What fiscal policy is
Fiscal policy is how a government spends and taxes. It is set by the government and parliament through the budget. Monetary policy is set separately by the central bank through interest rates and liquidity.
The two work together. A central bank sets the short-term rate. Fiscal decisions shape how much the government borrows, which affects longer-term yields, inflation and confidence in the currency.
For the monetary side, see Interest rates and Central banks and currencies.

Deficit, debt and how they are financed
- Fiscal deficit: spending is higher than revenue in a budget year.
- Primary deficit: the deficit before interest payments on existing debt.
- Government debt: the total stock of past borrowing that is still outstanding.
- Debt service: interest and principal the government must pay.
A government can cover a deficit in several ways:
- Domestic bond and bill auctions. It sells debt to local banks and investors.
- External borrowing. It sells bonds abroad or borrows from foreign lenders in foreign currency.
- Central bank financing. The central bank lends to the government directly, or buys its debt. Markets usually treat this as an inflation risk.
The financing method often matters more to markets than the deficit itself.
Bond supply and yields
A larger deficit usually means more government bonds offered at auctions. If demand does not rise at the same pace, buyers ask for a higher yield. The yield is the return a buyer gets for holding the bond at the current price.
Markets also add a term premium, which is extra yield for holding long-dated debt when the fiscal path is uncertain. That is why fiscal news often moves the long end of the yield curve more than the short end. See Yield curve and Bond yields and FX.
Central bank balance-sheet policy matters too. When a central bank shrinks its bond holdings, private buyers must absorb more supply. See QE and QT.
How fiscal policy reaches the currency
No single fixed rule applies. Several channels act at the same time, and they can pull in opposite directions:
| Channel | What happens | Typical currency effect |
|---|---|---|
| Higher yields from more borrowing | Foreign buyers are paid more to hold the currency | Can support it |
| Stronger demand from stimulus | Growth and inflation expectations rise, so the central bank may stay tight | Can support it |
| Credibility concern | Investors doubt the debt path and ask for a risk premium | Can weaken it |
| Central bank financing | Money supply and inflation expectations rise | Usually weakens it |
| External debt in foreign currency | Repayment needs foreign exchange, which pressures reserves | Can weaken it |
| Wider current account deficit | Imports rise faster than exports | Can weaken it |
In large, liquid markets, higher yields often support the currency at first. Where debt is high, reserves are thin or inflation is a concern, the credibility channel can dominate. Then yields rise while the currency falls. This pattern is a warning sign of fiscal stress.

Fiscal and monetary policy together
When a budget adds to demand or to inflation pressure, the central bank may respond with tighter policy. In Pakistan, the State Bank of Pakistan (SBP) sets the policy rate through its Monetary Policy Committee. Its latest announced decision reads: SBP policy rate raised by 50 bps to 12% with effect from 27.10.2026 (MPC).
Monetary policy statements often discuss the fiscal stance. For that reason, budget numbers and rate decisions are best read side by side. See SBP rates and economy and Real interest rates.
Budget days and the market calendar
Fiscal events follow published schedules. Take dates from official sources only: the finance ministry, the debt office, the central bank and the rating agencies. Events to watch:
- Budget presentation to parliament, followed by debate and approval.
- Mid-year reviews and revised estimates.
- Bond and bill auction calendars, which list planned sizes and maturities.
- Monthly fiscal operations data, meaning revenue, spending and deficit reports.
- Sovereign rating reviews and outlook changes.
- Lender programme reviews, where they apply.
Markets usually price a budget before it is presented. The reaction depends on the gap between what was announced and what was expected. Watch for:
- the deficit target compared with expectations,
- whether the revenue measures look realistic,
- the planned borrowing mix between domestic and external debt,
- auction results: demand compared with the amount offered, and the yield accepted.
See Economic calendar guide and Economic surprises. Election periods often bring fiscal promises, which are covered in Elections and markets.
Where to get the figures
Use only official releases for deficit, debt and yield figures: the finance ministry's fiscal reports, central bank statistics and debt office auction results. Third-party summaries can be late or rounded. Always note the release date and whether a figure is provisional or revised.
For the Pakistani rupee, also note the exchange rate regime and any capital controls. Both shape how fiscal news shows up in the exchange rate. See Exchange rate regimes and Capital controls.
Risk
Fiscal events can cause sharp moves in yields and currencies, and spreads can widen around announcements. If you trade leveraged forex or CFDs, losses can exceed what you expect and can happen fast. This guide explains mechanisms only. It is not a signal or a forecast. Read Risk management before trading any event.
Frequent questions
Does a bigger fiscal deficit always weaken a currency?
No. Higher yields can support a currency, while credibility concerns or central bank financing can weaken it. The outcome depends on how the deficit is financed and how much investors trust the debt path.
Why do long-term bond yields react more than short-term ones?
Short-term rates track the central bank. Long-term yields carry a term premium that reflects uncertainty about future borrowing.
What should I compare on budget day?
Compare the announced deficit and borrowing plan with what markets expected. Then follow auction results and rating agency comments.
Where do I find budget and auction dates?
Use the finance ministry, the debt office and central bank calendars. The Economic calendar guide explains how to read event listings.
Is fiscal policy the same as monetary policy?
No. The government sets fiscal policy through taxes and spending. The central bank sets monetary policy through interest rates and liquidity.
