Expansionary Fiscal Policy
Tax cuts, spending boosts — and the currency consequences
- Define expansionary fiscal policy and its main tools
- Predict short-term vs long-term currency effects
- Spot when expansion will spook the bond market
A tax cut should boost the currency, right? More growth, more demand, more confidence. Often it does — for about a week. Then the bond market wakes up to the deficit, yields rise on FEAR not growth, and the currency tanks. Timing matters.
What expansion looks like
Expansionary fiscal = the government deliberately runs a bigger deficit. Tools: cut taxes (income, corporate, VAT), boost spending (infrastructure, transfers, defence), or both. The goal is to lift demand. The cost is more debt.
Headline = stimulus. Equities rally, growth forecasts get upgraded. Currency often initially STRENGTHENS on growth optimism.
Bond market re-prices the deficit. Yields rise from sovereign-risk premium, not growth. Currency weakens as fiscal indiscipline is priced. Truss 2022 textbook.
When it works vs when it backfires
Expansion into a recessionary gap (slack economy) usually works — boosts demand, doesn't spike inflation. Expansion into a positive output gap (already hot) backfires — adds inflation pressure, forces the CB to hike harder, currency suffers from policy mix tension.
Expansionary fiscal announced when economy is at full employment + CPI 5%. Likely medium-term currency direction?
- Expansion = bigger deficit via tax cuts or spending boost
- Short-term: often currency-positive on growth optimism
- Medium-term: deficit + inflation concerns can punish currency
- Works in recession; backfires in expansion
