How to buy T-bills and PIBs through InvestPak
InvestPak is SBP's official portal for digital IPS onboarding, primary-auction bids and secondary-market requests. Eligibility, denominations, fees and settlement remain instrument- and bank-specific.
Straight to it: Register on InvestPak, link a PKR bank account, request or link an IPS account, and use the portal for eligible primary- or secondary-market instructions. The financial institution still verifies the account and processes requests.
- An IPS account is required to hold marketable Government of Pakistan securities; InvestPak can initiate the opening request
- Use the portal's live auction calendar, results and indicative quotes instead of a rate copied into an article
- Compare direct ownership with funds and CDNS products on denomination, fees, liquidity, tax and legal structure, not account size alone
Government securities can be bought at SBP auctions or in the secondary market and held in an IPS account. InvestPak digitises registration, IPS requests, auction bids and secondary-market requests for eligible bank-account holders. This guide explains the workflow and the risks without ranking it against another product.
01What are T-bills and PIBs?
Market Treasury Bills (T-bills) are short-term government debt, commonly issued in 3-month, 6-month and 12-month tenors. They are zero-coupon instruments sold at a discount to face value; the annualised difference between purchase and maturity value is the yield. The InvestPak instrument pages provide current denominations and auction data.
Pakistan Investment Bonds (PIBs) are longer-term securities. Fixed-rate PIBs and several floating-rate structures have different coupon, reset, tenor and auction rules. Use the current instrument page for the exact series rather than assuming every PIB has the same cash-flow schedule.
These are obligations of the Government of Pakistan, not bank deposits. Sovereign credit does not remove inflation, market-price, liquidity, reinvestment, operational or tax risk. A security sold before maturity may realise more or less than its purchase price.
02How yields track the SBP policy rate
Auction yields are market outcomes, not the SBP policy rate. Compare the relevant cut-off yield, weighted-average yield, issue date and maturity in InvestPak's auction results. A difference between a longer-tenor yield and the policy rate can reflect many expectations and risk premiums; it is not a certain forecast of the next policy decision.
Tenor changes the risk profile. Document these scenarios before comparing instruments:
- Reinvestment: a short security matures sooner, and the next available yield may be higher or lower.
- Price sensitivity: a longer fixed-rate security generally moves more when market yields change.
- Cash-flow timing: maturity and coupon dates must match the date funds may be needed.
Do not choose a tenor from a single rate forecast. Stress-test higher and lower yields, early sale, inflation and the inability to reinvest at the original rate.
03What is an IPS account?
Government securities are held in book-entry form through an Investor Portfolio of Securities (IPS) account. InvestPak's FAQ describes the IPS account as mandatory for buying government securities and says it can be opened through a commercial bank, with the request initiated on the portal.
Participating institutions, conventional and Islamic instruments, minimum denominations and fees vary. Use the current institution and instrument information on InvestPak and obtain the bank's written fee schedule before submitting a request.
The official individual-investor guidelines describe portal registration, IBAN validation, contact verification, two-factor authentication and the bank's acceptance or follow-up process. The bank may require additional KYC evidence.
Do not assume the account is free or that every bank applies the same minimum. Include custody, transaction, spread and transfer charges in the net-return calculation.
04Primary auctions vs the secondary market
There are two ways to acquire government securities, and your bank handles both through the same IPS account.
1. Primary auctions
InvestPak publishes active auctions, calendars, results and bid guidance. Competitive and non-competitive bids have different eligibility, pricing and limits, which also vary by instrument. Read the portal's current auction guidelines and the terms of the exact security before entering an instruction.
2. Secondary market purchase
InvestPak can route buy or sell requests to the investor's bank and publishes indicative quotes and benchmarks. A quote is not the face value: price, accrued profit, yield, settlement date, spread and fees all affect cash paid or received. Confirm the executable terms before submitting.
05InvestPak onboarding and transaction flow
- Register on the official portal. Use contact details associated with the bank account and complete the required verification.
- Add the PKR bank account. InvestPak validates the IBAN and sends the onboarding request to the financial institution.
- Request or link an IPS account. The bank may accept, reject with a reason or request further action.
- Read the exact instrument page. Record denomination, auction method, bid limits, cash-flow rules, tax and maturity.
- Review live market data. Use the current auction calendar, results and indicative quotes; save the observation date.
- Enter the instruction. Confirm security, face amount, bid type, funding balance, portal cut-off and any bank fee before authorising with the required security controls.
- Keep the confirmation. Reconcile cash debited, securities credited, price, yield, settlement date and tax records.
- Plan maturity or sale separately. A new purchase, rollover or secondary-market sale is a new decision at then-current rates and prices.
Save the instrument page, auction result, bank fee schedule and transaction confirmation. A sequence of past yields can describe the market but cannot determine which tenor is appropriate or predict the next policy decision.
06T-bills vs National Savings vs money market funds
Direct securities, National Savings products and money market funds have different legal structures. Populate this table from disclosures dated on the day of comparison:
| Feature | T-Bills via IPS | National Savings (CDNS) | Money Market Funds |
|---|---|---|---|
| Practical minimum | Instrument denomination and bank terms | Current CDNS product rules | Fund offering document |
| Current yield anchor | Current auction result or executable quote | Current CDNS published rate | Matched-period MUFAP return and expenses |
| Liquidity | Portal/bank sale process, settlement and market price | Product-specific encashment rules | Fund-specific cut-off and settlement at NAV |
| Effort | InvestPak, IPS and bank processing | CDNS or approved distribution channel | Licensed AMC onboarding and servicing |
| Protection / exposure | Government security; market and sovereign exposure | Government product under its scheme terms | Fund units; portfolio, NAV, fee and liquidity exposure |
A money market fund may hold T-bills alongside bank placements and other permitted instruments; it is not identical to owning one T-bill. Compare its current portfolio, total expense ratio, rating and redemption terms in the offering documents and MUFAP data. For CDNS products, use the current profit-rate page. No fixed account-size threshold makes one structure universally preferable.
07Taxes on T-bill and PIB profit
Returns on government securities are taxed as profit on debt under the Income Tax Ordinance. Your bank deducts withholding tax at source, so the amount hitting your account is already net of tax. Two things to keep in mind:
- ATL status can change withholding. The applicable rate depends on current law and the taxpayer's facts; withholding is not necessarily the final liability.
- Rates change. Use the FBR Tax Year 2027 withholding card and the current Income Tax Ordinance instead of a percentage copied from an older article.
Capital gains on securities sold before maturity are taxable too, under different treatment. Keep your bank's transaction confirmations for return-filing time.
08The risks: what can actually go wrong
Reinvestment risk
A short security matures sooner and its proceeds must be reinvested at whatever yield is then available. That yield may be higher or lower. A longer fixed-rate instrument reduces that reinvestment frequency but adds greater price sensitivity and a longer commitment.
Price risk on PIBs sold before maturity
A fixed-rate PIB held to maturity follows its contractual cash flows, subject to issuer terms. Sold early, it receives the market price. When market yields rise, an existing fixed-rate bond's price generally falls, with greater sensitivity at longer duration. Floating-rate instruments have different reset and spread risks rather than eliminating risk.
Inflation risk
A nominal rupee cash flow does not guarantee purchasing power. Compare cash flows with CPI from the Pakistan Bureau of Statistics over matched periods and model multiple future inflation paths. This calculation does not by itself establish an allocation to another asset.
Record the exact security, price, yield, maturity, cash-flow dates, fees, tax assumption and early-sale scenario. Compare alternatives using disclosures from the same date. InvestPak improves access; it does not make a security suitable or its return certain.
