National central banks, such as the Federal Reserve in the United States or the European Central Bank, are responsible for implementing monetary policy and regulating the banking system within their respective countries. They also often hold the country's foreign exchange reserves and act as the lender of last resort to commercial banks. In contrast, commercial banks primarily focus on providing financial services to individuals and businesses, such as accepting deposits, making loans, and facilitating payments. While both types of banks play a crucial role in the financial system, national central banks have a broader mandate and are typically owned or controlled by the government. **

Banks are classified into different categories based on their functions and operations. The main classifications of banks include commercial banks, which provide a wide range of financial services to individuals and businesses; investment banks, which focus on raising capital for companies and providing advisory services for mergers and acquisitions; central banks, which are responsible for regulating the country's monetary policy and issuing currency; and retail banks, which primarily serve individual customers and offer services such as savings accounts, loans, and mortgages. Additionally, there are also cooperative banks, which are owned and operated by their members, and online banks, which operate primarily through digital platforms. **

No, banks cannot physically print money. Only central banks, such as the Federal Reserve in the United States, have the authority to physically print money. However, commercial banks can create money through the process of fractional reserve banking, where they are able to lend out more money than they actually hold in reserves. This process allows banks to effectively create money in the form of loans and deposits. **

Wirecard was financed by several major banks, including Commerzbank, ABN Amro, and ING. These banks provided loans and credit facilities to Wirecard, allowing the company to expand its operations and invest in technology. However, after the accounting scandal in 2020, these banks faced scrutiny for their involvement in financing Wirecard's questionable activities. **

Banks are considered tangible companies in the sense that they have physical locations, employees, and assets such as buildings and equipment. However, a significant portion of a bank's operations are conducted digitally, making them increasingly intangible in terms of their services and transactions. Overall, banks can be seen as a combination of tangible and intangible elements, with their physical presence and digital capabilities both playing important roles in their operations. **

The decision to nationalize banks is a complex one that depends on various factors such as the country's economic situation, regulatory framework, and the specific goals of the government. Nationalizing banks can provide more control over the financial sector, ensure stability, and prevent systemic risks. However, it can also lead to inefficiencies, lack of competition, and political interference. Ultimately, the decision to nationalize banks should be carefully considered and weighed against the potential benefits and drawbacks. **

Banks primarily live on the interest they earn from the loans they provide to customers. When customers take out loans, they pay interest on the amount borrowed, which is a major source of income for banks. Additionally, banks also earn money through fees charged for various services, such as account maintenance fees, overdraft fees, and ATM fees. These sources of income allow banks to generate revenue and continue operating. **
