Singapore T-Bill Allotment & Yield Calculator 2026 — 6-Month & 1-Year MAS Auction Cut-Off Yield, Competitive vs Non-Competitive Bid Allotment, T-Bill Price & Effective Interest Rate, CPF-OA Break-Even Analysis

Singapore Treasury Bills (T-Bills) are short-term government securities issued by MAS (Monetary Authority of Singapore). They work as discount instruments: you pay less than face value today; you receive the full face value at maturity; the difference is your interest income. Key features: government backing: full Singapore government guarantee, zero default risk, AAA-rated; tenors: 6-month (BS-series, ~182 days) and 1-year (BY-series, ~364 days); minimum: S$1,000 per T-Bill, in multiples of S$1,000; non-competitive maximum: S$1,000,000; price mechanism: set by auction — the cut-off yield determines the price you pay; not tradeable: individual investors cannot sell T-Bills on the secondary market before maturity (unlike institutional investors who can trade on the SGS secondary market); available to: Singapore citizens and PRs; also available to foreigners (unlike SSBs); also available via CPF-OA through CPFIS; interest payment: no semi-annual payment — you receive the full discount at maturity; this is the key difference from SSBs (which pay semi-annually). Example: S$10,000 face value, 6-month T-Bill, cut-off yield 3.08%; price paid = S$10,000 × (1 − 3.08% × 182/360) = S$9,844.40; maturity: receive S$10,000; interest earned: S$155.60.

Competitive vs non-competitive bids in Singapore T-Bill auctions: non-competitive bid: you accept whatever cut-off yield MAS determines at the auction; always allotted up to S$1,000,000 per individual; you never know the exact yield in advance (find out when auction results are announced); best for: retail investors who want guaranteed allotment at market rate; competitive bid: you specify the exact yield (in increments of 0.01%) you are willing to accept; allotment depends on the auction result: if your yield ≤ cut-off yield: fully allotted at the cut-off yield price; if your yield = cut-off yield: pro-rated (may receive partial allotment); if your yield > cut-off yield: zero allotment; important: in Singapore’s uniform-price (Dutch) auction, ALL competitive bidders who are allotted receive the SAME cut-off yield price — NOT their individual bid yield; so there’s no yield advantage to bidding a lower yield; the only reason to bid a lower yield competitively is to increase the probability of allotment — which non-competitive bids do automatically; key insight: for individual Singapore investors with amounts under S$1,000,000, non-competitive bidding achieves the same outcome as competitive bidding (at or below cut-off) — with guaranteed allotment and no risk of missing the auction. Competitive bids make sense for: institutional investors who have a minimum required yield; investors who want to participate only if the yield exceeds a certain threshold and are willing to accept zero allotment otherwise.

Singapore T-Bill price calculation 2026: T-Bills use the bank discount method with a 360-day year convention (standard for money market instruments). Price formula: Price = Face Value × (1 − Yield × Days/360). Example: 6-month T-Bill, face S$10,000, cut-off yield 3.08%, tenor 182 days: Price = S$10,000 × (1 − 0.0308 × 182/360) = S$10,000 × (1 − 0.015574) = S$10,000 × 0.984426 = S$9,844.26. Interest earned = S$10,000 − S$9,844.26 = S$155.74. Effective simple rate (365-day, for comparison with FDs and SSBs): Effective Rate = (Interest / Price) × (365 / Days) = (S$155.74 / S$9,844.26) × (365/182) = 1.5818% × 2.0055 = 3.171% p.a. Why the effective rate differs from the discount yield: the discount yield uses face value and 360 days as the base; the effective simple return uses actual price paid and 365 days; the effective rate is ALWAYS higher than the discount yield; for a 3.08% discount yield on a 6-month T-Bill: effective rate ≈ 3.17% — this is the true return on invested capital; when comparing T-Bills to fixed deposits: always compare on the same 365-day simple rate basis; T-Bill quoted discount yield slightly understates the true return vs FD rates. Quick rule of thumb: T-Bill effective rate ≈ discount yield × 365/360 × face/(face − discount) ≈ discount yield × ~1.03 for 6-month T-Bills at typical 2026 yield levels.

