CONCEPT

Who really runs the economy?

It isn't one hand. It's two separate levers, in separate hands, that sometimes push together and sometimes get in each other's way.

LEVER 1

FISCAL

government: spending and taxes

LEVER 2

MONETARY

central bank: rates

GOAL

stabilize

growth and prices

THE IDEA

2

→ two levers to move the economy

Fiscal policy is run by the government through public spending and taxes. Monetary policy is run by the central bank through interest rates and the money supply. Knowing which one is in use explains almost any economic headline.

THE IDEA

SIMPLE RULE

2 levers

2

one from the government, one from the central bank

Think of a car: the government decides how much fuel to add; the central bank, how hard to press the accelerator.

One is pulled by a politician with a budget; the other by a central banker with an interest rate. Almost everything economic runs through one of the two.

BUDGET
A government's annual plan of income and spending.
INTEREST RATE
The price of money: what it costs to borrow or earns to save.

QUOTE

TO GRASP IT

Each lever has its limit

Inflation is always and everywhere a monetary phenomenon.
Milton Friedman · Economist · Nobel laureate

Economists have argued for a century over which one works best. The honest answer: it depends on the problem.

INFLATION
A broad, sustained rise in prices.
NOBEL
The benchmark prize in economics and other fields.

Illustrative figures. Monetary tends to react fast; fiscal is slower but hits the wallet more directly.

RECESSION
A phase where the economy contracts for several months.
TRANSMISSION
The time a measure takes to show up in the real economy.

HEAD TO HEAD

FISCAL vs MONETARY

The two levers, side by side

FISCAL POLICY

Run by the government

  • Tools: public spending and taxes.
  • Straight to the wallet: benefits, public works, tax cuts.
  • Slower: it needs political approval and time.

MONETARY POLICY

Run by the central bank

  • Tools: interest rates and the money supply.
  • Indirect: it moves credit, stocks and mortgages.
  • Faster: decided in one meeting, acts within days.

Same goal, different tools. Here's how they differ in who decides, what they touch, and how fast.

PUBLIC SPENDING
What the state invests in works, services and benefits.
CREDIT
Borrowed money that drives consumption and investment.

THE TOOLS

WHO TOUCHES WHAT

How the economic policy levers split up

INTEREST RATES: 30%PUBLIC SPENDING: 30%BOND BUYING: 20%TAXES: 20%LEVERS50/50
INTEREST RATESCentral bank · the price of money30%
PUBLIC SPENDINGGovernment · investment and benefits30%
BOND BUYINGCentral bank · injects liquidity20%
TAXESGovernment · slows or spurs spending20%

Blue is the central bank; green is the government. When they push the same way, the effect multiplies.

Roughly speaking, each side controls half the board. Neither can do it all alone.

BOND BUYING
The central bank buys debt to inject money into the system.
LIQUIDITY
Money available circulating in the economy.

WATCHLIST

5 TEACHING ETFs

Five assets that react to each lever

TLT~90 +0.0%Long bonds. They rise when monetary policy cuts rates.
XLI~140 +0.0%Industrials. They benefit from public infrastructure spending (fiscal).
GLD~415 +0.0%Gold. A shelter when money is printed or spending runs unchecked.
UUP~27 +0.0%Dollar. It strengthens under tight monetary policy, weakens under loose.
SHY~82 +0.0%Short bonds. They track directly the rate the central bank sets.

Representative examples to see the concept. Approximate prices, not today's.

ETF
A listed basket that tracks an index or asset.
INFRASTRUCTURE
Public works: roads, grids, energy. A classic channel for fiscal spending.
