Secure Direct Messages

Here is a secure way of exchanging instant messages.

XMPP is an (open standard) instant messaging protocol that runs on multiple servers without any central authority. OMEMO is an extension of XMPP that implements the “Signal Protocol” as an open standard. The Signal Protocol (advertized by Ed Snowden around 2015) provides fully end-to-end encrypted instant messages between two or more parties.


  • no central authority such as Twitter, Facebook, WhatsApp involved that has access to all meta-data, can censor content, can lock out participants, or maintain back-door keys
  • fully end-to-end encrypted messages between two or more participants
  • every user can have several client programs (mobile app and desktop program, say), the encryption keys remain on the individual devices, and the protocol keeps messages synchronized between devices even if some devices are off-line some of the time

What you need to do:

  • obtain a mobile app such as Conversations (Android) or ChatSecure (iOS) or a desktop programm such as Gajim or Dino
  • register an XMPP account with a public XMPP server that implements the OMEMO standard – usually you can create new accounts from within the app (see the first reference below for how to find a server).
  • add my temporary account,, as a contact and identify youself through another channel (email, etc.). I’ll then tell you my real XMPP account. Don’t use for your account. Find another server using the first link below.


Hope to see some of you soon.

Central Bank Gold Leasing

The salespeople of the gold investment industry publish a lot of bold claims about central bank activities in the gold market (for example, here) along the lines of “All central banks want to suppress the gold price.“, “The central banks have secretly leased and sold most of their gold.” The present article is an attempt to summarize the facts that we know and to offer a rather different interpretation.

GLD – The Central Bank Of The Bullion Banks

The black curve (left scale) of the following chart shows the London pm gold fixing in U.S. dollars from 1 January 2006 to 30 April 2012. During the light-blue intervals which span about 35% of the entire period, the gold price increased at an annualized rate of 41.1%. During the remaining intervals, the price increased only at an annualized rate of 7.9%. The light-blue intervals are the result of a trading algorithm whose buy signals are indicated by the green dots and whose sell signals by the red dots.

GLD Inventory Strategy from 1 January 2006 to 30 April 2012

In this article, we explain how the signals can be computed from the variations of the inventory of the SPDR Gold Shares exchange traded trust (NYSEArca:GLD). We explain why the inventory adjustments can hardly be caused by price arbitrage between the GLD share price and the loco London spot price alone. We rather claim that bullion banks finance their inventory by lending it or selling it to GLD investors and that bullion banks manage their physical reserves by accessing the physical gold inside GLD.

The fact that a certain type of inventory adjustments has predictive power, supports the idea that large inventory changes are the result of active reserve management. This provides us with a unique window into the flow of physical gold that is usually obscured by the dominance of paper gold trading. A similar, but somewhat less robust result is shown for the iShares Silver Trust (NYSEArca:SLV).

WARNING (April 2013): This article uses the term buy signal in a technical sense. It does not mean that you ought to buy anything without understanding what you are doing. Notably, the rapid price increases after the buy signals have been absent since the fourth quarter 2012. Now you might dismiss the trading algorithm as a statistical fluctuation. Alternatively, you can wonder whether something might have changed.

Beware Of The Muppets In The Oil Market

The following chart shows the West Texas Intermediate (WTI) crude oil spot price in US$ (source: US Energy Information Administration).

West Texas Intermediate (WTI) from June 2002 to April 2012

Obviously, there was a speculative bubble from early 2007 to mid 2008 which then collapsed during the second half of 2008. In a series of articles, Chris Cook claims that the crude oil price has been in another bubble since the end of 2009 and that this bubble is just beginning to pop. The present article is an attempt at understanding the mechanics underlying Chris Cook’s ideas.

How Credit Suppresses the Gold Price (with Alice and Bob)

Alternative title: How Credit Creates Inflation
Alternative title: How Gresham’s Law Destroys the Gold Standard

Our small closed economy has five main protagonists, Alice the Automobile Saleswoman, Bob the Banker, Charlie the Capitalist, Dave the Debtor, and Steve the Saver. This small economy is on a gold coin standard, i.e. gold coins circulate as cash. In order to see how the real price of gold (measured in Ferrari sports cars) depends on the creation of credit, we consider the following scenarios.

  • A cash based economy without any lending and without any banks.
  • An economy with banks, but without lending.
  • An economy with banks and with fractional reserve lending.
  • An economy without banks, but with private-to-private lending.
  • An economy without banks, but with commercial Real Bills.

Currency Wars: Why The United States Cannot Return To A Gold Standard

The book Currency Wars by James G. Rickards (Penguin, 2011) quickly became a bestseller not only in goldbug circles. One of the main theses presented by Rickards is that the United States ought to return to a Gold Standard.

Have you ever wondered whether this would be possible? The answer is No. But why not? The reason we give might strike you as rather unexpected, but it leads you right into the question of what will be the future international monetary system. The answer is that it is the existence of the Euro that prevents the United States from returning to a gold standard.

The Euro zone is set up in such a way that it values gold at its free market price. Since the Euro zone is a major global trade hub, they are in fact in a strong position to block any attempt by the United States at returning to a gold standard. They can rather force the US to value gold at its free market price, too. Any attempt at linking the US dollar to a fixed weight of gold is futile in the long run because this would eventually lead to an under-valuation of gold in US$ and thereby irreversibly drain gold reserves from the United States. In the present article, we explain these ideas in greater detail.