Singapore T-Bill application process 2026: step 1 — ensure you have a CDP account: your CDP (Central Depository) account is where T-Bills are held; DBS/POSB, OCBC, and UOB automatically link your bank account to CDP; if you’ve never checked: log into internet banking and look under investments — you should see a CDP section; step 2 — check the auction calendar: MAS announces upcoming T-Bill auctions at mas.gov.sg/bonds-and-bills; for 6-month T-Bills: roughly every 2 weeks; for 1-year T-Bills: monthly; announcement includes the auction date and issuance size (not the yield — that’s determined at the auction); step 3 — apply through internet banking: DBS/POSB: “Invest” → “Singapore Government Securities” → “T-Bills”; OCBC: “Wealth” → “Singapore Government Securities” → “Apply for T-Bills”; UOB: “Invest” → “Bonds and T-Bills”; select: tenor (6-month or 1-year); application amount (face value in S$1,000 multiples); bid type: non-competitive (recommended for retail) or competitive (specify yield); application is typically completed in under 2 minutes; the S$2.00 application fee is deducted immediately; your bank account is debited by the price amount (not face value) on settlement day; step 4 — check results: auction results announced on MAS website usually Thursday afternoon; your bank portal shows allotment status; step 5 — hold to maturity: no action needed; face value deposited into your bank account at maturity; for CPFIS T-Bills: apply through the same banks but navigate to the CPFIS portal; funds deducted from CPF-OA; maturity proceeds return to CPF-OA.

Oversubscribed T-Bill auctions in Singapore 2026: non-competitive bids: are ALWAYS allotted in full, regardless of oversubscription; MAS first sets aside the non-competitive allotment from the total issuance; individual non-competitive limit: S$1,000,000; oversubscription doesn’t affect non-competitive bids (unlike SSBs, which are pro-rated across all bidders); competitive bids — what happens in oversubscription: after the non-competitive allocation, the remaining T-Bill supply is filled by competitive bids from lowest yield to highest; the cut-off yield is the highest yield at which the remaining supply is fully allocated; bidders at the cut-off yield are pro-rated (partial allotment); bidders above the cut-off yield receive zero allotment; bidders below the cut-off yield are fully allotted; strong oversubscription → lower cut-off yield (prices higher, investors accepting lower returns due to high demand); weak demand → higher cut-off yield (issuers must offer more to attract buyers). Real Singapore example: 6-month T-Bill auction with S$5B issuance: S$1B non-competitive bids → all allotted; S$4B remaining for competitive bids; S$7B in competitive applications; cut-off determined at yield where S$4B of competitive bids are filled; bidders below cut-off: fully allotted at cut-off yield; bidders at cut-off: pro-rated (some receive partial allotment); bidders above cut-off: zero allotment, S$2 fee forfeited. What this means for Singapore retail investors: since non-competitive bids are always allotted and receive the cut-off yield: oversubscription is irrelevant to non-competitive bidders; the only impact is indirect: higher oversubscription → lower cut-off yield → you receive slightly less interest on non-competitive bids.

T-Bill early exit options for Singapore retail investors 2026: individuals CANNOT sell T-Bills on the secondary market: unlike institutional investors who can trade SGS (Singapore Government Securities) on the secondary market, retail T-Bill holders cannot sell their T-Bills before maturity; T-Bills are not listed on SGX for retail trading; there is no redemption facility (unlike SSBs which allow monthly redemption at full face value); what this means practically: once you apply for and receive a T-Bill: you hold it to maturity; you cannot access the funds before the maturity date; if you need liquidity: you’d need to use other funds; this is the key disadvantage of T-Bills vs SSBs (SSBs can be redeemed any month); managing T-Bill liquidity in Singapore: strategy 1 — T-Bill ladder: instead of putting S$100,000 into one T-Bill, buy S$50,000 in the current auction and S$50,000 in the next auction (2 weeks later for 6-month T-Bills); this way, you have a T-Bill maturing every 2 weeks, providing periodic liquidity; strategy 2 — keep a liquidity buffer: always keep 1–2 months of emergency funds in a high-interest savings account or SSB; use T-Bills only for the portion you’re confident won’t be needed for 6 months; strategy 3 — combine SSBs and T-Bills: SSBs for the “maybe need” portion (can redeem any month); T-Bills for the “definitely won’t need” portion (higher yield during high-rate environments); CPF-OA T-Bills: even more illiquid (the CPF-OA itself has restrictions on withdrawal), but this is typically for the retirement savings portion where long-term illiquidity is acceptable.

