Learn about currency, trade, and fiscal deficit

Overview

Understanding currency dynamics, trade balances, and fiscal deficits is critical for stock investors because these macroeconomic factors directly impact corporate earnings, interest rates, and market valuations. A weakening currency can boost exporters but hurt importers; persistent deficits signal government borrowing that crowds out private investment and raises interest rates.

Currency Fundamentals

$\text{Real Exchange Rate} = \text{Nominal Rate} \times \frac{\text{Foreign Price Level}}{\text{Domestic Price Level}}$

WHY this formula? Because if India has10% inflation and US has 2%,₹1 buys 10% less domestically. To compare purchasing power across borders, we must adjust for these inflation differences.

Currency Appreciation vs Depreciation

Depreciation: Currency becomes less valuable (more units needed)

• USD/INR rises from ₹83 to ₹86 → Rupee depreciated
• Impact: Exports competitive, imports expensive, imported inflation rises

HOW does this affect stocks?

1. IT/Pharma exporters (Infosys, Dr. Reddy's): ~70% revenue in USD → rupee depreciation = windfall
2. Airlines/Oil refiners (IndiGo, BPCL): Import fuel in USD → rupee depreciation = margin squeeze
3. Auto/Consumer (Maruti, Nestle): Import raw materials → mixed impact

Assume Infosys earns $100M in a quarter.

• Scenario A: USD/INR = ₹82→ Revenue = ₹8,200M
• Scenario B: USD/INR = ₹85 → Revenue = ₹8,500M

Same dollar revenue, but ₹300M more in rupee terms (3.6% revenue boost) just from currency!

Why this step? Infosys reports in rupees but earns in dollars. A 3% currency move translates directly to 3% topline change, boosting EPS if costs are rupee-denominated (salaries, rent).

Real data: In Q2 FY24, Infosys reported ₹38,994 crore revenue. ~1% came from currency tailwinds per management commentary.

Trade Deficit

$\text{Trade Balance} = \text{Exports} - \text{Imports}$

Negative = Deficit; Positive = Surplus

WHY does this matter? A trade deficit means net outflow of domestic currency → downward pressure on currency → affects inflation and interest rates.

Components of Current Account

HOW it works — step by step:

1. India imports $100B oil → Dollars flow out, rupees flow in (to foreign sellers)
2. India exports $80B services → Dollars flow in, rupees flow out (to Indian firms)
3. Net: $20B deficit → More dollars demanded than supplied → Rupee weakens

• Merchandise Trade: -$267B (exports$447B, imports $714B)
• Services Trade: +$147B (exports$322B, imports $175 IT services dominate)
• Remittances: +$111B (NRIs sending money home)
• Net Current Account: -$67B (~2% of GDP)

Why each step?

• Oil/gold imports are inelastic → persistent deficit source
• IT services surplus partially offsets → rupee support
• Remittances act as cushion → forex reserves stable

What happened? Despite large goods deficit, India avoided currency crisis because services + remittances balanced ~70% of the gap. RBI intervened with $100B forex reserves sale to smooth rupee volatility.

Twin Deficits Problem

The mechanism:

1. Government runs fiscal deficit → Issues bonds → Competes with private sector for savings
2. Trade deficit → Need foreign capital inflows to finance
3. To attract foreign capital → Must offer higher interest rates → Corporate borrowing costs rise → Earnings compress

Why it feels right: Intuitively, spending more than earning sounds like disaster.

The fix: Trade deficits aren't inherently bad if:

1. Imports are capital goods (machinery, tech) that boost future productivity → India1990s imported computers, built IT sector
2. Financed by FDI/equity, not debt → USA runs persistent deficits but attracts investment
3. Temporary due to commodity price spike (oil shock) → India 2022 oil spike

Red flag: Persistent deficit financed by debt (hot money) → Vulnerable to sudden stops (1997 Asia crisis, 2013 India "Taper Tantrum").

Fiscal Deficit

$\text{Fiscal Deficit} = \text{Total Expenditure} - \text{Total Revenue (Tax + Non-Tax)}$

Expressed as % of GDP. India's FRBM Act target: <3% (rarely met).

WHAT does government do with deficit? Issues bonds → Borows from market.

1. Government issues₹10 lakh crore bonds to fund deficit
2. Banks buy these bonds (risk-free, attractive) → Less capital for private loans
3. Corporate borrowing rates rise → Capex delayed → GDP growth slows

$\text{Interest Rate}_{\text{corporate}} \uparrow \implies \text{Cost of Capital} \uparrow \implies \text{NPV of Projects} \downarrow$

WHY this matters for stocks:

• BFSI sector (SBI, HDFC Bank): Huge government bond holdings → Interest rate risk
• Infra/Capex (L&T, Adani): Higher borrowing costs → Project IRs squezed
• Defensives (HUL, ITC): Less affected, stable cash flows

• Total Revenue: ₹30.8 lakh crore (Tax: ₹26.0 LC, Non-tax: ₹4.8 LC)
• Total Expenditure: ₹47.7 lakh crore (Subsidies: ₹4.1 LC, Interest: ₹11.6 LC, Capex: ₹11.1 LC)
• Fiscal Deficit: ₹16.9 lakh crore (5.1% of GDP, target was 5.9%)

Step-by-step impact:

1. ₹16.9 LC borrowing → Government bond supply floods market
2. 10-year yield rises from 7.0% → 7.3% (Jan-Mar 2024actual movement)
3. Corporate bond yields follow → AA spreads widen to 7.8%
4. L&T's metro project: Earlier IR 14%, borrowing at 7.5% → Net 6.5%; Now borrowing at 7.8% → Net 6.2% → Marginal projects shelved

Why this step? Government competes for the same savings pool as corporates. When government sucks up ₹17 LC, corporate access to capital shrinks → Equity markets reprice for lower growth.

