This is a thematic page. It carries no Market Snapshot ratings. Measures are as recorded on the sector pages at their snapshot dates; tariff rates in particular change quickly and the sector page governs.
IFour instruments
Four kinds of state measure appear across the market pages, and they do different things to a holder. A sanction bars an origin from a market altogether: Russian diamonds from the G7, Myanmar jade from sanctioning jurisdictions, Iranian saffron from the banking system, Cuban cigars from the United States. A tariff taxes an origin at the border and moves the price gap between origins: US duties on polished diamonds by country of cutting, on Brazilian coffee, Tunisian olive oil, Japanese tea and, for fifteen months, Scotch. An export control is applied by the producing state: Chinese licences on seven rare-earth elements, Italy's pre-emption of an Old Master, Somaliland's licensing of resin, Saudi limits on farmland. A species listing under CITES conditions every cross-border move of a living or once-living thing: sturgeon, falcons, agarwood, Boswellia since 2025, Brazilian rosewood on a pre-1969 guitar.
What they share is that they act on origin, and origin is the claim the Provenance page found hardest to prove. A sanction on Russian rough is only as good as the ability to tell Russian rough from Botswanan after both have passed through Surat; a tariff by country of cutting requires a customs officer to know where a stone was cut. Every instrument on this page therefore creates a demand for the same thing: a document, a ledger or a laboratory that can say where a thing came from. The G7 diamond regime is the clearest case, and Section III takes it in detail.
The second thing they share is that they move trade rather than stop it. Saffron passes through Dubai and La Mancha labels; jade has "no route at all" into sanctioning jurisdictions and a full one in Hong Kong; rare earths outside China trade at a dealer premium that is the price of the licence. Section V follows where the trade goes.
IIThe register: live measures
Every market page that records a sanction, tariff, export control or species listing in force or recently changed, as at its snapshot date. Markets not listed record no such measure; they are named at the foot of the table.
| Market | Instrument | Measure, as the sector page records it | What it does to a holder |
|---|---|---|---|
| Rough Diamonds | Sanction; certification | G7 ban on Russian-origin diamonds, phased from 1 Jan 2024; Kimberley Process certificate on every export 1 2 | Origin must be documented at 0.5 ct and above; Antwerp made the verification node; Alrosa's goods excluded from G7 markets |
| Polished Diamonds | Tariff; sanction | Since 24 Jul 2026 the US taxes natural polished by country of cutting (India 10%); Russian-origin barred regardless of rate 20 | Widens the dealer-bid gap for stones cut abroad; a stone's cutting country becomes a priced attribute |
| Lab-Grown Diamonds | Sanction | G7 ban extended to Russian synthetic diamonds and diamond-set jewellery and watches at 0.5 ct from 1 Sep 2024 3 | Growers' origin now a compliance item; Indian and Chinese output unaffected |
| Jade | Sanction | The sole legal source is a sanctioned Myanmar military enterprise; import and resale of recent material legally uncertain in sanctioning jurisdictions 21 | No Western route for recent material; the market is Hong Kong and Guangzhou |
| Coloured Gemstones | Tariff | 2025 decline in US imports read as tariff-related front-loading into 2022–24 22 | Timing of imports, not the route; Burmese origin carries its own US history of restriction |
| Saffron | Sanction (banking) | Iranian supply is sanctioned at the banking layer 23 | Trade re-routes through Dubai and Spanish labels; re-exporters capture the label premium the grower never sees |
| Cigars | Sanction (embargo) | US import rules restrict who can buy and sell Cuban product 24 | No route for US sellers of Cuban cigars; the market is Europe, Hong Kong and the Gulf |
| Uranium | Sanction; export control | US ban on Russian enriched uranium imports from 2028, with waivers until then; material subject to export control 25 | Enrichment, not mining, is the choke point; the trust holds material in licensed custody |
| Rare Earths | Export control; sanction | Chinese export licensing on seven elements since April 2025; US defence ban on Chinese-origin rare earths from 1 Jan 2027; Malaysia raw-ore export ban 26 | Whether material can move at all; the ex-China dealer premium is the price of the licence |
| Copper | Tariff (threatened) | US refined-cathode tariff decision lapsed 28 Sep 2026 with no announcement; COMEX premium collapsed from over $3,000/t to about $310 27 | Metal pulled into US warehouses on the threat, then stranded; location became a price |
| Platinum group metals | Tariff (feared) | Metal flowed into CME-approved US warehouses on tariff fears in 2025, then reversed 28 | The swing factor in the published balances for a year |
| Coffee | Tariff | 50% US tariff on Brazilian goods; coffee exempted on 20 Nov 2025 29 | Four months of re-routing and a correction on the sector page |
