6.6 Monetary policies

Monetary policy in the United States has evolved from colonial experiments to a complex system managed by the Federal Reserve. This journey reflects changing economic theories, national priorities, and global financial dynamics.

The Federal Reserve, established in 1913, now uses various tools to balance price stability and employment. Its policies have adapted to major events like the Great Depression, the end of the gold standard, and recent financial crises.

Origins of US monetary policy

Before there was a central bank, the American colonies and early republic wrestled with a basic question: who controls the money supply, and how? The answers they came up with laid the groundwork for everything that followed.

Colonial monetary experiments

Individual colonies issued their own paper currency to address chronic coin shortages. Massachusetts Bay Colony led the way in 1690, printing the first paper money in British North America to pay soldiers returning from an expedition against Quebec.

The problem was predictable: with no coordination between colonies and no standard backing, overprinting led to depreciation and inflation. British Parliament responded with the Currency Act of 1751, which restricted colonial paper money. This created real economic tensions that fed into broader colonial grievances.

First and Second Banks

• First Bank of the United States (1791–1811): Alexander Hamilton pushed for this institution to stabilize the new nation's currency and facilitate tax collection. It worked reasonably well, but states' rights advocates saw it as federal overreach. Congress declined to renew its charter.
• Second Bank of the United States (1816–1836): Created to clean up the financial mess left by the War of 1812, it regulated state banks and stabilized currency. Andrew Jackson viewed it as a corrupt tool of eastern elites and vetoed its recharter, ushering in the Free Banking Era.

Free Banking Era

From 1837 to 1863, the U.S. had a decentralized banking system where state-chartered banks issued their own currency backed by various assets. The results were chaotic: no uniform currency, rampant counterfeiting, and "wildcat banks" that took excessive risks (some literally set up shop in remote areas to make it hard for customers to redeem notes).

The National Banking Acts of 1863 and 1864 ended this era by establishing a national currency and a system of nationally chartered banks.

Federal Reserve System

The creation of the Fed in 1913 was the most important structural change in American monetary history. It addressed the recurring financial panics that had plagued the economy for decades.

Creation and structure

The Federal Reserve Act of 1913 came directly out of the Panic of 1907, which had required J.P. Morgan to personally organize a private bailout of the banking system. Congress decided the country needed an institutional solution.

The structure was deliberately decentralized to ease fears of concentrated financial power:

• 12 regional Federal Reserve Banks spread across the country
• A Federal Reserve Board (now the Board of Governors) in Washington, D.C.
• Member banks required to hold reserves with the Fed
• A dual mandate to promote maximum employment and stable prices

Objectives and tools

The Fed's two core objectives are price stability (typically targeting around 2% inflation) and full employment. To achieve these, it relies on three main tools:

• Open market operations: Buying and selling government securities to influence the money supply
• Federal funds rate: Setting the target rate at which banks lend to each other overnight, which ripples through the entire economy's borrowing costs
• Reserve requirements: Dictating how much cash banks must keep on hand (though this tool has become less central in recent years)

Independence vs. accountability

The Fed operates independently within the government, meaning elected officials can't directly order it to raise or lower rates. This insulation from short-term political pressure is considered essential for credible monetary policy.

That said, it's not unaccountable. The Board of Governors is appointed by the President and confirmed by the Senate. The Fed Chair testifies before Congress regularly, and the Fed publishes detailed reports on its decisions and economic outlook.

Major monetary policy eras

Each era of U.S. monetary policy reflects the dominant economic thinking of its time and the specific crises that forced change.

Gold Standard period

The U.S. officially adopted the gold standard in 1879, meaning the dollar was convertible to a fixed amount of gold. This system provided price stability and fixed exchange rates between countries, but it came with a serious drawback: the money supply could only grow as fast as gold reserves. During economic downturns, the government couldn't expand the money supply to stimulate recovery, which led to periodic bouts of painful deflation.

Great Depression policies

The Depression exposed the gold standard's rigidity. Key policy shifts included:

• 1933: President Roosevelt took the U.S. off the gold standard domestically, freeing the Fed to expand the money supply
• Banking Act of 1933 (Glass-Steagall): Separated commercial banking from investment banking to reduce speculation
• FDIC creation: Deposit insurance restored public confidence in banks and stopped bank runs
• Expanded Fed powers: The Federal Reserve gained broader authority to conduct open market operations

Bretton Woods system

Established at a 1944 conference in New Hampshire, this system created a new international monetary order. The U.S. dollar was pegged to gold at $\$35$ per ounce, and other countries pegged their currencies to the dollar. This gave countries more flexibility in domestic monetary policy while maintaining stable exchange rates.

The system worked for about 25 years but collapsed in 1971. Persistent U.S. trade deficits and declining gold reserves made the fixed peg unsustainable.

Post-1971 fiat money

When President Nixon ended dollar-to-gold convertibility (the "Nixon Shock"), the world shifted to floating exchange rates and fiat money, meaning currency backed by government authority rather than a physical commodity.