Fiscal Deficit Funding Sources

WHY differentiate?

• Market borrowings: Crowds out private sector ❌
• Small savings: Locks household savings, reduces equity investment ⚠️
• External debt: Currency risk if rupee depreciates 🔴

HOW to assess investor:

• Fiscal Deficit: 12% of GDP (unsustainable)
• Funded 40% via foreign borrowing → $51B external debt
• Currency collapsed: LKR depreciated 80% in 6 months
• Stock market: Colombo index down 43% (FY22)

What went wrong — step by step:

1. Borrowed in USD, earned in LKR → Currency mismatch
2. Tourism collapsed (COVID) → Forex inflows dried up
3. Couldn't repay debt → Default IMF bailout → Austerity → Recession

Lesson for investors: Check government debt-to-GDP (India 84%, manageable; SL was 110%) and external debt component (India 20% of total, safe; SL 50%, dangerous).

Interconnections: The Macroeconomic Triangle

1. Fiscal deficit → Government borows → Interest rates rise
2. High interest rates → Currency appreciates (foreign capital inflows) → BUT
3. Trade deficit → Currency depreciates (net outflows) → Tug of war
4. Weak currency → Imported inflation → Government spends more on subsidies → Fiscal deficit worsens

This is why macro instability is self-reinforcing. Breaking the loop requires structural reforms (boost exports, cut wasteful spending).

Sector-Level Impact Matrix

| Macro Scenario | Winners | Losers | |---|---| | Rupee depreciates 5% | IT, Pharma exporters | Airlines, Oil retailers | | Fiscal deficit widens | Defensive FMCG | Capex-heavy infra, banks | | Trade deficit narrows | Domestic cyclicals | Import-dependent tech |

Imagine your family (country) has a monthly budget. Currency is like exchange rate when you trade chocolates with your friend — if your chocolates are tastier (economy strong), friends give more of their chocolates per yours (currency appreciates).

Trade deficit is when your family buys ₹10,000 groceries from outside but sells only ₹7,000 homemade pickles → You owe ₹3,000. If this happens every month, neighbors start doubting if you can pay back → Your "currency" (reputation) drops.

Fiscal deficit is when your parents spend ₹15,000 but earn only ₹12,000 → They borrow ₹3,000 from the bank. Next year, they pay ₹500 interest + still need to borrow more → Debt piles up. Eventually, the bank charges higher interest (crowding out) → Your parents can't lend you money for a bicycle (less investment).

For stocks: If family borows too much, bicycle shop (L&T) won't sell bikes → Their profit drops → Stock falls!

Common Mistakes & Fixes

Why it feels right: Imports become expensive, inflation rises, feels like poverty.

Steel-man: Weak currency DOES hurt in the short term — oil/electronics cost more, real wages drop.

The fix: Medium-term, weak currency bosts exports (Make in India becomes competitive globally), attracts FDI (foreign investors get more rupees per dollar), and reduces trade deficit. India's 2013-2014 rupee fall to₹68 → Export surge, current account improved.

When it's actually bad: If economy is import-dependent for essentials (oil, food) with no export capacity → Pure inflation with no offset (Zimbabwe, Venezuela).

Why it feels right: Personal debt is bad, government debt seems the same.

Steel-man: Wasteful spending (subsidies to loss-making PSUs, populist frebies) IS bad and crowds out productive investment.

The fix: Not all deficits are equal:

• Bad deficit: Revenue expenditure (salaries, subsidies, pensions) → No asset creation
• Good deficit: Capital expenditure (highways, ports, digital infra) → Multiplier effect on GDP

Example: India's FY25 capex ₹11.1 LC (23% of expenditure) → Roads, railways → Private sector benefits (faster logistics) → GDP grows 1.5x the spend (multiplier = 1.5).

Keynes: In recession, government SHOULD run deficits to boost demand → Countercyclical policy.

Red line: Deficit >6% for 5+ years → Debt spiral (interest payments consume revenue).

Why it feels right: If imports > exports, seems like our products are inferior.

Steel-man: Persistent deficits CAN signal structural issues (low productivity, poor quality).

The fix: Composition matters:

• Bad deficit: Import consumer goods we can make domestically (China imports to India: toys, electronics) → Job losses
• Acceptable deficit: Import capital goods/tech we CAN'T make (semiconductors, precision machinery) → Build capacity

USA paradox: Largest trade deficit globally ($948B in 2023) but strongest economy — because:

1. Imports are consumption goods (high living standards)
2. Financed by issuing reserve currency (dollar) → No currency crisis
3. Exports high-value services (finance, tech IP, Hollywood)

India lesson: Our deficit is 60% oil/gold (inelastic, no choice) → Not a competitiveness issue, it's a resource issue. Focus: Boost services exports (already $322B, growing12% YoY).

Mnemonic

• Ca: Currency appreciation → Exporters cry, importers smile
• T: Trade deficit → Rupee pressure, forex reserves drain
• F: Fiscal deficit → Crowding out, rates rise
• Dive: Deficits interconnect (twin deficits loop)
• Deep: Deep dive into sectoral impact before investing

#flashcards/stock-market

What is the real exchange rate formula and why do we adjust for inflation? :: Real Exchange Rate = Nominal Rate × (Foreign Price Level / Domestic Price Level). We adjust because if India has 10% inflation and US has 2%, ₹1 buys 10% less domestically, so nominal rate doesn't reflect true purchasing power parity.
