Time magazine reported in its September 28, 1931 edition on the shock of the British default. Their comments were as follows:
"Last Monday, all businessmen were shocked to read in their morning papers that the British pound sterling was no longer based on gold. The Tokyo Stock Exchange had announced that it would not open. Tokyo was followed by Bombay, Calcutta, Johannesburg, London, Berlin, Amsterdam, Copenhagen, Vienna, Oslo, Stockholm, Brussels and Athens. The Paris Bourse opened, but limited all trades to 5% of all holdings and no dealing in foreign exchange. Montreal’s Exchange opened similarly restricted. The New York Stock Exchange remained open, but as in dark November 1929, short selling was forbidden. In the artificial market thus created, stocks gyrated unsteadily, closed higher; bonds closed at lows for the year."
In another article, Time reported:
"In few nations nowadays is there a ‘free and open market.’ The Berlin Bourse closed from July 13 to September 3, opened with shortselling banned, then closed again. In Great Britain all trades were put on a cash basis which practically eliminated shortselling as did restrictions imposed on the French and Athenian Bourses. On the Paris Bourse a seller must deposit 40% margin, also 25% on the amount of the stock sold which makes bear activities a rich man’s privilege. One of the most dramatic events of the present crisis occurred in Amsterdam on September 21 when after a terrific slump in prices, all transactions were cancelled, the Exchange closed in status quo. Montreal and Toronto met the British crisis by banning shortsales and establishing ’minimum prices’ for securities, but both last week were open with no restrictions. The Tokyo Exchange has been closing and opening repeatedly during recent weeks. Tokyo stocks broke badly when the shares owned by interests who operate the Exchange collapsed.*
These efforts were a waste of time, the stock markets continued to fall until mid 1932. Similar efforts during the financial crisis of 2008-2009 did not stop the market from declining. Regulators seem to disregard the fact that the short seller is the only participant who is obligated to buy in a falling market inorder to cover his short position. Markets can decline by the mere virtue of sell orders overwhelming buy orders.
