He used his chairman's statement in the trust's 2014 annual report to outline his concerns, saying that on top of a "difficult economic background" investors face "a geopolitical situation perhaps as dangerous as any we have faced since World War II".
He said this was the result of "chaos and extremism in the Middle East, Russian aggression and expansion, and a weakened Europe threatened by horrendous unemployment, in no small measure caused by a failure to tackle structural reforms in many of the countries which form part of the European Union".
Comment: It is not a stretch to say that all the above conditions of our current reality exist primarily because of the United States and their empirical machinations to have total hegemonic control over the world.
This was a much gloomier assessment of the world than the picture painted in his statement a year ago. Then, he listed the major dangers as the slowdown in China's growth and a possible over-valuation of shares.
The trust was established in the Sixties with the aim of overseeing much of Jacob Rothschild's personal wealth. He and his daughter Hannah, who is also on the trust's board, together own shares worth approximately £160m.
RIT is popular among private investors thanks to its excellent track record and its conservative approach to conserving capital (see graph, below or click here for more charts).
The "preservation of shareholders' capital remains our highest priority, taking precedence over tactical manoeuvres based on short term returns," Lord Rothschild has stressed.
Its 2014 results, just published, show assets up almost 10pc in the year. Increasing demand for its shares meant the share price rose even more significantly, up 13.3pc over the year.
Dividends for 2015, to be paid in April and October will be up 2pc.
The trust was listed on London's Stock Exchange in 1988 since when it has delivered an average annual return of 12pc.
It invests in a range of assest including shares in quoted businesses, other funds and property. It owns the £33m leasehold of Spencer House, for example, an 18th century mansion in central London, which is let for functions.
this seems to follow the pattern recently of 'the popular insiders' coming out in public to give the 'doom and gloom' report. I take it to mean that this is the sign for the collapse of this project of theirs? The timing is interesting given all the insider selling at the same time their companies are buying up those same shares... gives them time to position themselves for the collapse. And recently HSBC preps their clients to get out their gold deposits as they are getting out of that business. Seems almost all of the cards are ready to knock down.... and April is approaching.
