Silicon Valley Bank and the Fragility of Banking
Silicon Valley Bank Overview
Event Timeline:
March 8, 2023: Silicon Valley Bank (SVB) was reported to be financially sound, with assets exceeding 200 billion and deposits over 175 billion. This apparent stability masked underlying vulnerabilities related to its asset-liability management.
March 10, 2023: SVB experienced a rapid failure and was subsequently taken over by the Federal Deposit Insurance Corporation (FDIC). This collapse highlighted critical risks in the banking sector, particularly concerning interest rate sensitivity and deposit concentration, sending shocks through the financial system and prompting concerns about systemic risk.
Significance of Banks
Crucial Economic Role: Banks are indispensable agents in the economy, facilitating a wide array of economic activities.
They serve as financial intermediaries, connecting savers with borrowers by channeling funds from those with surplus capital to those needing investment.
Key functions include creating credit through lending, operating the payment system, and allocating capital inefficiently throughout the economy.
Inherent Risks and Supervision: Despite their vital role, banks inherently carry risks such as liquidity risk, credit risk, and interest rate risk which, if unchecked, can lead to systemic instability.
This necessitates robust government supervision of the banking system by entities like the Federal Reserve and the FDIC to safeguard financial stability, protect depositors, and prevent financial crises that could destabilize the entire macroeconomic landscape.

Understanding Money
Definition of Money: Money is broadly defined as any asset that is generally and readily accepted by people for the purchase of goods and services, or for the repayment of debts.
Asset: In an economic context, an asset is anything of value owned by an individual or a firm that can be used to produce future economic benefits. Money is a particularly liquid asset.
Role of Money: Money plays a transformative role in economic development by overcoming the inefficiencies of barter.
It significantly reduces transaction costs, thereby facilitating trade and specialization.
Specialization: By allowing individuals and firms to focus on producing what they do best, and then using money to exchange for other goods and services, money enables a far greater division of labor, leading to increased productivity and overall economic growth.
14.1 What Is Money, and Why Do We Need It?
Bartering Before Money: Prior to the advent of money, economic exchanges relied on bartering—the direct exchange of one good or service for another.
This system was highly inefficient primarily because it necessitated a double coincidence of wants, meaning both parties involved in a trade must simultaneously desire what the other possesses. This significantly complicated and limited trade, hindering economic expansion.
Commodity Money: As societies evolved, they transitioned to using commodity money, which consists of objects with intrinsic value that also serve as a medium of exchange (e.g., animal skins, salt, precious metals like gold and silver).
This form of money made trade easier than pure barter, but issues like divisibility, durability, and portability still posed challenges.
The eventual transition to fiat money (money without intrinsic value, declared legal tender by government decree) further enhanced efficiency due to its portability, divisibility, and stable supply management.
Functions of Money: Money performs four critical functions in an economy:
Medium of Exchange: This is money's primary function, as it is widely accepted for transactions, eliminating the need for a double coincidence of wants inherent in barter systems.
Unit of Account: Money provides a common measure of value, allowing for easy comparison of the relative worth of different goods, services, and assets. This simplifies economic calculations and decision-making.
Store of Value: Money allows individuals to defer consumption by holding wealth in a liquid form that can be easily exchanged for goods and services in the future. While other assets can also store value, money's liquidity makes it particularly convenient.
Standard of Deferred Payment: Money facilitates transactions that involve future payments, such as loans and contracts. Its expected stability of future value is crucial for the efficient operation of credit markets and long-term financial planning. Significant inflation or deflation undermines this function.
14.2 How Is Money Measured in the United States Today?
Definitions of Money Supply: Economists use different measures of the money supply to capture varying degrees of liquidity. These measures help policymakers gauge the amount of money circulating in the economy and formulate monetary policy.
M1 (Narrow Money): This is the most liquid measure of the money supply, including:
Currency in Circulation: Physical cash (paper money and coins) held by the public, excluding currency held by banks.
Checking Account Deposits (Demand Deposits): Funds held in checking accounts, which are readily accessible for transactions.
Traveler's Checks: (Historically significant, now rarely used).
M2 (Broad Money): This broader measure includes all components of M1 plus other less liquid assets that can be easily converted into cash or checking deposits. M2 accounts for:
M1 components
Small-Denomination Time Deposits: Certificates of Deposit (CDs) with balances less than 100,000.