| Olive Oil | Tariff | 25% US country tariff on Tunisian oil introduced in 2025; US tariffs on EU oil 30 | Shifts the origin mix bottlers buy for the US market |
| Tea | Tariff | 15% US tariff on Japanese imports adds to café costs for matcha 31 | Landed cost in the largest matcha export market |
| Scotch Whisky | Tariff | 10% US levy from April 2025 (25% threatened on single malts); tariff-free access restored 24 Jul 2026 32 | Fifteen months of a priced origin in the largest export market; 2025 exports flat in value, down in volume |
| Watches | Tariff | Patek Philippe rolled back some US prices by up to c. 8% after tariff and currency moves 33 | Retail price by market, and so the grey-market arbitrage |
| Art | Tariff; export control | Cross-border shipping and tariff regimes tracked as an indicator; national export controls on cultural property 34 | Where a work can be consigned and at what landed cost |
| Old Masters | Export control; restitution | Italy's pre-emption of the Antonello; the UK deferral system; restitution claims and Nazi-era provenance gaps 35 | Can delay, block or reprice a sale after the hammer |
| Coins | Export control (cultural property) | Ancients subject to cultural-property claims, US State Department MoUs and import restrictions 36 | Title risk and seizure on raw and ancient coins; none on slabbed modern coins |
| Fossils & Meteorites | Export control | Legal export documentation from the country of excavation is the title 37 | Specimens from countries that bar export cannot be sold openly |
| Caviar | Species listing | CITES labelling on every tin; the only luxury food with a mandatory international chain-of-custody label 38 | Paperwork on every sale; the page records evidence the label is routinely defeated |
| Falcons | Species listing | Every transfer needs a CITES permit; closed ring, certificate and passport required; 2026 rules tie racing eligibility to auction purchase 39 | A bird without matching papers cannot travel or be resold; wild-trapped birds are not an asset |
| Oud | Species listing | CITES export permits on every cross-border move; legal provenance for wild material often does not exist 40 | The wild tier, rated High scarcity, is the tier hardest to move legally |
| Frankincense | Species listing; export control | Boswellia listed on CITES Appendix II from 2025; export licensing in Somaliland 41 | Paperwork a private seller cannot easily complete |
| Vintage Guitars & Instruments | Species listing | Brazilian rosewood on CITES Appendix I since 1992 (pre-1969 Martins and Gibsons); tortoiseshell; pre-convention certificates needed for cross-border sale 42 | A 1950s guitar needs a certificate to cross a border; the best material is the most restricted |
| Bluefin Tuna | Quota | International catch quotas (ICCAT, WCPFC, CCSBT); Pacific limits raised 60% for 2025–26 43 | Supply is a treaty decision; a ranching licence transfers with its quota |
| Dates | Ownership restriction | Foreign ownership of Saudi farmland restricted 44 | The farm route is closed to most outside holders |
Twenty-seven rows. The remaining 24 market briefs (Gold, Silver, Oil & Gas, Cocoa, Fine Wine, Champagne, Port, Rare Whisky Casks, Japanese Whisky, Pu-erh Tea, Parmigiano Reggiano, Vanilla, Manuka Honey, Maple Syrup, Truffles, Wagyu, Racehorses, Breeding Stallions, Pearls, Signed Jewellery, Handbags, Stamps, Rare Books, Classic Cars) record no sanction, tariff or listing bearing on the holding at their snapshot dates. Gold and oil carry origin sanctions at the trade level (Russian bars and barrels) that the sector pages treat as not reaching a portfolio holder; cocoa's marketing boards and maple's Federation are domestic administration, covered under Who sets the price.
IIICase: Russian diamonds
The one sanction in the register built on a traceability requirement rather than a border check, and so the test of whether origin can be enforced in a market that mixes its goods.
| Date | Measure | Confidence | Source |
|---|---|---|---|
| 11 Mar 2022 | US bars import of non-industrial diamonds mined in Russia | High | 4 |
| 1 Jan 2024 | G7 and EU ban direct import of diamonds mined, processed or produced in Russia, or transited through it | High | 1 2 |
| 1 Mar 2024 | Ban extended to Russian diamonds processed in third countries, at 1.0 ct and above, closing the "substantial transformation" route through India | High | 2 4 |
| 1 Sep 2024 | Threshold lowered to 0.5 ct; extended to lab-grown diamonds and to jewellery and watches incorporating diamonds; traceability evidence required | High | 3 5 |
| 2024– | Antwerp designated the verification node; a G7 certificate issued for imported natural rough of 0.5 ct and above of non-Russian origin; none for polished | Med | 3 6 |
| May 2026 | GIA agrees a 30% stake in De Beers' Tracr provenance ledger, which has registered more than 5m rough stones | High | 45 |
A statement of origin for every stone above half a carat crossing a G7 border, when about 90% of the world's polished is cut in India from mixed parcels. 4 20 The Kimberley Process certifies that rough is not conflict-financed, not which mine it came from; the sanction needed a second document the trade did not have.
