         | Interesting observation given that your own wealth is managed
         | this way.
         | 
         | Whether its the simple bank deposit in a checking account, if
         | you've ever chased an interest rate for a savings account, or
         | had your earnings managed in a retirement account from your
         | employer, or if you attempted to make money faster because a
         | debt was coming due.
         | 
         | Its all tied together and a product of this system.
         | 
         | The goal is to keep money moving within the economy, as people
         | also race to hoard it.

         | 
         | Either way it's hardly a waste of time or money, and banks make
         | money not from "arbitrage shell games" but by matching buyers

         | The output (generally speaking, not specific to money markets)
         | is better prices. There are large scale examples of economies
         | in which prices were mismanaged either due to lack of
         | information/technology or centrally planned prices, some of
         | which resulted in failed states (e.g. Venezuela and the Soviet
         | Union). While providing market information signals via prices
         | is certainly an abstract concept that most people will never
         | appreciate, it is important regardless.
         | 
         | For complex instruments in money markets, the main effects are
         | bridging mis-priced treasuries on different time frames and
         | hedging against various outcomes for pensions, banks, and
         | dealers in physical commodities.
         | 
         | Most of the complex stuff either serves one of those purposes
         | or becomes a zero sum game that doesn't affect non-
         | participants. It's important to judge each instrument by its
         | purpose and mechanism rather than bunch everything as a way to
         | make bankers richer (e.g. a future vs. a CDO).

             | 
             | It benefits people who have cash that they want to invest,
             | because they have more opportunities to do it and more
             | visibility over which investments are safe and which ones
             | are risky.
             | 
             | Therefore it benefits society by transferring cash from

             | you do ultimately need to believe, to some extent, in the

             | to think it's perfect, or that it shouldn't be regulated,

             | accept that it is the system we use. In a totally state-

             |

             | go, study the factors that make wheat more profitable to
             | corn, do their predictions of what will be the case at the

               | I'm not sure why I'm being downvoted, as I didn't think

               | now, and consequently much smaller. "I'm a super smart 18

               | presumably its recent explosion in size has brought some
               | additional value, but it's very hard to believe that

             | Let's imagine that a commercial farmer, whom we'll call
             | Jeremy plants 100 acres of wheat on a farm. Market values
             | for wheat (and everything else you can farm, from livestock
             | to grains and so on) vary and move constantly, as a
             | function of supply and demand. We saw this in an extreme
             | form with the invasion of the Ukraine, and the droughts in
             | Italy last year.
             | 
             | Now the problem with farming is your timescales are long
             | compared to the movements of values for your product in the
             | market, so you've no real idea as to what what you're
             | planting will be worth by the time the bloody thing has
             | actually grown and you've got it harvested and into barns
             | to be sold. And once the seed is in the ground, you can't
             | exactly just plough it all over and plant something else
             | (not strictly accurate, but you don't want to go down that
             | route).
             | 
             | So now let's fast forward. Jeremy now harvests his wheat,
             | and let's say the price has moved up a lot between planting
             | and harvest. Jeremy is a happy man, who's going to have a
             | bumper time, even if his crop doesn't produce as much per
             | acre as he might like at the minute, because it's not
             | raining enough. Or conditions are perfect, and the price
             | has gone up, and he makes a huge amount and can reinvest.
             | Jeremy is a happy camper.
             | 
             | However, if the price falls, Jeremy is not going to be
             | quite so chipper. As such, Jeremy can move his risk,
             | through the use of a hedge. Let's say Jeremy hunts around
             | to find someone to buy his wheat at the start of the
             | season. He might sign a contract with a flour producer,
             | stating that they will promise to buy x tonnes of his grain
             | at PSy per tonne. Jeremy now has a fixed price, which has
             | hedged his risk profile. Now his risk has moved from
             | financial to productive - he has to be able to provide the
             | x tonnes. If he can't produce it all on the farm, he needs
             | to source the difference. On the other hand, if he's a good
             | farmer, and the farm produces well, and he doesn't over-
             | extend his risk on what he's committing to, he now has a
             | fixed price contract for his goods, _which isn 't going to
             | fluctuate based on time_ (assuming the contract is honoured
             | - if he's worried about that, Jeremy could then buy
             | insurance on the risk of a default on the contract, but
             | that then gets complex). This is a very good thing, but
             | means if the market prices his wheat vastly higher than he
             | expected, he'll miss out on that upside.
             | 
             | This is called a forward contract. There's other types of
             | contract which can be used to do similar things (futures,
             | derivatives...) but that gets a bit more complex.

