How do wire transfers get settled?
Wire transfers normally run through either the Fedwire system or the Clearing House Interbank Payments System (CHIPS). The process generally works like this: You approach a bank or other financial institution and ask to transfer money. You give the bank a certain code, either an international bank account number or one of several other standards, which informs the bank where to send the money.  The bank sends a message through a system like Fedwire to the receiving bank, along with settlement instructions.  This is where the process can get a bit tricky. For the wire transfer to work, the banks must have reciprocal accounts with each other, or the sending bank must send the money to a bank that does have such an account with the receiver. If the sending bank sends the money to a third-party bank, the transaction is settled between them, and the money is then sent to the receiving bank from the third-party bank. This last transaction may be a wire transfer, ACH transfer, etc.  The Federal Reserve fits into this because many banks hold accounts for this purpose with the Federal Reserve. This allows them to use the Fed as the third-party bank referred to above. Interestingly enough, this is one of the significant ways in which the Fed makes a profit, because it, along with every other bank and routing agent in the process, collects a miniscule fee on this process.  You'll often find sources that state that Fedwire is only for transferring large transactions; while this is technically correct, it's important to understand that financial institutions don't settle every wire transfer or payment immediately. Although the orders are put in immediately, the financial institutions settle their transactions in bulk at the end of the business day, and even then they normally only settle the difference. So, if Chase owes Bank of America $1M, and Bank of America owes Chase $750K, they don't send these as two transactions; Chase simply credits BAC $250K.  You didn't specifically ask about ACH transfers, which as littleadv pointed out, are different from wire transfers, but since ACH transfers can often form a part of the whole process, I'll explain that process too. ACH is a payment processing system that works through the Federal Reserve system, among others. The Federal Reserve (through the Fedline and FedACH systems) is by far the largest payment processor.  The physical cash itself isn't transferred; in simple terms, the money is transferred through the ACH system between the accounts each bank maintains at the Federal Reserve.  Here is a simple example of how the process works (I'm summarizing the example from Wikipedia). Let's say that Bob has an account with Chase and wants to get his paycheck from his employer, Stack Exchange, directly deposited into this account. Assume that Stack Exchange uses Bank of America as their bank.  Bob, the receiver, fills out a direct deposit authorization form and gives it to his employer, called the originator. Once the originator has the authorization, they create an entry with an Originating Depository Financial Institution, which acts as a middleman between a payment processor (like the Federal Reserve) and the originator. The ODFI ensures that the transaction complies with the relevant regulations. In this example, Bank of America is the ODFI.  Bank of America (the ODFI) converts the transaction request into an ACH entry and submits it, through an ACH operator, to the Receiving Depository Financial Institution (RDFI), which in this case is Chase bank. Chase credits (deposits) the paycheck in Bob's account.  The Federal Reserve fits into all of this in several ways. Through systems like Fedline and FedACH, the Fed acts as an ACH operator, and the banks themselves also maintain accounts at the Federal Reserve, so it's the institution that actually performs the settling of accounts between banks.
frostbank.com is the closest thing I've found, so accepting this (my own) answer :) EDIT: editing from my comment earlier: frostbank.com has free incoming international wires, so that's a partial solution. I confirmed this works by depositing $1 (no min deposit requirement) and wiring $100 from a non-US bank. Worked great, no fees, and ACH'd it to my main back, no problems/fees. No outgoing international wires, alas. I would certainly hope to make the transfer by wire - the prospect of   popping cross the border with several million dollars in the trunk   seems... ill fated. I suppose I'm asking what sort of taxes, duties,   fees, limits, &c. would apply Taxes - None. It is your money, and you can transfer it as you wish. You pay taxes on the income, not on the fact of having money. Reporting - yes, there's going to be reporting. You'll report the origin of the money, and whether all the applicable taxes have been paid. This is for the government to avoid money laundering. But you're going to pay all the taxes, so for transfer - you'll just need to report (and maybe, for such an amount, actually show the tax returns  to the bank). Fees - shop around. Fees differ, like any other product/service costs on the marketplace. Because a wire transfer requires the individual bank to bank process, it is usually more expensive than an automated clearing house, which requires minimal involvement by individuals at financial institutions. Many ACH transactions come with only a small fee, or even no fee at all, since they are run with more efficiency. However, if you want a better guarantee that your money will arrive on time, it might be worth it to pay the wire transfer fee. With both cases, it is possible for errors to be made. However, since you often get to review the information before it is sent with a wire transfer, the method is a little more secure. Also, because identities are verified with wire transfers that take place between bank accounts, there is less chance of fraud. Wire transfers that take place between financial institutions are generally considered quite secure. from http://www.depositaccounts.com/blog/difference-between-wire-transfer-and-ach.html "As far as I understand, OP seems to be literally asking: ""why, regarding the various contracts on various exchanges (CBE, etc), is it that in some cases they are 'cash settled' and in some 'physically settled' -?"" The answer is only that ""the exchange in question happens to offer it that way."" Note that it's utterly commonplace for contracts to be settled out physically, and happens in the billions as a daily matter.  