Singapore T-Bill tax treatment 2026: for Singapore individual investors: T-Bill income (the discount) is tax-exempt; you do NOT need to declare T-Bill income in your IRAS annual income tax return; this applies to both 6-month and 1-year T-Bills; applies whether purchased via regular bank account or via CPFIS; applies to Singapore citizens, PRs, and foreigners resident in Singapore; for Singapore companies and entities: T-Bill income may be subject to tax as part of business income; consult a corporate tax advisor; specifically: if T-Bills are held as a business asset, the discount income flows through to the P&L; if held for investment purposes by a company: check your specific situation with a CPA or tax advisor; comparison with other instruments in Singapore: SSBs: tax-exempt for individuals; SGS bonds: tax-exempt for individuals; bank fixed deposits: generally tax-exempt for individual Singaporeans under current IRAS rules (Singapore does not impose personal income tax on interest income from Singapore bank deposits for residents); foreign bonds: interest income from foreign bonds may be taxable — check with IRAS; the bottom line: all Singapore government securities (T-Bills, SSBs, SGS bonds) are tax-exempt for individual investors. This is a key advantage vs corporate bonds, some REITs, and foreign investments. When comparing T-Bill yields to any taxable investment: adjust the taxable return by your marginal tax rate; for a 22% marginal tax rate investor: a 4% taxable yield is equivalent to only 3.12% after tax; the T-Bill’s 3.17% effective yield is more competitive against taxable instruments than the headline numbers suggest.

CPF-OA T-Bill break-even rate calculation Singapore 2026: the break-even concept: your CPF-OA earns 2.5% p.a. guaranteed; when you invest CPF-OA in T-Bills via CPFIS, you forfeit approximately 1 month of CPF-OA interest during the transition (application, deduction, settlement); this transition cost is the basis of the break-even calculation; formula: break-even T-Bill yield = CPF-OA rate + (1 month CPF-OA interest ÷ total investment) × 100; = 2.5% + (principal × 2.5% ÷ 12 ÷ principal) × 100; = 2.5% + (2.5/12)%; ≈ 2.5% + 0.208% ≈ 2.708%; this break-even is the SAME for all investment amounts (the formula simplifies to be independent of principal); how to use the break-even: if current 6-month T-Bill cut-off > 2.708%: invest CPF-OA via CPFIS — you earn more than staying in CPF-OA; if current 6-month T-Bill cut-off < 2.708%: keep in CPF-OA — the 1-month transition cost makes T-Bill inferior; 2026 context: Singapore 6-month T-Bill cut-offs have generally been in the 3.0%–3.5% range, well above the 2.708% break-even; CPF-OA T-Bill investment has been worthwhile for most of 2024–2026 at these levels; important qualifications: DON'T invest CPF-OA funds needed for HDB mortgage payments in the next 6 months; T-Bill matures in 6 months; if you need those funds for the mortgage in Month 4, you're stuck; the break-even assumes a clean 6-month T-Bill hold with maturity back to CPF-OA; the extra interest earned = (T-Bill yield − 2.708%) × investment × 6/12; for S$50,000 at T-Bill 3.15% vs break-even 2.708%: extra = (3.15% − 2.71%) × S$50,000 × 0.5 = 0.44% × S$25,000 ≈ S$110 extra over 6 months.