This gave central banks far more flexibility but also more responsibility. The decades that followed saw the development of inflation targeting frameworks (formalized in the 1990s) and a growing emphasis on transparency and forward guidance as tools in their own right.

Key monetary policy tools

Open market operations

This is the Fed's primary tool. The process works like this:

1. The Federal Open Market Committee (FOMC) decides on a target for the federal funds rate
2. The New York Fed's trading desk buys or sells U.S. government securities on the open market
3. Buying securities puts money into the banking system, increasing the money supply (expansionary)
4. Selling securities pulls money out, decreasing the money supply (contractionary)
5. These transactions shift the supply of bank reserves, pushing the federal funds rate toward the FOMC's target

Discount rate

The discount rate is the interest rate the Fed charges banks for short-term loans directly from the Fed. It serves two functions:

• Signal: Changes in the discount rate communicate the Fed's policy stance to markets
• Lender of last resort: During crises, banks that can't borrow elsewhere can turn to the Fed's "discount window"

A higher discount rate discourages borrowing and slows economic activity. A lower rate does the opposite.

Reserve requirements

Reserve requirements set the minimum percentage of deposits that banks must hold in reserve rather than lend out. Higher requirements reduce banks' lending capacity; lower requirements expand it.

In March 2020, the Fed set reserve requirements to zero in response to the COVID-19 pandemic. Since then, the Fed has relied more heavily on other tools, particularly interest on excess reserves (IOER), to influence how much banks lend.

Inflation targeting

Evolution of inflation goals

Through the 1970s and 1980s, the Fed focused on controlling the money supply directly. By the 1990s, the approach shifted toward explicit inflation targets, which proved more effective at anchoring expectations.

The Fed formally adopted a 2% inflation target in 2012. In 2020, it moved to average inflation targeting, meaning it would tolerate inflation running above 2% for a period if it had previously been running below. The goal was to prevent the kind of persistent undershooting that had characterized the post-2008 recovery.

Price stability vs. employment

The Fed's dual mandate creates inherent tension. The Phillips Curve describes a short-term trade-off: pushing unemployment lower tends to push inflation higher, and vice versa. In the long run, the Fed tries to anchor inflation expectations so that both goals can be pursued without one constantly undermining the other.

Defining "full employment" is itself a challenge, since the labor market's structure changes over time due to demographics, technology, and other factors.

Forward guidance strategies

Forward guidance means the Fed communicates its future policy intentions to shape market expectations today. There are two main approaches:

• Time-based guidance: "We expect to keep rates near zero through at least 2023"
• State-contingent guidance: "We won't raise rates until unemployment falls below X% and inflation reaches Y%"

By telling markets what to expect, the Fed can influence long-term interest rates and investment decisions even before it actually changes policy.

Unconventional monetary policies

When the federal funds rate hits zero, the Fed can't cut rates any further. That's when unconventional tools come into play.

Quantitative easing

Quantitative easing (QE) involves the Fed purchasing large quantities of government bonds and other securities to inject liquidity into financial markets. This expands the Fed's balance sheet and pushes down long-term interest rates, encouraging borrowing and investment.

The Fed deployed QE on a massive scale after the 2008 financial crisis (three rounds between 2008 and 2014) and again during the COVID-19 pandemic in 2020. Critics point to potential side effects: inflated asset prices, growing wealth inequality, and the risk of future inflation when all that liquidity eventually works through the system.

Negative interest rates

Some central banks (the European Central Bank, Bank of Japan, and others) have experimented with charging banks interest on excess reserves held at the central bank. The idea is to penalize banks for sitting on cash rather than lending it out.

The Fed has not adopted negative rates, and there's significant debate about whether they actually work. Concerns include squeezing bank profitability and potentially destabilizing the financial system.

Yield curve control

Under yield curve control (YCC), a central bank targets specific long-term interest rates by committing to buy whatever quantity of bonds is necessary to hold rates at that level. The Bank of Japan has used this approach since 2016.

YCC differs from QE in that the central bank commits to a rate target rather than a purchase amount. This can potentially achieve similar effects with fewer purchases, but it risks the central bank losing control over the size of its balance sheet if markets test its commitment.

Monetary policy during crises

Crises force the Fed to innovate, and those innovations often become permanent additions to the policy toolkit.

Great Depression responses

The Fed's biggest failure during the Depression was its inaction. It failed to serve as lender of last resort, allowing thousands of banks to fail and the money supply to contract by roughly a third between 1929 and 1933. The lessons learned reshaped the institution:

• Abandoning the gold standard allowed monetary expansion
• Deposit insurance (FDIC) stopped bank runs
• Expanded Fed powers created the framework for modern monetary policy

1970s stagflation management

Stagflation (simultaneous high inflation and high unemployment) broke the existing Keynesian models that assumed you couldn't have both at once. Inflation reached double digits by the late 1970s.