Savings Deposits: Funds held in savings accounts.
Noninstitutional Money Market Fund Shares: Funds invested in short-term government securities and other money market instruments, typically accessible for withdrawal.
U.S. Money Supply Statistics: The U.S. dollar is a dominant global currency. Consequently, U.S. currency holdings are significantly higher than in many other countries, partly due to the substantial use of U.S. dollars abroad as a safe haven or unofficial currency in other economies. This global demand affects the domestic money supply and seigniorage revenues for the U.S. government.
14.3 The Role of Banks in the Economy
Banks' Functions: Commercial banks are central to the monetary system, playing a unique role in money creation.
They don't just act as passive intermediaries; they actively create loanable funds and, thus, money, through the process of accepting deposits and making loans. The total amount of money held in checking accounts within the banking system can exceed the actual currency in circulation due to fractional reserve banking.
Banks primarily aim to make profits by earning interest on borrowed funds and by investing in various financial instruments, balancing risk and return.
Bank Balance Sheet: A bank's balance sheet provides a snapshot of its financial position, detailing its assets (what it owns) and liabilities (what it owes).
Assets (examples): Total assets represent the uses of funds by the bank.
Reserves: Cash held by the bank in its vault or on deposit at the Federal Reserve. (135 billion in this example).
Loans: Funds lent to individuals and businesses, representing the largest asset category for most banks, generating interest income. (900 billion).
Securities: Investments in government bonds and other marketable financial assets. (700 billion).
Liabilities (examples): Total liabilities represent the sources of funds for the bank.
Deposits: Funds placed in checking, savings, and time accounts by customers, forming the largest liability for most banks. (1,000 billion).
Short-Term Borrowing: Funds borrowed from other banks, financial markets, or the Federal Reserve through its discount window. (400 billion).
Reserves: Banks are typically required to hold a certain fraction of their deposits as reserves.
Historically, these required reserves served as a primary tool for the Federal Reserve to control the money supply.
However, in March 2020, the Fed set the required reserve ratio to 0 \% for all depository institutions. This change, while allowing banks greater flexibility in lending, shifted the Fed's primary tool for managing monetary policy from reserve requirements to interest on excess reserves and open market operations.
Do Banks Create Money?
T-Accounts Explanation: The concept of money creation by banks can be clearly demonstrated using T-accounts, which are simplified balance sheets that show changes in a bank's assets and liabilities due to a transaction. For example:
When a customer deposits 1,000 cash, the bank's cash reserves (an asset) increase by 1,000, and its demand deposits (a liability) also increase by 1,000.
If the required reserve ratio is 10 \%, the bank must keep 100 in reserves but can lend out 900.
When the bank makes a loan of 900, its loans (an asset) increase by 900, and the borrower's checking account balance (a liability for the bank) also increases by 900. This deposit of newly created money can then be spent and redeposited in another bank, initiating a new round of lending.
Fractional Reserve System: Modern banking operates under a fractional reserve system, where banks keep only a fraction of their deposits as reserves and lend out the rest.
This system allows banks to create money through lending, as the loaned funds, when redeposited, become new demand deposits.
Banks operate this way to maximize profits by earning interest on loans, while maintaining enough liquidity to meet typical withdrawal demands, relying on the public's trust that deposits are safe.
Multiple Expansion of Deposits: A single initial deposit into the banking system can lead to a much larger overall increase in the money supply through a process known as the multiple expansion of deposits. This effect is quantified by the money multiplier.
The simple money multiplier is calculated as 1 / Required : Reserve : Ratio. For instance, with a 10 \% reserve ratio, a 1,000 deposit could theoretically lead to a 10,000 increase in the money supply.(\frac{1}{0.10} \times \$1,000 = \$10,000)
This process assumes that all loaned money is redeposited and that banks lend out all excess reserves. In reality, factors like currency drain (people holding cash instead of depositing) and banks holding excess reserves limit the actual money multiplier effect.
14.4 The Federal Reserve System
Role of the Fed: The Federal Reserve (the Fed) is the central bank of the United States, established in 1914 largely in response to the frequent bank panics that plagued the country in the late 19th and early 20th centuries.
Its primary roles include managing monetary policy, supervising and regulating banks, and acting as a lender of last resort to commercial banks experiencing liquidity problems. This function is crucial for preventing widespread bank runs and maintaining financial stability, as dramatically illustrated during the Great Depression.
