Derived indicators
Every other series on PakDataHub is a figure a publisher printed. The derived layer is the exception, and it's labelled as one. These are indicators no publisher prints, computed by PakDataHub from official series with a published formula: long spliced histories, real interest rates, spreads, import cover, rolling totals, city-level essentials inflation and fund-category yields.
- Labelled.
source is PakDataHub, and the catalog record and every series response carry a derived object with the method and the input series:
"derived": {
"method": "Ex-post real policy rate = SBP policy rate at month-end − national CPI inflation (YoY) for the month ...",
"inputs": ["rates.reverse_repo", "rates.policy_target", "rates.policy", "inflation.cpi.national.yoy", "..."],
"version": 1
}
- Reproducible. Each formula uses only official series you can fetch yourself, and each one is unit-tested against hand-computed values.
- Kept current. The layer is recomputed twice a day, after its inputs land. If an input is revised, the derived value is revised too, and the revision is recorded like any other (vintages).
- On every plan, with the usual history window per plan.
Official series are never modelled. A derived series sits next to them; it doesn't replace any of them.
#Rates
| Series |
What it is |
Method |
rates.policy.history |
SBP policy rate at each month-end, since 1956 |
The reverse repo rate (then the policy rate) until the interest-rate corridor of 25 May 2015, the policy (target) rate since |
rates.real.policy |
Real policy rate |
Policy rate at month-end − national CPI inflation (YoY) |
rates.real.kibor_3m |
Real 3-month KIBOR |
Monthly average of the daily 3-month KIBOR offer (months with ≥10 fixings) − CPI inflation (YoY) |
rates.spread.kibor_3m_policy |
3-month KIBOR minus the policy rate, daily since 2005 |
KIBOR 3M offer − the policy rate in effect that day |
rates.spread.tbill_3m_policy |
3-month T-bill cut-off minus the policy rate, per auction since 2004 |
Cut-off yield − the policy rate in effect on the auction date |
rates.spread.pkrv_10y_3m, rates.spread.pkrv_10y_1y |
Yield-curve slope, daily since 2022 |
PKRV 10Y − PKRV 3M (or 1Y). Negative = inverted curve |
#Prices
| Series |
What it is |
Method |
inflation.cpi.national.yoy.long |
National CPI inflation (YoY) in one series from 1965 |
PBS's CPI YoY where published (Jul 2017 →), else SBP's base-2015-16 national CPI YoY (Jul 2016 →), else SBP's historical general CPI YoY (1965 → Apr 2020). Base years differ across the splice points |
prices.essentials_inflation.<city> |
Weekly essential-goods inflation (YoY), national and 17 cities, from July 2024 |
The geometric mean, over the PBS SPI essential items priced in both weeks (at least 15), of each item's price against 52 weeks earlier: a Jevons index of 52-week price changes, so it doesn't depend on any base week |
#External
| Series |
What it is |
Method |
external.import_cover_months |
Months of imports SBP's reserves pay for |
SBP's total reserves (gold and foreign exchange) at month-end ÷ the average monthly import bill (goods and services, BOP) of the latest three months |
remittances.total.12m |
Workers' remittances, 12-month rolling total (US$ mn) |
Sum of the latest 12 consecutive months. It's free of Ramadan/Eid seasonality |
fx.spread.interbank.usd |
USD/PKR interbank bid-offer spread (rupees), daily |
SBP weighted-average interbank offer − bid |
#Funds and payments
| Series |
What it is |
Method |
funds.category.money_market.yield_30d, funds.category.shariah_money_market.yield_30d, funds.category.income.yield_30d |
What a typical fund in the category is earning, weekly |
Median across the category's funds of each fund's latest MUFAP 30-day return (annualised, as MUFAP publishes it) in the week. Weeks with fewer than 5 funds are skipped |
funds.category.equity.return_1y, funds.category.shariah_equity.return_1y |
Typical 1-year equity-fund return, weekly |
Median of each fund's latest MUFAP 365-day return in the week |
payments.raast.share_of_retail_value |
Raast's share of retail payments value, quarterly |
Raast transaction value ÷ total retail payments value (SBP Payment Systems Review) |