Conversely zillions in ""cash settled"" contracts play out each day.  Both are totally commonplace. Different businesses or entities or traders would use the two ""varieties"" for sundry reasons. The different exchanges offer the different varieties, ultimately I guess because they happen to think that niche will be profitable.  There's no ""galactic council"" or something that enforces which mode of settlement is available on a given offering - ! Recall that ""a given futures contracts market"" is nothing more than a product offered by a certain exchange company (just like Burger King sells different products). I believe in another aspect of the question, OP is asking basically:  ""Why is there not, a futures contract, of the mini or micro variety for extremely small amounts, of currency futures, which, is 'physically' settled rather than cash settled ..?"" If that's the question the answer is just ""whatever, nobody's done it yet"".  (Or, it may well exist.  But it seems extremely unlikely?  ""physically"" settled currencies futures are for entities operating in the zillions.) Sorry if the question was misunderstood." "Securities clearing and settlement is a complex topic - you can start by browsing relevant Wikipedia articles, and (given sufficient quantities of masochism and strong coffee) progress to entire technical books. You're correct - modern trade settlement systems are electronic and heavily streamlined.  However, you're never going to see people hand over assets until they're sure that payment has cleared - given current payment systems, that means the fastest settlement time is going to be the next business day (so-called T+1 settlement), which is what's seen for heavily standardized instruments like standard options and government debt securities. Stocks present bigger obstacles.  First, the seller has to locate the asset being sold & make sure they have clear title to it... which is tougher than it might seem, given the layers of abstraction/virtualization involved in the chain of ownership & custody, complicated in particular by ""rehypothecation"" involved in stock borrowing/lending for short sales... especially since stock borrow/lending record-keeping tends to be somewhat slipshod (cf. periodic uproar about ""naked shorting"" and ""failure to deliver""). Second, the seller has to determine what exactly it is that they have sold... which, again, can be tougher than it might seem.  You see, stocks are subject to all kinds of corporate actions (e.g. cash distributions, spin-offs, splits, liquidations, delistings...)  A particular topic of keen interest is who exactly is entitled to large cash distributions - the buyer or the seller?  Depending on the cutoff date (the ""ex-dividend date""), the seller may need to deliver to the buyer just the shares of stock, or the shares plus a big chunk of cash - a significant difference in settlement.  Determining the precise ex-dividend date (and so what exactly are the assets to be settled) can sometimes be very difficult... it's usually T-2, except in the case of large distributions, which are usually T+1, unless the regulatory authority has neglected to declare an ex-dividend date, in which case it defaults to standard DTC payment policy (i.e. T-2)... I've been involved in a few situations where the brokers involved were clueless, and full settlement of ""due bills"" for cash distributions to the buyer took several months of hard arguing. So yeah, the brokers want a little time to get their records in order and settle the trade correctly." "If wire transfer through your bank does not work then perhaps one of the more popular money transfer services may be what you are looking for such as MoneyGram or Western Union. Now these rely on a trusted ""registered"" third party to do the money transfer so you need to make sure that you are working with a legitimate broker. Each money transfer service has a site that allows you to perform the search on registered parties around your area. There are certain fees that are sometimes applied due to the amount being transferred. All of these you will want to do some detailed research on before you make the transfer so that you do not get scammed.   I would suggest doing a lot of research and asking people that you trust to recommend a trusted broker.  I have not personally used the services, but doing a quick search brought many options with different competitive conversion rates as well as fees. Good luck." As Nathan has correctly noted, ACH processes transactions in daily batches. The reason for that is accounting - the money doesn't actually change hands for each transaction. All the transactions are aggregated and calculated in the batch process, and the money only changes hands for the difference. Consider this: If each transaction was to be handled separately, each time banks would have to adjust their books to account for the money movement. But if we do it in batch we have this: The resulting inter-bank transfers: Total for the original 30 transactions - 2 transactions between the banks: A->B and C->A. If you need money to be transferred immediately (relatively) - you can use wire transfer. Some banks will still aggregate and batch-process those, but more than once a day. They'll charge you additional fee for their inconvenience. "For most banks this is not the case.  Transfers within the bank are usually instantaneous. It is not uncommon for banks to draw out the length of transactions because while the money is ""transferring"" or ""settling"" it is actually sitting on the bank's balance sheet, being lent out but not earning any interest.  A good deal for them when you aggregate over the millions of customers they have.  Your bank may be trying to squeeze a few pennies of interest out of you. Delays in transactions also allow their fraud team the flexibility to investigate transactions if they want to. Normally they probably don't but if the bank delays all transactions, then those being investigated will not be aware of it." I'm not sure I understand what you're trying to say, but in general its pretty simple: She goes to the UK bank and requests a wire transfer, providing your details as a recipient. You then go to your bank, fill the necessary forms for the money-laundaring regulations, you probably also need to pay the taxes on the money to the IRS, and then you have it. If you have 1 million dollars (or is it pounds?), I'm sure you can afford spending several hundreds for a tax attorney to make sure your liabilities are reduced to minimum. from what I learnt in au and limited to au banking system ( very much like other western countries), banks settle their transfers ( inter banks) 4pm afternoon. Those transactions are like everyday between accounts, person to person, person to vendor(not credit cards), vendors  to vendors( small businesses) etc. as for large transactions banks use check accounts( yes banks themselves have check account for each other). Check accounts are settled in three business days( ex public holidays). When large business deal with large business, they use debentures and corporate bonds which is a business IOU and using banks as mediate to settle. IOUs have up to 60 days settle periods.  