What is gold to silver ratio trading?

Topics [ gold investing silver investing ]

The gold to silver price ratio is a measure of how many ounces of silver are required to buy an ounce of gold.

For a long period of human history both were monetary metals and the ratio was generally fixed. Today, however, the ratio floats – reflecting market forces that determine gold and silver prices on a daily basis.

The average gold to silver ratio during the 20th century was 47 to 1. Over the past 20 years the average has been nearer to 60 to 1.


For some hard assets enthusiasts, the gold to silver ratio is the basis of their precious metal trading strategy. In particular, they are interested in times when the ratio fluctuates widely from the prevailing norm.

The theory is that a high ratio signals it could be time to favour silver – which appears relatively cheap by historical standards.

Conversely, a low ratio may mean it could be a good time to purchase gold.

Currently the gold to silver ratio is spiking at 86 to 1, meaning it requires 86oz of silver to buy 1oz of gold. At well above its 10-year average of around 66 to 1, this abnormally high level could be interpreted as a powerful trading signal.

Of course, nothing is certain and given the nigh impossible task of picking extreme relative valuations between the metals, ratio trading presents many pitfalls for the unwary. Nevertheless, it is useful to be aware of the ratio when researching the many factors likely to affect precious metal prices.

2017 Silver Kangaroo set for success after sales of 2016 coin leap past 11 million

Topics [ Australian Kangaroo silver investing silver bullion silver coins buy silver coins ]

The Perth Mint is pleased to announce that the 2017 Australian Kangaroo 1oz Silver Bullion Coin is available earlier than originally scheduled.

Released today, the new issue follows an exceptional debut in 2016 for Australia’s first 99.99% (four nines) pure silver bullion coin. With sales in excess of 11 million, factors behind its success included an iconic design, micro-engraved security feature, and extremely competitive pricing.


Now an established annual release from Australia’s official bullion coin program, the Silver Kangaroo is an ideal proposition for anyone seeking the safety of precious metals in a volatile economic landscape. Contributing to investors’ confidence in the coin is the trusted reputation of the 117-year old Perth Mint.

One of the world’s leading integrated refining and minting enterprises, the Mint operates Australia’s only gold and silver refinery accredited by the London Bullion Market Association. As well as producing benchmark good delivery bars and a wide range of retail investment bars, it has made almost 51 million bullion and numismatic coins over the past 30 years, which are admired for their weight, purity and designs.

The 2017 Australian Silver Kangaroo features a ‘red kangaroo’ based on the historical design first witnessed on Australian bullion coins in 1989. Like its immediate predecessor, the new coin benefits from a tiny letter ‘A’ in the reverse inscription as verification of its authenticity.

250-coin mini-monster box

Offered individually, the highly affordable Silver Kangaroo can also be acquired in tubes of 25 coins or in mini-monster boxes containing 250 coins - allowing buyers to take advantage of attractive volume discounts. The mini-monster box is perfect for secure storage in third-party safe deposit boxes.


Available from the Mint’s Bullion Trading Desk; via the BullionLine on 1300 201 112 (Australia) or +61 8 9421 7218 (International); and at perthmintbullion.com, the 2017 Australian Kangaroo 1oz Silver Bullion Coin can also be purchased through leading coin dealers.

NEW RELEASE Australian Funnel-Web Spider Silver Bullion Coin

Topics [ silver investing silver bullion coins buy silver bullion online ]


Released today, the latest silver bullion coin from The Perth Mint featuring dangerous Australian animals portrays a funnel-web spider.


At least 40 different species of funnel-web spiders live in south-eastern Australia. The most notorious is the Sydney Funnel-Web, whose venom is highly toxic to humans.

Funnel webs are medium to large spiders with a body reaching up to 5 cm in length. For anyone with arachnophobia they are one of the most macabre in appearance, ranging from black to brown with a glossy, hairless carapace covering the front part of the body.

The aggressive Sydney Funnel Web is regarded as one of Australia’s top-ten deadliest creatures. Its fangs are said to be longer than a brown snake’s and so powerful they can pierce toenails!

Not surprisingly, a bite is agonizing. The male’s venom is about five-times more painful than the female’s, making it the most likely candidate for at least 13 human deaths prior to the introduction of antivenom in 1981.

