Firstly, I say that it is anachronistic for the government (including its organs such as the Bank of England) to lend money at a lower interest rate than it borrows. This is a fairly simple point - if you need to borrow, why do you lend at a lower rate? A bank will borrow from the Bank of England at a certain rate and lend to others at a higher rate - the difference between the two rates being its profit margin. Now, regardless of whether or not it is the same people buying gilts as it is borrowing at the BofE base rate, what they are doing when they lend at the base rate is putting money into the private-sector system and what they are doing when they issue gilts is taking it back out again.
It is as if the BofE were begging banks to make profit-making loans - to be banks - and were prepared to pay banks to do it if necessary. To me, this is an anachronistic situation
There's a lot of conflation and misunderstanding in this post, so not really sure where to start (my response has pretty much turned into an essay, so have split it up a bit to hopefully make it more bearable/readable)
Introduction
There seems to be a fundamental misunderstanding by yourself as to the mechanics and functioning of both central banks and commercial banks and also the relationship between the two. In addition there's also a misunderstanding as to the relationship between the activities of the central bank in managing the money supply and the activities of the treasury in borrowing to fund the functioning of the state. I'll try and unpick the various strands, but the murkiness of the conflation (and indeed the topic itself) makes any explanation/response to your post a bit long winded, a headfuck to explain, and likely to veer away from the original point of contention in order to illuminate the backdrop to it. However as marx once said
there is no royal road to science, and only those who do not dread the fatiguing climb of its steep paths have a chance of gaining its luminous summits.
Relationship between commercial banks & central banks - generic overview
Firstly, the element of 'borrowing' (the reason for the inverted commas will become apparent further on) from central banks by commercial banks is a tiny fraction of both the overall funding of commercial banks and the assets that they are used to fund. This is a basic axiom of money supply in capitalist society, i.e. a small amount of central bank money (effectively one of the narrowest measure of money - issued notes and reserve balance between banks and central banks) forms the base of the system then, via fractional reserve lending and the general circulation of money/loans/money like instruments, that small base of money is grossed up massively and the resultant grossed up money and money like equivalents all then forms wider the means of circulation (and payment) within society. Now there's nothing magic or conspiratorial about this process, it's just a function of the fact that money circulates.
Your post above seems to imply that you think commerial banks 'borrow' from the central bank and then lend on to other parties and that is a fundamental basis of their activities. In reality (and somewhat counter intuitvely) instead of a commercial bank having a net liability to the central bank (i.e. represting what it has 'borrowed') it almost always has a net asset with the central bank. Central bank 'lending' to commercial banks is done on a 'lender of last resort' basis - and as well as forming a tiny part of a commercial bank's funding, it is also always done on a really short term and sporadic basis, i.e overnight funding etc. and most of the time banks don't like to use it as it has a certain stigma attached to it (a sign of weakness in the bank's ability to borrow on the open markets etc..).
Granted in times of crisis and seizing up of the domestic & international money markets, central bank funding in the UK is relied upon more, and banks would crumble without it, however this is a temporary phenomena with the end of 2008 seeing the biggest spike in this, which has since disipated. This means that, your assertion that the central bank 'lends' to commercial banks at the base rate and then the commercial banks lend that money on to other parties at higher rates doesn't really hold true.
Relationship between commericial banks & central banks - specific example
It may be easier to demonstrate my point by looking at an example of an individual commericial bank and it's interactions/transactions with the central bank.
We can use RBS for this purpose. Now although it's effectively govt owned it's financial accounts are prepared on the basis of RBS being a distinct separate group, so we can use these to look at the borrowing & lending between RBS and the Central bank, and also place that in context of the overall assets & liabilities of the individual bank (i.e. RBS). So first of all, if we look at page 270 of RBS's
accounts which shows its balance sheet - and look at the asset section - we can see at the end of 2010 it had total assets of £1,453bn. The bulk of these assets consist, as you'd expect, of loans, debt/equity securties and derivatives. Now this 1.45 trillion of assets needs to be funded by something, and looking at the liabilities section of the balance sheet on the same page, we see that this funding is mainly made up of deposits by banks & customers, debt & equity securities issued, and derivatives.
The question now is how much of the banks 1.45 trillion of assets is 'funded' in the way you suggest it is, i.e. by borrowing from central bank. Well if we then go to page 384, there is a table which shows what element of these 1.45 trillion of assets & liabilities relate to assets & liabilities with the UK state. The first column of this table shows assets/liabilities with central govt, which includes the central bank. Looking at this we can see at the end of 2010 there is 147 million of 'borrowing' from the central bank (we can ignore the rest of the liabilities in this column as these do not relate to transactions with the central bank). So out of RBS's 1.45 trillion of liabilites that funds its 1.45 trillion of assets only 147million is 'funded' by the central bank - this represents about 0.01% of its total assets/liabilities.
But this is only part of the story. If you look at the assets section of that same table, we see that RBS also has 18.8bn of balances with the central bank, i.e. money which the central bank owes to RBS. So on a net basis, instead of having a net borrowing from the central bank (as your assertion states it should), it actually has a net lending to the central bank of around 18.7bn. The reason why this balance is the reverse of what you thought it should be (and the reverse of what it intuitevly should be), is partly due to the way the central bank controls the money supply through it's open market operations and partly because commercial banks always hold a certain level of money with the central bank for stability purposes (on which they only receive a tiny rate of interest). The only exception to this picture was at the end of 2008 at the depths of the crisis, if you look at the same numbers on the table on page 384 for 2008, you see the inverse of what I've descibed above, i.e a net borrowing from the central bank of around 26.1bn - this was during the depth of the crisis when money markets were completely shut and the lender of last resort principle kicked in. As you can see however from 2009 onwards this was not the case. So why is that then?
Why do commercial banks have an overall asset with, rather than a liability to, central banks
The reason as to why commercial banks end up having an asset with, rather than a liability to, the central bank - is down to the mechanics of the way the bank manages the money supply and money creation (something that I've noted you seemed to have a poor understanding off previosuly). This process is called open market operations - and again perhaps somewhat counter intuitevely, the mechanics of the process is exactly the same as quantative easing, the only difference is the reason for doing it - i.e. it's done on a much smaller basis and it's purpose is to manage short term interest rates via the supply of base money in the economy.
So if the central bank decides it wants to inject more money into the economy - there are two steps that happens, firstly it creates money by a touch of a key stroke (the modern equivalent of the printing press) - it then uses that created money to purchase or repo from the commerical banks securities or other financial instruments. This is how the money enters the economy, i.e. not through the central bank lending to commerical banks, but by the central bank purchasing (or repoing) assets from commericial banks with money that it's created. The net impact on the central bank's balance sheet is an asset representing the security it has purchased and a liability representing the amount it 'owes' to the commercial bank for that purchase. This liability of the central bank represents, from the commercial banks point of view, an asset, money on account/deposit with the central bank (i.e. the equivalent of the 18.7bn we saw on page 384 of RBS's accounts) , which can then be used as money to do other things with (lend, invest etc..). To the extent that it just sits on deposit with the central bank however it earns next to no interest (and following QE in the last year or so, a lot of the money that was introduced into the economy endep up straight back on deposit with the central bank, due to fears about lending into the wider money system etc..)