               | 
               | Simple example - let's say the contract is for 100 tonnes
               | of wheat at PS175 a tonne. So Jeremy should get PS17,500
               | for the wheat he's contracted to deliver. Now let's say

               | merchant can't/won't pay up. Maybe he's in financial

               | But for whatever reason, he refuses to pay.
               | 
               | Now let's also imagine two scenarios - one in which the
               | price of wheat has gone up, and one where it's gone down.
               | In the former, Jeremy is actually happy with this, as he
               | can now sell his grain on the open market for more than
               | the contract, and claim the insurance payout on the
               | contract. On the other hand, if the price went down,
               | Jeremy still has to sell his grain, but he might only get
               | PS100 a tonne, which is going to result in a loss of
               | PS7,500. At this point Jeremy is very glad of the
               | insurance.
               | 
               | Now the interesting bit is the insurer has the estimate
               | the risk of default, and the likely movement on the
               | market, to be able to offer a sensible insurance product
               | to Jeremy. So Jeremy might pay PS1,000 for an insurance
               | product which pays out PS10,000 on the default of the
               | purchaser, for example. Obviously the numbers involved

               | tonne, which is probably around the mark given at the

         | You ask "Where is the productive output of all these arbitrage
         | shell games?", which is a very fair question. The purpose of
         | financial markets, sometimes but not always wholly achieved, is
         | to transfer risks to those best able to hold them. E.g., you
         | are not the optimal person to hold the risk that, through no
         | fault of your own, your house burns down. That risk exists, and
         | you are not the optimal holder of it. Hence insurance. A
         | Lincolnshire farmer -- and yes, I like the non-abstract solidly
         | of the example -- is not the optimal holder of the 'risk' that
         | the Australian and Kansas wheat harvests are super-bountiful.
         | Markets allow that risk to be transferred to a non-farmer
         | better able to hold the risk.
         | 
         | Of course, with markets come some 'unproductive' stuff.
         | Likewise, democracy is good, but that is not necessarily
         | praising the optimality of all parts of campaign finance
         | legislation.

         | Let me also mention that I am the author of the definitive
         | reference book on old Vintage Port: Port Vintages (and
         | seemingly the board disallows a link).

         | "How do you produce the things that your population needs, in
         | the quantity and at the time they need them, as efficiently as
         | possible?" This is why every centrally-planned economy
         | eventually fails, and why we were stuck in the feudal middle
         | ages for a millennia. Information (and _incentives_ ) about
         | what to produce and how to produce it efficiently weren't
         | getting to the population at large, which caught us in a local
         | subsistence minima. Financial markets give all the players an
         | incentive (in the form of profit) to transmit information (in
         | the form of prices) from people who want goods to people who
         | can supply them.
         | 
         | This is also behind the theory of why certain forms of
         | financial transactions are legal and others are illegal.
         | Arbitrage = legal, because it converges prices in two separate
         | markets in a way that gives producers in both those markets
         | better information about true demand. Futures markets = legal,
         | because they smooth out temporal fluctuations in demand so that
         | producers only have to worry about producing, while also
         | incentivizing the construction of just enough storage &
         | buffering to hold that product. Pump & dump schemes = illegal,
         | because they distort price information in the market in an
         | unsustainable way and then leave later participants to bear the
         | cost of this. Same with Ponzi schemes. Equities markets =
         | legal, because they transmit information about the overall cost
         | of capital within the economy to firms, which can then use it
         | to decide the profitability or unprofitability of various
         | investments.