Fed Chair Paul Volcker's response was dramatic: he raised the federal funds rate to nearly 20% by 1981. This deliberately triggered a severe recession but succeeded in breaking inflation. The episode established the principle that central bank credibility in fighting inflation is worth short-term economic pain, and it strengthened the case for Fed independence.

2008 financial crisis interventions

The Fed's response to the 2008 crisis was unprecedented in speed and scope:

1. Rapidly cut the federal funds rate from 5.25% to near zero
2. Launched quantitative easing, eventually purchasing trillions in securities
3. Created emergency lending facilities for specific markets (commercial paper, money market funds)
4. Established currency swap lines with foreign central banks to prevent global dollar shortages
5. Expanded forward guidance to manage market expectations about future rate paths

COVID-19 pandemic measures

The pandemic response built on the 2008 playbook but went further:

1. Cut rates to zero within weeks of the crisis emerging
2. Relaunched and expanded QE programs
3. Created new lending facilities to support businesses and even municipal governments
4. Provided forward guidance indicating rates would stay low for an extended period
5. Adopted average inflation targeting, signaling tolerance for temporary inflation overshooting

International monetary coordination

The U.S. dollar's role as the world's primary reserve currency means Fed decisions ripple across the globe, making international coordination both necessary and complicated.

Exchange rate policies

After Bretton Woods collapsed, most major economies shifted to floating exchange rates, though many countries manage their floats to varying degrees. Key developments include:

• Plaza Accord (1985): Major economies coordinated to weaken the dollar, which had become overvalued
• Louvre Accord (1987): A follow-up agreement to stabilize exchange rates after the Plaza Accord's success
• Ongoing debates over currency manipulation, particularly regarding countries that intervene to keep their currencies artificially weak to boost exports

Currency swap agreements

These bilateral agreements allow central banks to exchange currencies, providing liquidity in foreign currencies during market stress. The Fed dramatically expanded its swap lines during both the 2008 crisis and the COVID-19 pandemic to prevent dollar shortages abroad from destabilizing global markets.

Global financial stability efforts

Several international institutions coordinate monetary and financial policy:

• Bank for International Settlements (BIS): Facilitates cooperation among central banks
• Basel Accords: Set international standards for bank capital requirements and regulation
• Financial Stability Board: Coordinates national financial authorities and standard-setting bodies
• IMF: Provides policy advice and emergency financial assistance to member countries
• G7/G20 summits: Address global economic challenges through high-level policy coordination

Critiques and debates

Austrian School vs. Keynesian

These two schools of thought represent fundamentally different views of what central banks should do:

Most modern central banking falls closer to the Keynesian camp, but Austrian critiques gained renewed attention after the 2008 crisis, when critics argued that the Fed's low-rate policies in the early 2000s had helped inflate the housing bubble.

Rules vs. discretion

• Rules-based approach: The Fed should follow predetermined formulas. The most famous is the Taylor Rule, which calculates where interest rates should be based on the gap between actual and target inflation and the gap between actual and potential GDP. Advocates argue this reduces policy errors and increases predictability.
• Discretionary approach: The economy is too complex for any single rule to capture. Policymakers need flexibility to respond to unforeseen circumstances. Critics counter that discretion opens the door to inconsistency and political influence.

Monetary policy limitations

Even supporters of active monetary policy acknowledge real constraints:

• The zero lower bound limits how far conventional rate cuts can go
• Unconventional tools like QE may face diminishing returns with repeated use
• Key economic variables (the output gap, the natural rate of interest) are difficult to measure in real time
• Prolonged easy money can produce unintended consequences: asset bubbles, increased wealth inequality, and excessive risk-taking in financial markets

Future of US monetary policy

Digital currencies impact

Central Bank Digital Currencies (CBDCs) are under active study at the Federal Reserve. A digital dollar could enhance payment systems and give the Fed new channels for monetary policy transmission, but it raises thorny questions about privacy, cybersecurity, and the potential to displace traditional bank deposits.

Meanwhile, private cryptocurrencies and stablecoins are forcing the conversation. If widely adopted, they could complicate the Fed's ability to control the money supply and monitor financial flows.

Climate change considerations

Central banks are increasingly grappling with climate-related financial risks. Proposals include "green" QE (tilting asset purchases toward climate-friendly investments) and adjusting collateral frameworks to account for climate risk. The challenge is balancing these objectives with the Fed's existing mandate without overstepping into fiscal policy territory.

Potential structural reforms

Several reform proposals are actively debated:

• Expanding the mandate: Adding explicit financial stability or inequality targets
• Alternative frameworks: Nominal GDP targeting or price level targeting instead of inflation targeting
• Governance reforms: Improving diversity and regional representation within the Federal Reserve System
• Accountability adjustments: Enhancing democratic oversight while preserving the operational independence that makes credible monetary policy possible
