             | What do I do? I have this guy who wants to lend in 2024 and

             | slightly off balance, but don't interest rates basically
             | move up and down together? Let's do it and deal with the

             | It's also something I know well, as I know a lot of
             | farmers.
             | 
             | 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

               | 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

             | 
             | Let me offer a (partial) defense of crypto if I can:
             | 
             | Broadly, crypto is divided into crypto-currencies and
             | applications.
             | 
             | Let's tackled currencies first, some of which some are
             | reputable and some of which are grifts, but which viewed in
             | their most favorable light attempt to be a form of currency
             | or asset that is decentralized. This means that no single
             | party may unilateraly devalue them, or restrict their trade
             | in any way.
             | 
             | (No I understand if that doesn't excite a lot of people,
             | but this is clearly valued by some people!)
             | 
             | As may be obvious, crypto-currencies are too volatile to
             | serve as actual "currencies", so they are at best "assets".
             | But it is possible to use these assets as collateral for
             | the minting of stablecoins. I'm not sure this is quite risk
             | transfer, but it essentially relies on the willingness of
             | some to hold speculative assets to enable the creation of a
             | stable assets.
             | 
             | In turn, these assets are not typically useless -- they
             | hold value because there is demand for them to pay for
             | transaction costs on blockchain.
             | 
             | Blockchains themselves are not useless. We may not think
             | much of the difficulties of transferring money, but it is a
             | real challenge in LARGE swaths of the world, where people
             | are unbanked or live under tyrannical governments. I would
             | argue that even in the west, the need becomes is becoming
             | more pressing (Trudeau freezing trucker supporter bank
             | accounts, banks imposing tons of restriction on cash
             | withdrawals and "large" bank transfers).
             | 
             | Beyond transfer, they also serve to run decentralized
             | applications. People are quick to dismiss those, and true
             | it doesn't enable to do anything dazzingly new. It simply
             | enables you to do things you could already do, but in a way
             | where no single party (or even colluding parties) can shut
             | it down. This may seem silly, but I think the world would
             | truly be better if we for instance had a YouTube where
             | copyright trolls couldn't strike down / demonetize legimate
             | content.
             | 
             | Applications then. In reality, we're still far from
             | decentralized YouTube (but we will get there). Most
             | applications today are financial. And I think they're quite
             | useful. The financial infrastructure being built is
             | genuinely novel and useful.
             | 
             | The problem is that it is navel-gazing at the moment: that
             | infrastructure is mostly used to perform financial
             | operations on crypto tokens themselves. But there is no
             | reason that they couldn't be used for other assets.
             | 
             | In fact this is starting to happen: you can now invest in
             | real estate and US treasuries on the blockchain. We're
             | still a way from mainstream adoption, and that has mostly
             | to do with legal uncertainties that prevents established
             | players from diving in (though many of them are
             | experimenting). There are also entrenched interests there,
             | it must be said.
             | 
             | So if anything else, crypto helps build a better financial
             | infrastructure.

           | and its ability to adapt to changing circumstances.
           | 
           | Not all centrally planned economies are doomed to failure;
           | some have been quite successful, notably in East Asia where

           | including a rigid class structure, the influence of the
           | Church, and the lack of certain technological innovations.
           | Ascribing the issues of a historical period mainly to its
           | economic structure oversimplifies the multitude of factors
           | that influenced societal development.
           | 
           | Moreover, while financial markets do help in transmitting
           | information from consumers to producers, they are not
           | infallible. They can, and often do, suffer from issues like
           | information asymmetry, where one party in a transaction has
           | more or better information than the other. This can lead to
           | problems like adverse selection and moral hazard. Financial
           | markets can also be subject to speculation, which can distort
