# BOI Economic Data

## Instructions

### Step 1: Identify the Data Type
Ask the user what economic data they need:

| Data Type | Hebrew | Source | Update Frequency |
|-----------|--------|--------|-----------------|
| Interest rate | ריבית בנק ישראל | BOI Monetary Committee | Announced ~6 times/year |
| Exchange rates | שערי חליפין (שער יציג) | BOI | Daily (published ~16:00) |
| CPI (Consumer Price Index) | מדד המחירים לצרכן | CBS (Lishkat HaStatistika) | Monthly (around 15th of following month) |
| Inflation expectations | ציפיות אינפלציה | BOI | Monthly |
| Government bonds yield | תשואת אג"ח ממשלתי | BOI / TASE | Daily |
| Monetary aggregates | אגרגטים מוניטריים | BOI | Monthly |

### Step 2: Fetch Data from BOI API
The Bank of Israel provides public data via REST API at `data.boi.org.il`. Note: API endpoint structure may change, verify current endpoints before use.

**Exchange Rates (Sha'ar Yatzig):**
```
GET https://data.boi.org.il/api/data/EXR?format=json&startperiod={date}&endperiod={date}
```

**Interest Rate:**
```
GET https://data.boi.org.il/api/data/IR_INTEREST?format=json
```

Use `scripts/fetch_boi_rates.py` for simplified data fetching.

### Step 3: Process Exchange Rate Data
BOI publishes representative exchange rates (sha'ar yatzig) daily:

| Currency | Code | Typical Use |
|----------|------|-------------|
| US Dollar | USD | Primary foreign currency, investment pricing |
| Euro | EUR | EU trade, travel |
| British Pound | GBP | UK trade |
| Japanese Yen | JPY | Per 100 JPY |
| Swiss Franc | CHF | Safe haven |

Key points:
- Representative rate published once daily at approximately 16:00
- Used as official rate for tax calculations, contracts, financial reporting
- Weekend and holiday rates use last published rate
- For intraday rates, use forex platforms (BOI rate is indicative)

### Step 4: Analyze CPI Data
The Consumer Price Index (Madad HaMchirim LaTzarchan) from CBS:

| CPI Component | Hebrew | Weight (approx) | Notes |
|---------------|--------|-----------------|-------|
| Housing | דיור | ~25% | Rent component (not home prices) |
| Food | מזון | ~17% | Including dining out |
| Transportation | תחבורה | ~17% | Fuel, public transit, vehicles |
| Education & culture | חינוך ותרבות | ~11% | Tuition, books, entertainment |
| Health | בריאות | ~6% | Medical services, medications |
| Clothing | הלבשה והנעלה | ~3% | Seasonal adjustments |

CPI uses:
- **CPI-linked bonds (Galil):** Index-linked government bonds adjust by CPI
- **Rent adjustments:** Many Israeli leases are CPI-linked (tzmud madad)
- **Tax brackets:** Updated annually by CPI
- **Alimony and legal judgments:** Often CPI-linked

Note: CBS publication schedule may vary. CPI data is typically published around the 15th of the following month, but verify current CBS publication schedules.

### Step 5: Track Interest Rate Decisions
BOI Monetary Committee sets the interest rate:

| Rate Level | Typical Context | Impact |
|------------|----------------|--------|
| Rising | Inflation above target (1-3%) | Higher mortgage rates, stronger NIS |
| Stable | Inflation within target | Predictable borrowing costs |
| Falling | Low inflation or economic slowdown | Lower mortgage rates, weaker NIS |

Historical context helps interpret current decisions. Use `scripts/fetch_boi_rates.py --interest-history` for recent rate changes.

### Step 6: Combine Data for Analysis
Cross-reference multiple data points for comprehensive analysis:
1. **Mortgage planning:** Interest rate + CPI trend + exchange rate outlook
2. **Business planning:** Exchange rate + CPI for cost projections
3. **Investment analysis:** Bond yields + inflation expectations
4. **Import/export pricing:** Exchange rates + CPI for contract negotiations

## Examples

### Example 1: Current Exchange Rate
User says: "What is today's dollar-shekel exchange rate?"
Actions:
1. Run `python scripts/fetch_boi_rates.py --currency USD`
2. Display representative rate (sha'ar yatzig) with date
3. Note: Rate published at approximately 16:00, before that yesterday's rate applies
Result: Current USD/NIS representative rate with context

### Example 2: Interest Rate Impact
User says: "What is the current BOI interest rate and how does it affect mortgages?"
Actions:
1. Run `python scripts/fetch_boi_rates.py --interest`
2. Show current rate and recent history
3. Explain: Variable-rate mortgages (mashkanta priim) directly affected
4. Note: Fixed-rate mortgages set at time of signing, not affected by changes
Result: Interest rate with mortgage impact analysis

### Example 3: CPI Trend for Rent Adjustment
User says: "My lease says rent adjusts by CPI. How much did it go up?"
Actions:
1. Determine: Lease start date and adjustment period
2. Fetch: CPI values for start and current period
3. Calculate: Percentage change = (CPI_current - CPI_base) / CPI_base * 100
4. Apply: New rent = original_rent * (1 + percentage_change / 100)
Result: Exact CPI adjustment with new rent calculation

## Bundled Resources

### Scripts
- `scripts/fetch_boi_rates.py` -- Fetches Bank of Israel data: exchange rates, interest rates, and CPI. Run: `python scripts/fetch_boi_rates.py --help`

### References
- `references/boi-api.md` -- Bank of Israel API endpoints (SDMX format), authentication, rate limits, and data structure. Consult when building integrations or troubleshooting API calls.

## Gotchas
- Agents often query BOI exchange rates for Friday or Saturday, but the representative rate (sha'ar yatzig) is only published on business days (Sunday-Thursday). Use the last available Thursday rate for weekends.
- The BOI SDMX API returns XML by default, not JSON. Agents must either parse XML or add the correct Accept header for JSON format.
- Agents may confuse the BOI representative rate (indicative, published once daily at approximately 16:00) with real-time forex rates. The BOI rate is not suitable for intraday trading decisions.
- CPI data from CBS lags by about 6 weeks: January's CPI is published around February 15th. Agents may try to fetch current-month CPI that does not exist yet.

## Troubleshooting

### Error: "BOI API returned empty data"
Cause: Querying for weekend/holiday date when no rate was published
Solution: BOI publishes rates on business days only (Sunday-Thursday). For Friday/Saturday, use the last published rate (Thursday). Use the API date range query to get the most recent available rate.

### Error: "CPI data not yet available"
Cause: CBS publishes CPI around the 15th of the following month
Solution: If current month's CPI is not available, use the latest published index. Check CBS publication calendar for exact release dates.

### Error: "Exchange rate seems stale"
Cause: Using representative rate before daily publication time
Solution: BOI representative rate is published at approximately 16:00 Israel time. Before that, the previous day's rate is the official rate. For intraday indicative rates, use bank or forex feeds.