T-Bill vs SSB decision framework Singapore 2026: choose T-Bills when: T-Bill cut-off yield is meaningfully higher than SSB Year 1 rate (typically by 0.2%+); you are confident you won’t need the funds for 6 months (no early exit); you want maximum flexibility to redeploy at new rates every 6 months (T-Bills roll over — if rates rise, you capture the higher rate at next auction); choose SSBs when: you want the ability to redeem at any time without penalty (SSB gives you monthly flexibility, T-Bill doesn’t); SSB 10-year average rate is attractive for medium-to-long-term savings; you don’t want to manage bi-weekly T-Bill applications (SSB is “set and forget” for up to 10 years); you’re investing via CPF-OA and the SSB rate exceeds the CPF-OA break-even (similar calculation to T-Bill break-even); you prefer interest paid semi-annually (SSB pays June/December; T-Bill pays at maturity only); combined strategy (most commonly used by Singapore investors): T-Bills for the “core” fixed-income portion: the portion you’re confident won’t be needed for 6 months; maximises yield during high-rate environments; SSBs for the “flexible” portion: money you might need — can redeem any month; both for the “always safe” risk profile: no credit risk, no market risk, government guarantee; when T-Bill rate is much higher than SSB Year 1 rate: favour T-Bills heavily; when the rates converge or SSB 10-yr average is attractive: consider SSBs for longer-term portions; Singapore investors often split 60/40 or 70/30 between T-Bills and SSBs depending on their view of interest rate direction.

Reading MAS T-Bill auction results Singapore 2026: where to find: mas.gov.sg/bonds-and-bills → “Singapore Government T-Bills” → “Past Results”; also disseminated via MAS newswire and major Singapore financial news outlets (Straits Times, Business Times, Channel News Asia business section); key data in the results announcement: total amount applied for: sum of all non-competitive and competitive bids; tells you if the auction was oversubscribed (demand > issuance); total amount allotted: equals the issuance size (always fully issued); non-competitive amount: total allotted to non-competitive bids; cut-off yield: the most important number — the yield at which MAS stopped accepting competitive bids; all successful bidders receive this yield’s corresponding price; allotment at cut-off: percentage allotted to competitive bids AT the cut-off yield; 100% = no oversubscription at cut-off (all bids at cut-off received full allotment); 50% = moderate demand at cut-off; 10% = very heavy demand at cut-off (most bid much lower); competitive bids allotted at below cut-off: the amount received by investors who bid BELOW the cut-off (fully allotted); total allotment: sum of above; cover ratio: total applied / total allotted — higher ratio = stronger demand; example of reading results: Issuance S$5.3B; Total applications S$8.7B (cover ratio 1.64×); Cut-off yield 3.08%; Allotment at cut-off: 45%; this tells you: strong demand (1.64× oversubscribed at auction); competitive bids exactly at 3.08% only got 45% allotment; anyone who bid above 3.08% got zero; non-competitive bids: 100% allotted; this particular auction had meaningful oversubscription, pushing the cut-off lower than some might have expected.

T-Bill eligibility for foreigners in Singapore 2026: unlike SSBs (which are restricted to Singapore citizens and PRs), Singapore T-Bills are available to: Singapore citizens: yes; Singapore Permanent Residents (PRs): yes; foreigners (Employment Pass, S-Pass, long-term visit pass, etc.): YES — foreigners can buy Singapore T-Bills; non-residents (investing from overseas): technically possible through a local bank account, but requires a CDP account and Singapore bank account; practical requirements for foreigners in Singapore: a Singapore bank account (DBS, OCBC, or UOB); a CDP account (linked to the bank account — usually set up automatically); physical presence in Singapore is not strictly required for the application (can apply online); a valid identity document; NRIC for citizens/PRs; passport and work pass for foreigners; SingPass access for online banking (available to EP/S-Pass holders); how foreigners in Singapore access T-Bills: through DBS/POSB, OCBC, or UOB internet banking (exactly the same process as citizens); the bank verifies identity through existing KYC processes; foreigners CANNOT buy SSBs but CAN buy T-Bills — this is a common source of confusion; for foreigners who have CPF contributions (only citizens and PRs have CPF): T-Bills via CPFIS — only for citizens and PRs; for foreigners working in Singapore: T-Bills are an excellent complement to SRS (Supplementary Retirement Scheme) accounts and regular savings; compare the T-Bill yield against your home country’s risk-free rate when deciding whether T-Bills make sense for your overall portfolio.

