extra room or keep an ounce of gold and after some years it becomes 2 ounce, well it does increase but differently. There reason there aren't many such schemes is because quantifying it is difficult. It would normally fetch more money than one had bought it for. "Currently, the quantity theory of money is widely accepted as an accurate model of inflation in the long run. Consequently, there is now broad agreement among economists that in the long run, the inflation rate is essentially dependent on the growth rate of money supply. However, in the short and medium term inflation may be affected by supply and demand pressures in the economy, and influenced by the relative elasticity of wages, prices and interest rates - Wikipedia: Inflation causes You also asked ""can you give any reference that explains that this [encouraging people to work] is one of the reasons government prints money?"" See the list of positive effects of inflation in that article."
Imagine that your normal mode of using credit gets you a score of X. As time goes by your score trends upward if the positive items (length of credit) outweigh your negative items. But there are no big increases or decrease in your score. Then you make a one time change to how you use credit. If this is a event that helps your score, there will be a increase in your score. If it is bad thing your score will drop. But if you go back to your standard method of operating your score will drift back to the previous range. Getting a car loan for a few months to get a bump in your credit score, will not sustain your score at the new level indefinitely. Overtime the impact will lessen, and the score will return your your normal range. Spending money on the loan just to buy a temporary higher credit score is throwing away money. An economy produces goods and services and people use money to pay for those goods and services.  Money has value because people believe that they can buy and sell goods and services with it in that economy. How much the value of money is, is determined by how much money there is in comparison to goods and services (supply and demand). In most economies it is the job of the federal/national reserve bank to ensure that prices stay stable (ie the relationship of goods and services to how much money there is is stable); as this is necessary for a well running economy.  The federal reserve bank does so by making more (printing, decreasing interest rates) or less (increasing interest rates) available to the economy. To determine how much money needs to be in the economy to keep prices stable is incredibly hard as many factors have an impact: If the reserve bank gets it wrong and there is more money compared to goods and services than previous, prices will rise to compensate; this is inflation If it's the other way round is deflation. Since it is commonly regarded that deflation is much more destabilizing to an economy than inflation the reserve banks tend to err on the side of inflation. yield on a Treasury bond increases This primarily happens when the government increases interest rates or there is too much money floating around and the government wants to suck out money from the economy, this is the first step not the other way around. The most recent case was Fed buying up bonds and hence releasing money in to the economy so companies and people start investing to push the economy on the growth path.  Banks normally base their interest rates on the Treasury bonds, which they use as a reference rate because of the probability of 0 default. As mortgage is a long term investment, so they follow the long duration bonds issued by the Fed. They than put a premium on the money lent out for taking that extra risk. So when the governments are trying to suck out money, there is a dearth of free flowing money and hence you pay more premium to borrow because supply is less demand is more, demand will eventually decrease but not in the short run. Why do banks increase the rates they loan money at when people sell bonds? Not people per se, but primarily the central bank in a country i.e. Fed in US. Your best bet is probably to limit the amount of money in the account. If there is never more in there than he would normally spend in a month, that limits the losses. I am curious why he writes cheques. Most people I know write only a few a year. Simply having another person hold the chequebook for him, and bring it to him when it's needed, wouldn't be a big deal for the people I know. Say he pays bills twice a month and needs it then, fine, but why does he need it when he's just going for a walk? But if this would be an argument then just move most of the money into an account he can't write cheques against, and put each month's expenses into the chequing account each month. During the hyperinflation of the Wiermer republic, corporate stocks and convertible bonds were thought second only to the species (gold, silver etc) as the only secure currencies.  As Milton Friedman proved, inflation is caused solely by the monetary token supply increasing faster than productivity.  In the past, days of species of currency, it was caused by governments debasing the currency e.g. streatching the same amount of silver in 50 coins to 100 coins. Sudden increases in the supply of precious metals can also trigger it. The various gold rushes in 19th century and later, improvements in extraction methods caused bouts of inflation. Most famously, the huge amounts of silver the Spanish extracted from the New World mines, devastated the European economy with high inflation. Governments use inflation as a form of stealth flat tax. Money functions as an Abstract Universal Trade Good and it obeys all the rules of supply and demand. If the supply of money goes up suddenly, then its value drops in relation to real goods and service. But that drop in value doesn't occur instantly, the increased quality of tokens has to percolate through the market before the value changes.  