A verification hub in Antwerp, a certificate for compliant rough, and a commercial reason for the industry's provenance ledgers, which the Tokenisation page records had been attempted for a decade without a business case. The sanction supplied one.
Alrosa's goods to buyers outside the G7, Indian cutting into a documented chain, and the question of origin from a marketing claim to a customs requirement. The sector page's Provenance risk line for rough reads "KP certificate, G7 sanctions on Russian origin": the sanction is now part of the provenance. 46
IVCase: the 2025–26 tariff round
Seven of the market pages record a US tariff imposed, threatened, lifted or exempted between April 2025 and July 2026. Read together they show what a tariff does to a scarce asset: it prices location and timing, not the thing.
| Market | Measure | What moved | Source |
|---|---|---|---|
| Scotch Whisky | 10% from Apr 2025; lifted 24 Jul 2026 | 2025 exports flat in value, down in volume; the threatened 25% on single malts never applied | 32 |
| Polished Diamonds | Duty by country of cutting from 24 Jul 2026 (India 10%) | The cutting country became a priced attribute of a stone, on top of its grade | 20 |
| Coffee | 50% on Brazil; coffee exempted 20 Nov 2025 | Four months of re-routing; Brazilian supplies then at risk of missing ICE warehouses before expiry | 29 |
| Copper | Refined-cathode tariff threatened; decision lapsed 28 Sep 2026 | COMEX premium over LME from above $3,000/t to about $310; US warehouses holding about 70% of visible exchange stock | 27 |
| PGMs | Tariff fears, 2025 | Metal into CME-approved US warehouses, then out; the swing factor in a year's balance | 28 |
| Olive Oil | 25% on Tunisia, 2025; duties on EU oil | Origin mix for the US market | 30 |
| Tea, Watches | 15% on Japan; Swiss duties | Landed cost of matcha; Patek Philippe price cuts of up to c. 8% in the US | 31 33 |
For the exchange-traded metals the tariff never had to be imposed to move the market: the threat alone pulled copper and platinum into US warehouses and opened a location premium that then collapsed when the decision lapsed. For the collectibles and consumables the tariff was imposed and either lifted (Scotch, coffee) or absorbed into the price list (watches). In neither case did it change what the asset was; it changed where it was worth holding it. Hyp
VWhere the trade moves to
An origin rule in one jurisdiction creates a hub in another. The sector pages name the hubs.
Iranian saffron passes through Dubai to escape banking sanctions; rough diamonds tender in Dubai alongside Antwerp; the rare-earths page notes free-zone trading and vaulting already used for gold and diamonds. 23 46 26
The only auction depth for jadeite and the route for Myanmar material that the West will not take; record Japanese whisky sales "for a reason"; one of three cities for the top coloured-stone sales. 21 47
Spanish labels on Iranian threads: re-exporters capture the origin premium the grower never sees, and customs values for Spanish saffron run above Afghan. 23
VIThree patterns in the record
Every origin rule creates a paper requirement
G7 certificates, CITES permits, Kimberley certificates, pre-convention certificates for rosewood, export licences for an Old Master: the measure is enforced by a document, and the document becomes part of the asset. A falcon without its papers, a guitar without its certificate and a stone without its origin record are each worth less than the same object with them.
Watch: whether the diamond regime's traceability requirement is extended to polished and to lower thresholds
Trade moves to the nearest jurisdiction that does not ask
Dubai for saffron and rough, Hong Kong for jade and whisky, Spanish labels for Iranian threads. The sanctioned origin does not leave the market; it leaves the sanctioning jurisdiction, and the holder in that jurisdiction loses a route rather than the asset losing a buyer.
Watch: Hong Kong and Dubai auction calendars for categories the West restricts
A tariff prices where a thing is, not what it is
Copper and platinum moved into US warehouses on a threat and were stranded when it lapsed; Scotch paid 10% for fifteen months and then did not; a polished stone's cutting country now carries a duty rate. None of these changed the asset. They changed the value of holding it on one side of a border rather than the other, which is a cost the sector pages' Liquidity lines do not capture and this page does.
Watch: COMEX–LME and US–London premiums as the live price of a tariff threat
VIIIndicators to monitor
- Any lowering of the G7 diamond threshold below 0.5 ct, or extension of G7 certification to polished stones, which the EU FAQ leaves open 5 6.
- Chinese rare-earth export licensing after the current pause and the US defence ban from 1 Jan 2027 26.
- The US refined-copper tariff decision, lapsed in September 2026 without announcement 27.
- Enforcement of the 2025 CITES listing of Boswellia, and whether it reaches resin already in trade 41.
- The US ban on Russian enriched uranium from 2028 and the waivers issued before it 25.
- Any change in US or EU sanctions on Myanmar's gems enterprise, which would reopen or close the Western route for jade.