Singapore T-Bill investment strategies 2026: strategy 1 — the “core safe yield” strategy: invest a fixed amount (e.g., your 6-month emergency fund above your bank account qualifier threshold) in T-Bills every 6 months; use non-competitive bids; reinvest at maturity; this ensures your safe cash always earns near-market risk-free yields; strategy 2 — the “T-Bill ladder” strategy: split your T-Bill allocation across multiple auctions (e.g., every 2 weeks for 6-month T-Bills); example: S$100,000 → apply S$25,000 every 2 weeks for 4 consecutive auctions; result: T-Bills maturing every 2 weeks throughout the year; provides continuous liquidity without keeping cash idle; strategy 3 — the “T-Bill + SSB barbell”: short-duration T-Bills for the highest current yields; SSBs for medium-to-long-term capital at step-up rates; serves both liquidity needs and long-term rate security; strategy 4 — the “CPF-OA optimizer”: check each 6-month T-Bill auction cut-off vs CPF-OA break-even (~2.71%); when cut-off > 2.71%: invest excess CPF-OA (above mortgage needs) via CPFIS; when cut-off < 2.71%: keep in CPF-OA; this works best in high-rate environments (as seen in 2023–2026); strategy 5 — the "rate direction bet": if you believe rates will RISE further: favour T-Bills over SSBs (roll over at higher rates every 6 months); if you believe rates will FALL: favour SSBs (lock in current rates for up to 10 years before rates drop); SSBs purchased in a high-rate environment continue earning step-up rates even if new SSB rates fall; 2026 Singapore context: with MAS monitoring global rate trends, the T-Bill vs SSB decision depends on your personal rate outlook and liquidity needs — this calculator helps you evaluate the T-Bill component specifically.

Singapore T-Bill investment minimums and limits 2026: minimum investment: S$1,000 per T-Bill; all applications must be in multiples of S$1,000; increments: there is no maximum number of T-Bills you can hold; but non-competitive bids are capped at S$1,000,000 per application; you can apply for as many separate T-Bill auctions as you wish; minimum practical amount: the S$1,000 minimum with S$2.00 application fee makes T-Bills accessible to all Singapore investors; at S$1,000 face value and 3.08% cut-off yield for 6 months: interest earned ≈ S$15.57; the S$2.00 fee represents 12.9% of the interest earned; for small amounts, the S$2.00 fee may be disproportionate; breakeven amount where S$2.00 fee is less than 1% of interest: approximately S$26,000 (at 3.08% for 6 months, interest = S$403; S$2 = 0.5%); practical minimum recommendation: S$5,000–S$10,000+ to make the S$2 fee negligible relative to interest earned; S$5,000 at 3.08% for 6 months: interest ≈ S$77.87; fee = 2.57% of interest (still manageable); maximum for non-competitive bids: S$1,000,000 per individual per auction; there is no aggregate holding limit for T-Bills (unlike SSBs which cap at S$200,000); you can hold multiple T-Bills from different auctions simultaneously; example: S$200,000 in 6-month T-Bill from January auction + S$200,000 from February auction = S$400,000 total in T-Bills; this is perfectly allowed and common for high-savings Singapore investors above the SSB limit.

