World famous economist and former Fed Reserve chairman Dr. Alan Greenspan appeared to be carrying his very own Bermuda Triangle when came to the Island on Monday.

For he was made invisible - at least to the media - when he visited Bermuda.

An odd media-block preventing journalists from reporting his words, or even taking his photograph, was enforced for contractual reasons when the distinguished 81-year-old appeared as a keynote speaker at the 14th Annual MARHedge Global Hedge Fund Summit at the Fairmont Southampton.

Another day, another venue. Yesterday, one day after his Bermuda engagement, Dr. Greenspan was openly covered and photographed at a different financial conference that took place in Boston.

Why the difference? The Bermuda event organisers MARHedge were adamant Dr. Greenspan remained out of bounds to all media because he had asked in his contract for no media or photographs.

The Royal Gazette attempted to probe the reasoning for the media-block beforehand.

MARHedge: "Dr. Greenspan has a strict 'no press' rule."

Royal Gazette: "Can we cover the rest of the conference?"

MARHedge: "As long as you agree not to cover Dr. Greenspan at all."

Royal Gazette: "Any chance of an interview outside his private address, or a picture of him promoting the conference?"

MARHedge: "Absolutely not. The deal is that you may not cover Dr. Greenspan at all. Our contract with him is very specific and it states no press, no photographs, no interviews."

Hundreds of delegates filled the Mid-Ocean ampitheatre to hear Dr. Greenspan "in conversation" covering global financial trends.

However, despite the media-ban a report of his thoughts did hit the international news through the Reuters agency hours later, and was published in the International Herald Tribune. That report is reprinted in the business section under the headline Greenspan in Bermuda: Demand for subprime loan securities down .

• There was no media-block when the former Fed chief spoke yesterday at the 91st LIMRA International meeting in Boston. A report on his thoughts at this event, regarding the US dollar, can be found on page 26.