Structure: The Fed's structure is designed to be decentralized yet coordinated.
Board of Governors: Seven members appointed by the President and confirmed by the Senate, serving 14-year terms. They set monetary policy and oversee the 12 Federal Reserve Banks.
Federal Open Market Committee (FOMC): The main policymaking body, consisting of the seven governors and five rotating presidents of the Federal Reserve Banks (with the New York Fed president always having a vote). The FOMC manages open market operations—buying and selling government securities to control the money supply and influence interest rates.
The Fed also sets discount rates, which are the interest rates at which commercial banks can borrow funds directly from the Fed. Adjusting this rate is another tool to influence bank reserves and lending.
Historical Context and Modern Applications
FDIC's Role Post-Great Depression: The Federal Deposit Insurance Corporation (FDIC) was established in 1934 in the wake of the Great Depression to restore public confidence in the banking system.
It insures deposits up to a specified limit (250,000 per depositor, per bank, per ownership category). By providing this insurance, the FDIC significantly reduces the incentive for bank runs, ensuring that even if a bank fails, depositors will not lose their insured savings.
Shadow Banking System: This term describes a collection of non-bank financial intermediaries that provide credit and engage in traditional banking activities but operate outside the traditional regulatory oversight of the central bank and deposit insurance systems.
Examples include investment banks, money market mutual funds, and hedge funds. While they enhance financial innovation and efficiency, their lack of stringent regulation and interconnectedness can pose significant systemic risks, as they are not subject to the same capital requirements or liquidity rules as commercial banks.
2007-2009 Financial Crisis: This severe economic downturn was significantly triggered by widespread failures within the shadow banking system and excessive reliance on highly leveraged, complex financial instruments.
Key factors included the proliferation of subprime mortgages, securitization of these risky loans (creating Mortgage-Backed Securities or MBS), and a lack of transparency and regulation, leading to a breakdown in trust and liquidity across financial markets.
14.5 The Quantity Theory of Money
Conceptual Framework: The Quantity Theory of Money (QTM) is a classical economic theory that posits a direct relationship between the quantity of money in an economy and the price level of goods and services. It is a fundamental concept in macroeconomics for understanding inflation.
The theory suggests that if the amount of money in an economy doubles, price levels will also double, assuming the velocity of money and real output remain stable in the short run. This implies that inflation is primarily a monetary phenomenon.
Irving Fisher's Equation: The QTM is often expressed through the Equation of Exchange, formulated by Irving Fisher:
M \times V = P \times Y
M (Money Supply): The total amount of money circulating in the economy (e.g., M1 or M2).
V (Velocity of Money): The average number of times a unit of money is spent on new goods and services in a specific period. It reflects how quickly money circulates through the economy.
P (Price Level): The average price of all goods and services in the economy (e.g., measured by the Consumer Price Index or GDP deflator).
Y (Real Output/Real GDP): The total quantity of goods and services produced in the economy, adjusted for inflation. This represents the real value of transactions.
The equation is an accounting identity; it must always hold true. However, the QTM asserts a causal link, particularly that changes in M lead to proportional changes in P, especially when V and Y are stable or change slowly.
Interpreting Inflation Rates: The quantity equation can be expressed in terms of growth rates to analyze inflation:
\% \Delta M + \% \Delta V = \% \Delta P + \% \Delta Y
This shows that the growth rate of the money supply plus the growth rate of velocity approximately equals the growth rate of the price level (inflation) plus the growth rate of real output.
Therefore, if velocity and real output growth are relatively stable, inflation is largely determined by the growth rate of the money supply.\pi \approx \% \Delta M - \% \Delta Ywhere $\pi$ is the inflation rate.
Hyperinflation examples (e.g., Weimar Republic, Zimbabwe, Venezuela) vividly illustrate extreme monetary expansion without corresponding economic growth. In these cases, governments print vast amounts of money to finance expenditures, leading to a dramatic and rapid erosion of the currency's value, rendering money effectively useless as a store of value and, eventually, as a medium of exchange.
Conclusion
The notes comprehensively cover critical aspects of banking, the pivotal role of the Federal Reserve in monetary policy, the measurement and creation of money, and historical implications of financial crises. A deep understanding of these macroeconomic components highlights the paramount importance of stability, confidence, and sound regulation within monetary and financial systems for sustained economic growth and prosperity.
