CONCEPTWho 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 RULE2 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 ITEach lever has its limit
“Inflation is always and everywhere a monetary phenomenon.”
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.
EXAMPLE
IN A CRISISWhen the two levers kick in
Illustrative figures. Monetary tends to react fast; fiscal is slower but hits the wallet more directly.
An illustrative curve of the economy in a crisis. When it bottoms, government and central bank usually act together to restart it.
- 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 MONETARYThe 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 WHATHow the economic policy levers split up
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 ETFsFive 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.