So, the first institution to spend the infalted/debased currency can get the full current value from trade. The second gets slightly less, the third even less and so on. In 2008, the Federal reserve began printing money and loaning at 0% to insolvent backs who then used that money to buy T-Bill. This had the duel effect of giving the banks an (arbitrary) A1 rated asset for their fractional reserve while the Federal government got full pre-inflation value of the money paid for the T-bills. As the government spent that money, the number of tokens increased fast than the economy.  In times of inflation, the value of money per unit drops as its supply increases and increases The best hedges against inflation are real assets e.g. land, equipment, stocks (ownership of real assets) and convertible bonds which are convertible to stock.  It's important to remember that money is, of itself, worthless. It's just a technology that abstracts and smilies trading which at the base, is still a barter system. During inflation the barter value of money plunges owing to increased supply. But the direct barter value between any two real assets remain the same because their supplies have not changed.  The value of stocks and convertible bonds is maintained by the economic activity of the company whose ownership they represent. Dividends, stock prices and bond equity, as measured in the inflated currency continue to rise in sync with inflation. Thus they preserve the original value of the money paid for them. Not sure why you expect more inflation. The only institution that can create inflation in the US is the Federal Reserve which Trump has no direct control off. Deregulation of banks won't cause inflation in and of itself as the private banks cannot alter the money supply. If banks fail, owing to deregulation, unlikely I think given the dismal nearly century long record of regulation to date, then the Federal Reserve might fix the problem with another inflation tax, but otherwise not. "Many people assume that if the price of something is $10 and they have 1,000 of that thing, they should expect to be able to sell them for something around $10,000.  Such an assumption may hold much of the time, but it doesn't always.  Worse, the cases where it fails to hold are often those where it would be relied upon most heavily.  Such an assumption should thus be considered dangerous. In a liquid market, the quantity of a something that people would be willing to buy at something close to the market price will be large relative to the quantity that people would seek to sell in the short term.  If at some moment in time one person in the market was willing to immediately buy 500 shares at $9.98 and another was willing to immediately buy 750 at $9.97, someone seeking to sell 1,000 shares could immediately receive $997.50 for them (selling 500 to the first person and 500 to the second, who would then be ready to buy 250 more from the first person who was willing to sell for $9.97).  Such behavior would be in line with what many people's assumptions. In an illiquid market, however, the quantity of something that people would be willing to buy near market price could be surprisingly low.  This is more often a problem in the marketplace of things like collectibles than of stocks, but the same thing can happen in the stock market.  If there's one potential buyer for a stock who thinks it's overpriced but has potential and would be worth $9.50, but that person only has $950 to spend, and nobody else thinks the stock would be worth more than $0.02/share, then until people sold a total of 100 shares the price would be $9.50, but after that the price would drop instantly to $0.02.  There would be no ""cushioning"" of the fall.  If the person with 1,000 shares was first in line, he'd get to sell 100 shares for $950 to the aforementioned seller, but would be unable to get more than $18 for the remaining 900. A major danger with markets is that markets which are perceived as liquid attract people to the buying side, while those which are seen as illiquid repel people.  The danger in the latter is obvious (having people flee a seemingly-illiquid market will reduce its liquidity further) but the former is just as bad.  Having people flock to a market because of its perceived liquidity will increase its liquidity, but can also create a ""false price floor"", causing demand to appear much stronger than it actually is.  Unless real demand increases to match the false price floor, the people who buy at the higher price will never be able to recoup their investment." Yes.  When the currency of a country appreciates, it benefits some groups and disadvantages others.  In particular, exporters suffer when a currency increases in value relative to other countries.  In a country like the US, where exporters are small relative to the economy, this isn't a big deal.  In germany, where exporters make up a big part of the economy, a currency increasing in value leads to large numbers of layoffs and other negative net effects to the economy. So, this isn't always the case, but in the example provided the option is most likely in the money or near the money since the delta is nearly 1 - indicating that a $1 move in the underlying results in a $0.92 move in the option - this will happen when the expiration is very far out or the option is in the money. As expiration gets closer, movements in the underlying become more pronounced in the options because the probability of the stock price moving from its current position is lower.    As the probability of the stock price moving goes down, the delta of in the money options approaches 100, eventually reaching 100 at expiration. Another way to word this is that the premium on in the money options shrinks as expiration approaches and the intrinsic value of the option increases as percentage of total value so that movements in the underlying stock price become a greater influence on the option price - hence a greater delta. Again, if the option is out of the money, this is not the case.
