The highest USDT premium recorded by The Crypto Times’ India index is 5.29%, struck at the 8 September 2026 daily fix. A higher premium was reported before the index began publishing: USDT traded at ₹102.88 on 27 June, more than 8.5% above the interbank dollar rate, after the Enforcement Directorate searched crypto payment firms in Bengaluru. The latest fix, on 14 October, was 4.89%.
The archive contains 69 published fixes through 14 October 2026 from the India USDT Premium Index, which began on 9 July 2026. This article ranks the biggest spikes and drops in those fixes and traces each one to a move in the USDT price, the rupee, or both.

What the premium measures
The USDT premium is how much more an Indian buyer pays for one USDT than the USD/INR reference rate implies. A reading of 5% means one USDT cost 5% more rupees than one dollar does at the reference rate.
Each trading day the index samples USDT prices on up to five Indian exchanges between 11:30 and 12:30 IST and takes the median. It compares that price with the latest ECB euro reference rate struck before the fix date, converted to USD/INR, and adjusts for USDT’s own global dollar price. The methodology is public.
The premium has two moving parts. It rises when USDT gets dearer in rupees. It also rises when the dollar reference gets cheaper, because the reference rate sits in the denominator. Several peaks below come from the second effect.
The record before the archive: above 8.5% in June 2026
The Enforcement Directorate (ED) searched six premises in Bengaluru on 17 June 2026 under the Foreign Exchange Management Act. Its press release names five payment firms and describes on-ramp and off-ramp services that convert rupees into stablecoins such as USDT. Its preliminary findings put the contraventions above ₹2,500 crore.
USDT then climbed. The Economic Times reported that over the weekend of 27 June USDT traded at ₹102.88 against an interbank closing rate of ₹94.65, a premium above 8.5% against a usual range of 3% to 4%, as relayed by The Block and CoinDesk. Dividing the two prices gives about 8.7%.
The Block, citing the same report, said non-resident Indians had used USDT in place of bank wires, and that market makers pulled back from buying USDT abroad after the ED statement. That tightened supply on Indian exchanges.
This reading is not directly comparable with the index. It uses the interbank rate, with no ECB reference and no peg adjustment. By the first index fix on 9 July, the premium was 3.40%.
The biggest spikes in the archive and what moved them
Five fixes reached 5% or more, all between 31 August and 9 September 2026.
| Date | Premium | ₹ per USDT | Reference USD/INR (₹) | Exchanges counted |
|---|---|---|---|---|
| 8 Sep 2026 | 5.29% | 99.46 | 94.49 | 4 |
| 9 Sep 2026 | 5.24% | 99.78 | 94.83 | 5 |
| 7 Sep 2026 | 5.05% | 99.25 | 94.49 | 3 |
| 31 Aug 2026 | 5.03% | 100.18 | 95.39 | 4 |
| 4 Sep 2026 | 5.02% | 99.23 | 94.49 | 5 |
31 August to 9 September: the dollar got cheaper while USDT did not
The peak came from the denominator. The reference rate fell from ₹95.39 on 31 August to ₹94.49 on 4 September, the lowest in the archive, and stood at ₹94.49 on 8 September. USDT fell less, from ₹100.18 to ₹99.46, so the gap widened to 5.29%.
A 4 September market report in Telangana Today attributed the rupee’s gains to foreign inflows and risk appetite, with Reserve Bank of India intervention also cited.
At the 8 September fix, ₹1,00,000 bought 1,005.39 USDT worth about ₹94,974 at the reference rate. About ₹5,026 of the outlay was premium.
26 August: a 1.4 point jump in one session
The premium rose from 3.19% on 25 August to 4.60% on 26 August. USDT went from ₹98.77 to ₹99.79, up 1.0%, while the reference rate eased from ₹95.75 to ₹95.42. Most of the move came from the USDT price. The Crypto Times found no public announcement tied to that day.
28 July: the premium rose while the price held
The premium moved from 3.75% on 27 July to 4.44% on 28 July with USDT flat at about ₹100.07. The reference rate fell from ₹96.57 to ₹95.92, a drop of 0.7%. That change alone raised the premium by roughly 0.7 percentage points.
13 and 14 October: back above 4% after the RBI package
The premium went from 2.74% on 12 October to 4.27% on 13 October and 4.89% on 14 October. On 10 October the Reserve Bank of India announced a special window to meet the full daily dollar needs of three state-run oil marketing companies from 12 October.
The reference rate fell about 1% between the 12 and 13 October fixes, from roughly ₹96.7 to ₹95.775, while USDT rose 0.5% to ₹99.74. On 14 October USDT was almost unchanged at ₹99.83 and the implied reference rate fell again, to about ₹95.3. The timing fits the RBI measures, but the index does not establish cause.
A high price is not a high premium
The highest USDT price in rupees, ₹100.44 on 29 September, came with a 4.69% premium, below the September peak. When the rupee is weak, USDT can cost more rupees and still carry a smaller premium.
The sharpest drops
The largest one-session fall was 1.49 points, from 4.49% on 1 October to 3.00% on 5 October. USDT fell from ₹100.08 to ₹99.18, down 0.9%, while the implied reference rate rose about 0.5%, from roughly ₹95.8 to ₹96.3. Only three exchanges counted on 5 October.
The series low came three sessions later. On 8 October the premium was 2.56% with USDT at ₹99.15 and an implied reference rate of about ₹96.7, close to the weakest rupee reading in the archive. The premium fell to its low when the dollar was at its dearest.
Three other declines, each between 0.65 and 0.70 percentage points, followed a similar pattern of a falling USDT price against a steady reference rate: 14 August, 20 August and 14 September.
Why the premium exists
Indian buyers want more USDT than flows in to meet them. The index FAQ says India buys more crypto than it sells, so buyers pay more rupees per token than the dollar rate implies.
Tax rules add friction. The Income Tax Department sets a flat 30% tax, plus surcharge and cess, on income from transferring virtual digital assets, plus 1% tax deducted at source on transfer payments above a threshold. The index FAQ lists these rules and cautious banking as limits on how much new USDT arrives.
Enforcement can tighten supply within days, as the June searches did. The rupee adds a second driver, because a cheaper dollar reference lifts the premium even when the USDT price is unchanged.
USDC peaked the same day
The India USDC Premium Index peaked on 8 September too, at 5.44%, which is 0.15 points above USDT. Its low was 2.74% on 12 October, as of the 13 October fix. The USDC index uses only two exchanges, giving each venue greater influence on the fix.
Monthly averages of the USDT fixes show the climb and the October dip: 3.49% in July across 17 fixes, 4.02% in August across 21, 4.36% in September across 22, and 3.44% in October across 9 fixes through the 14th.
Limits of the data
- The archive starts on 9 July 2026, so it cannot say whether earlier periods saw readings above 5.29% on the index basis.
- Thirteen daily fixes from 9 to 27 July were restated upward by about 4 to 21 basis points when the index moved to ECB-derived reference rates. Each change is in the corrections log.
- The 25 August fix was published at 18:45 IST after a host memory incident. The value did not change.
- Fixes built on two or three exchanges are thin. The 3 August reading of 4.84% used two.
- Weekend and holiday readings are indicative and excluded from the series. The index is not a forex rate or an official benchmark.