Singapore T-Bill pricing: bank discount rate vs effective rate 2026: why there are two rates: T-Bills quote yields using the bank discount convention (a legacy of US money market conventions); this convention uses 360 days and calculates yield based on face value; the effective simple rate uses 365 days and calculates yield based on price paid (the actual money invested); which one matters: the bank discount yield: this is what MAS quotes and what you see in auction results; it’s the conventional T-Bill yield; the effective simple rate: this is the true annual return on the money you invested; this is what you should compare against FDs, SSBs, and CPF-OA rates; the difference (worked example at 3.08% cut-off, 182 days): bank discount price per S$1,000 = S$1,000 × (1 − 3.08% × 182/360) = S$984.43; bank discount rate: 3.08% (quoted); interest earned: S$15.57 per S$1,000 face; effective simple rate: (S$15.57/S$984.43) × (365/182) = 1.5818% × 2.0055 = 3.171% p.a.; the effective rate (3.171%) is always slightly higher than the bank discount rate (3.08%) because: the denominator uses the price paid (S$984.43), not face value (S$1,000); the numerator uses 365 days, not 360; practical implication: when comparing T-Bill yield to fixed deposit rates: FD rates are quoted as simple annual interest on the amount deposited; T-Bill discount rate is NOT the same metric; always convert T-Bill to effective rate first; at typical 2026 levels (3.0%–3.5% discount), the effective rate is approximately 3% – 3.5% × (365/360) × (face/price) ≈ 3%–3.5% × 1.03 – in simpler terms, add approximately 0.1% to the T-Bill discount rate to get the effective comparable rate.

Singapore T-Bill cut-off yield history and 2026 context: this calculator uses indicative rates; always check the latest actual cut-off yields at mas.gov.sg/bonds-and-bills for current auctions. Historical context (approximate, verify at MAS for exact figures): 2022 period: 6-month T-Bill yields rose from near 0% to 4%+ as global interest rates surged; Singapore followed global tightening; 2023 period: yields stabilised in the 3.5%–4.0% range; significant investor interest; SSB rates also elevated; several auctions were heavily oversubscribed, pushing cut-offs lower; 2024 period: yields began moderating as global rate hike cycles peaked; 6-month T-Bill cut-offs in the 3.2%–3.8% range; 2025–2026 indicative range: approximately 2.8%–3.5% for 6-month T-Bills; rate direction depends on MAS policy, US Fed Reserve moves, and Singapore economic conditions; MAS manages the SGD exchange rate (not interest rates directly, unlike most central banks); Singapore interest rates are highly correlated with US rates; if US Fed Reserve cuts rates: Singapore T-Bill yields typically fall; if US inflation persists and Fed keeps rates elevated: Singapore T-Bills remain competitive; for 2026 financial planning: model scenarios at both higher rates (3.3%–3.5%) and lower rates (2.8%–3.0%) to stress-test your strategy; this calculator allows you to input different cut-off yields to see how your interest income changes across scenarios. Always verify the most current auction results at mas.gov.sg before making investment decisions.

Singapore T-Bill ATM application vs internet banking 2026: both methods are valid and result in the same allotment outcome. ATM application (DBS/POSB, OCBC, UOB): available at most bank branches with ATMs; navigate to: “More Transactions” → “SGS Bonds” or “Singapore Government Securities” → “T-Bills” (menu location varies by bank); enter: application amount, bid type (competitive or non-competitive), bid yield (if competitive); S$2.00 fee deducted from account; limitations of ATM: lower transaction limit compared to internet banking (typically capped at S$100,000 at ATM vs S$1,000,000 via internet banking for non-competitive); longer process (navigating menus vs 3 clicks online); not all ATMs support T-Bill applications (typically need a full-service ATM); internet banking application (recommended): DBS/POSB ibanking or DBS digibank app; OCBC internet banking or OCBC Digital app; UOB internet banking or UOB TMRW app; faster (2–3 minutes); higher limits (up to S$1,000,000 for non-competitive via internet banking); can be done from anywhere, 24/7 during the application window; app-based: all three banks have mobile apps that support T-Bill applications; DBS digibank app: “Invest” → “T-Bills”; OCBC Digital: “Wealth” → “Bonds & T-Bills”; UOB TMRW: “Investment Products” → “Bonds”; which is better: internet banking or mobile app is recommended for most Singapore investors; faster, higher limits, available from anywhere; ATM is a valid backup if you don’t have internet banking access; for large applications (above S$100,000): internet banking is necessary as ATM limits may not be sufficient.
