You are mixing concepts. GDP measures all of the value created. Profit measures value captured by the banks above their costs. If banks operate on a 10% gross profit margin, that profit number means banks are consuming 1%/10%=10% of the world GDP. If true, that would be an enormous cost, and I can easily see the opportunity for optimization that cryptocurrency advocates talk about.

Bank costs are things like loans being defaulted on, which is good for society (lending is risky, and interest from loans that pay back covers defaults). The profit is the amount the banks make that isn't consumed by those costs, so that's the right number to use.

Let's take a look at wells fargo. https://www.marketwatch.com/investing/stock/wfc/financials https://www.marketwatch.com/investing/stock/wfc/financials Interest income: 53.66B Interest expense: 5.91B Net interest: 47.75B Net income: 21.94B so already, we're working off of closer to 40% net margin. Now let's look at what actually causes the difference between those numbers: >10.08B in taxes Pretax is 32.12B, so there's about 15B left to explain This turns out, roughly, to be the difference between Non-Interest Income and Non-Interest Expense - in other words, stuff that isn't really related to regular banking stuff. I'm not going to repeat this analysis for another 1000 banks, but it seems like, at best, you might double that number if you decide that some of these expenses aren't needed.

GDP doesn't measure value created; it measures money spent. If I hire you to dig a big hole and then fill it in, GDP rises but no value was created. Also if I pay you $50 to pay me $50, GDP rises by $100.

  Are you arguing all entertainment costs are wasteful? If I hire you to act in a TV show and then stream it to a million people, would you also say no value is created? What is value, if not what makes people happy / gives them utility? If someone is willing to pay someone to dig a hole, then that digging gives them value (assuming no fraud/ etc).