2015 Australian Funnel-Web Spider 1oz Silver Bullion Coin

This new bullion release portrays a large funnel-web spider. Struck from 1oz of 99.9% pure silver and issued as Australian legal tender, it has a mintage of 1,000,000 coins worldwide.


The 2015 Australian Funnel-Web Spider comes in protective tubes containing 25 coins, and in monster boxes of 20 tubes containing 500 coins.

Tubes cost $5.00 over metal per coin, with the price decreasing to $3.95 over metal for 500 coins.


The new coins are available from The Perth Mint to retail customers in Australia only. Please visit www.perthmintbullion.com (registration required) or visit/call our bullion desk on 1300 201112.

The coins are available to customers worldwide from leading bullion coin dealers.

China To Support Silver Market In 2015

Topics [ silver investing silver prices silver market ]


If you mention China, most people think of gold. However, China is also a big consumer of silver, net importing between 5% to 10% of global annual supply of 30,000 tonnes. A recent note by David Jollie of Mitsui Global Precious Metals focusing on the Chinese silver market concludes that it will provide support to the silver price in the short to medium term.

While net imports of refined silver into China peaked in 2010 at 3,475 tonnes, David’s analysis of other public and in-house data shows that China’s total silver demand actually peaked at 6,270 tonnes in 2013, with 2014’s figures only declining by 1.9%. For 2015, he expects imports of silver to rise sharply on the back of stable local mine production, low exchange stocks and 7% GDP growth driving positive growth in the solar, automotive and electronics sectors.

In addition, David believes that investor interest in silver that drove the price to its highs in 2011 has mostly been eliminated, based on an intriguing comparative analysis of silver and indium (which share similar mining and end-use market structures).

This means “that there is scope for silver to regain some of its [investor] premium. If gold rallies further, international investors can be expected to send silver higher”. Furthermore, David thinks that commodity financing deals using silver will return, resulting in further demand for silver out of China.

Manufacturer Accreditation Provides Comfort To Investors

Topics [ silver investing gold investment silver bars gold bars bullion bars ]


To trade efficiently, market participants need to agree on standards for the products they deal in. In addition to agreeing where the product they will trade will be located (eg COMEX gold must be in a warehouse in New York) and in what form (eg bars weighing 100oz), market participants need to agree on which manufacturers they will accept product from. This is the purpose of accreditation.

In the precious metals markets it is the refiners that are accredited, as refiners are the first point of supply into the market of purified and standardised gold and silver. Accreditation occurs on a market by market basis as well as by metal. So it is possible that a refiner may be accredited for gold but not silver, or in one market but not another. Most of the major refiners are accredited across markets. For example, The Perth Mint is accredited as a refiner, weight master and assayer with the:

London Bullion Market Association (LBMA)
New York Commodity Exchange (COMEX/CME)
Dubai Multi Commodities Centre (DMCC)
Tokyo Commodity Exchange (TOCOM)

The most widely recognised and respected accreditation is that granted by the LBMA, which is also licenced by the CME as part of its own accreditation procedures for COMEX. This status is not just based on the requirements for listing, which include an established track record and minimum annual refining volumes and tangible net worth, but also the rigorous scrutiny of an organisation's standards and procedures and the successful completion of searching practical testing before being accepted for accreditation.

In addition, LBMA accredited refiners are subject to a Proactive Monitoring regime where they have to demonstrate the are maintaining LBMA refining and assaying standards on an ongoing basis.

Market participants can therefore be assured of the stated weight, purity and integrity of the products produced by accredited refiners. The end result is that traders will accept bars from any accredited refiner without question in settlement of their trades, which simplifies the process for both buyer and seller.

The LBMA's list of accredited refiners can be found here.

Review of small investment cast bars made by the LBMA-accredited Perth Mint.

Finally, it is important to distinguish between accreditation of refiners from accreditation of product. Each market has different rules as to what form is acceptable for settlement. For example, while The Perth Mint is accredited with both the London and COMEX markets, only its 400oz Good Delivery Bar is accepted in the London market whereas only three Perth Mint gold kilo bars (or a 100oz bar) would be acceptable in settlement of a COMEX futures contract. Perth Mint coins would not be acceptable in either of those markets as they are professional wholesale markets which do not deal in small sized products.

While small sized bars and coins are not themselves accredited, investors do often take comfort that a manufacturer of bars and coins is accredited because it means that the accreditation weight, purity and integrity standards will apply across the organisation and thus to all of their products.
