When the economy stalls, two different hands can reach for the controls. One holds the government's budget. The other holds the interest rate. Mixing them up is the classic mistake of this week.
Learning objectives. After this week you can (1) tell fiscal from monetary policy; (2) say when each is expansionary or contractionary; and (3) work out how a rate change reaches an investment like a new lift.
Remember this: fiscal policy is government spending and taxes. Monetary policy is the central bank's interest rates and money supply.
1) Two levers on the economy
- Fiscal policy is run by the government. Cutting taxes or raising spending is expansionary; raising taxes or cutting spending is contractionary.
- Monetary policy is run by the central bank, mainly through its policy interest rate. Lowering rates or growing the money supply is expansionary; raising rates ("tightening") is contractionary.
The central bank does not set tax rates, and the legislature does not set the policy rate.
2) Matching policy to the cycle
| Problem | Policy it calls for | Examples |
|---|---|---|
| Recession | Expansionary | Cut rates, cut taxes, raise spending |
| High inflation | Contractionary | Raise rates, raise taxes, cut spending |
Both kinds work mostly by moving aggregate demand: higher taxes pull it down, lower rates push it up.
3) How a rate change reaches a new lift
Annual Interest on an Investment = Amount Borrowed × Rate
A $50,000 lift financed at 6% costs 50,000 × 0.06 = $3,000 a year. If a tightening adds four points, the same lift at 10% costs $5,000: $2,000 a year more for the identical lift. That is how monetary policy reaches real investment. When rates are low, investment is cheaper to finance; when hikes are expected, borrowers who need money may borrow sooner, and when cuts are expected, waiting can pay.
4) Policy and your resort
Your Daily Report does not print a central bank rate. Your loan's rate comes from your own credit rating, and in Week 4 you learned to read it off your report (daily interest × 365 ÷ balance). This week's question is the policymaker's one: what would a higher rate do to a decision your crew is weighing, such as a loan draw or CapEx?
Quick self-check
(a) To fight high inflation, does the central bank raise or lower rates? (b) Is a tax cut fiscal or monetary, expansionary or contractionary? (c) $40,000 borrowed at 5%, then at 8%. Extra interest per year? (Answers: raise; expansionary fiscal; 40,000 × 0.03 = $1,200.)
Common mistakes
- Mixing up the two levers. Taxes and spending are fiscal; rates are monetary.
- Calling a rate hike expansionary. Raising rates slows the economy.
- Pricing an investment without its financing. The interest is part of what it costs.
This week in the arena
Take one investment your crew has talked about, a loan draw or a CapEx amount. Work out its annual interest at the rate your report implies, then again at four points higher. Would the bigger number change your crew's answer?
