Verification means contacting the originator, and asking if they actually authorized the transfer. That means two jumps per leg; one each way... and also verification time (1-64 hours assuming a "normal" workweek).
And this is where I feel you go off the rails according to my professional expeience.
You assume that any financial institution will only have first heard of a transaction when the person benefitting from the tranaction arrives to put a call on the funds...
This is wrong and has been since the days of paper ledgers!
While there have been significant failuers when organizations and regulators do not follow their own rules, there are huge hosts of agencies and organizations that track and record all activities.
Case in point from one of the most recent and spectacular failures...Bernard Madoff.
When you call a broker to buy or sell a financial instrument(Stock, Bond, etc...) they create a transaction record and tie all of their communciations to that.
They then call their middle market brokerage and a new record is made there as they begin the process of placing their action on the actual market.
Large organizations may skip that step and place their offers directly into the market through the clearing structures built in to their corporation...where that second record is created as the deal changes hands between in-house subsidiaries.
Finally, the deal appears on the market itself and a participants in the market see it. Someone on the other side of the coin accepts the price offered or demanded and a deal is agreed on. This is recorded by both sides in a new common record which can be sent to the next level.
No matter the auditors and other structural organizations that get this data at this level, the deal is not yet done. The deal must be executed. This is the level I worked at.
Once the deal is executed, by one of a very few top level organizations in any financial market, it is finally done and funds and assets change ownership.
So how did Madoff do it? By creating a legitimate business and then making up numbers that looked real for fake transactions hidden behind a wall of real activity. By then using knowlege of the regulatory systems he used to manage and his reputation and fiends to keep the data from beeing looked at...
But it was all there. And the slowly growing number of people who were loknig at it were screaming at the SEC for years.
So why does this mean you are wrong? Because no significant financial system can functino without a huge amount of checks and balances behind it. Every day, all financial organziations report ALL of their dealing with their main regional HQ. They also have entire departments who's after market hours job it is to organize transactions into "books", where each book tracks transactions to one specific partner.
All of this is then traded with the partner in questino to make sure that all parties got the deal information correct and to resolve "broken deals" where one side or the other is in error.
In addition, all this is sent to government regulators and the core market operators(NASDAC, NYSE, Etc..)
Every night, EVERYONE checks their books so that they know where all the prics and assets are for the next day's trading.
All this is transmitted globally
As was worked out here, this data is transmitted, from any tech above 6, on the xboat routes every 4 hours.
So by the time your traveller has been told they has the loan they applied for two days ago, that data ahs already been broadcast to the x-network and is ALREADY in jump.
By the time that traeller gets to their ship and makes their leasurely way out to the 100d limit, that information has been beamed at light spedd to an xboat which has jumpped.
by the time the traveller's ship arrives at its destination, the xboat has arrived before it and the data was broadcast to a financial data clearing house on world.
And by the time your traveller goes to pick up their cash at the east bank of Nowhere, that data has been detailed, listed and stacked in data retrival so that when the bank calls the on-world clearing house, they need only look up the data by account number and confirm the transaction from pretransmitted data.
And this is the "Short" description of a process that can fill not just books but libraries.
Granted, the further off the xboat route you get, the more of a delay you will encounter. But that is directly in relation to the drop in tech and big ticket items. You are not going to get that kind of service at a Tl 3 backwater but you are also not going to be paying that starport to build you a ship either! Any large trasaction likely to occur there is likely to be attended by bonafide representitives of those involved in the deal. Any deals will be from credit pre-agreed on and established by those representatives, their credentials and the documentation they bring with them.
Just as it has been done ever since we developed a banking system that was not based on you carrying this letter form me to my cousin Samuel in Venice...
So please, understand that there is a lot more to a credit transaction than you putting cash in an account and then writing a check elsewhere and everyone expecting it to work out....
