Banking is a core activity in the economy and in financial markets, receiving deposits, making loans and investing. Banking supports immediate and future business activities and basic consumer needs of housing, vehicles and education. The banking system has evolved through the disintermediation of the 1970s, the S&L crisis of the 1980s, the housing implosion of the Great Recession and the zero-interest-rate-policy of the 2000s. Higher interest rates have bolstered banks in the past. But the recent rapid rise in rates along with technology-enhanced money transfers revealed new risks from an old source. A review of trends in banking can provide perspective for economic activity and investing ahead.