Some complications unique to au banking system.  There are only 4 large banks in au and they and their subsidiaries own 99% of the assets collectively. What gets more interesting is large 4 banks owns each other. Each banks holds significant amount shares of other banks. They are like 4 brothers with different surnames. All of it is to minimise risk and share profit. Being into Business since years and having clients worldwide I receive a lot of payments via wire transfers. Some in business and some in personal checking accounts. I have never been charged by my bank for any incoming wire. And by the way I bank with HSBC and BoA in the US. Actually the charges on the account depends on the type of account you are opening/holding with the bank. With a tight competition in the finance and banking industry you can always demand the bank for the services you want and the pricing you want. The best thing to do is ask your bank if they can wave those incoming wire charges for you and if not you have a whole bunch of options. A lot of questions, but all it boils down to is: . Banks usually perform T+1 net settlements, also called Global Netting, as opposed to real-time gross settlements.  That means they promise the counterparty the money at some point in the future (within the next few business days, see delivery versus payment) and collect all transactions of that kind. For this example say, they will have a net outflow of 10M USD.  The next day they will purchase 10M USD on the FX market and hand it over to the global netter.  Note that this might be more than one transaction, especially because the sums are usually larger. Another Indian bank might have a 10M USD inflow, they too will use the FX market, selling 10M USD for INR, probably picking a different time to the first bank.  So the rates will most likely differ (apart from the obvious bid/ask difference). The dollar rate they charge you is an average of their rate achieved when buying the USD, plus some commission for their forex brokerage, plus probably some fee for the service (accessing the global netting system isn't free). The fees should be clearly (and separately) stated on your bank statement, and so should be the FX rate. Back to the second example: Obviously since it's a different bank handing over INRs or USDs (or if it was your own bank, they would have internally netted the incoming USDs with the outgoing USDs) the rate will be different, but it's still a once a day transaction.  From the INRs you get they will subtract the average FX achieved rate, the FX commissions and again the service fee for the global netting.  The fees alone mean that the USD/INR sell rate is different from the buy rate. A handful of well-known banks in the United States are part of the clearXchange network, which allows customers of those banks to move money amongst them. The clearXchange service is rebranded differently by each member bank. For example, Chase calls it QuickPay, while Wells Fargo calls it SurePay, and Capital One calls it P2P Payments.  To use clearXchange, the sender's bank must be part of the network. The recipient isn't required to be in the network, though if they are it makes things easier, as no setup is required on the recipient's end in that case. Otherwise, they must sign up on the clearXchange site directly. From what I can tell, most payments are fee-free within the network. I have repeating payments set up with Chase's QuickPay, and they do not charge fees. There are several ways to minimize the international wire transfer fees: Transfer less frequently and larger amounts. The fees are usually flat, so transferring larger amounts lowers the fee percentage. 3% is a lot. In big banks, receiving is usually ~$15. If you transfer $1000 at a time, its 1.5%, if you transfer $10000 - it's much less, accordingly. If you have the time - have them send you checks (in US dollars) instead of wire transferring. It will be on hold for some time (up to a couple of weeks maybe), but will be totally free for you. I know that many banks have either free send and/or receive. I know that ETrade provides this service for free. My credit union provides if for free based on the relationship level, I have a mortgage with them now, so I don't pay any fees at all, including for wire transfer. Consider other options, like Western Union. Those may cost more for the sender (not necessarily though), but will be free for the receiver. You can get the money in cash, or checks, which you can just deposit on your regular bank account. For smaller amounts, it should be much cheaper than wire transfer, for example - sending $500 to India costs $10, while wire transfer is $30. "I looked this up on Wikipedia, and was hoping the answer would be ""no - stores cannot refuse legal tender"", but unfortunately, it's not the case!  If the retailer wants to go to the lengths of refusing certain denominations to protect themselves from counterfeit currency, they are fully within their rights to do so. The ""Legal Tender"" page on Wikipedia says this about Canadian bills: [...] Retailers in Canada may refuse bank notes without breaking the law. According to legal guidelines, the method of payment has to be mutually agreed upon by the parties involved with the transactions. For example, convenience stores may refuse $100 bank notes if they feel that would put them at risk of being counterfeit victims [...] What is interesting about what I found out, is that legal tender cannot be refused if it is in repayment of an existing debt (i.e. not a store transaction for which there existed no previous debt).  So you could offload your $100 bills when repaying your Sears credit card account (or pay in pennies if you wanted to!) and they couldn't refuse you!"
