RUBBER PRICES BECOMING MORE STABLE. 



NOT s J imich is heard nowadays as formerly of the 

 influence of speculation upon the price of crude 

 rubber, and this is probably due to a reason which in 

 lime may lead to the di.sappearance from the trade of 

 speculation, real or alleged. As is well known, the 

 extent of the "invisible supply" of rubber long has 

 l)roved an inconvenient factor in estimating the crude 

 rubber market situation. It has mattered little how well 

 one might be informed in regard to purchasable stocks, 

 and the rate of production and consumption, so long as 

 no idea could be formed of the amount held in store bj' 

 manufacturers. Hence the most carefully made esti- 

 mates of the probable requirements of the market in 

 any particular period have often been iqiset by an un- 

 expected failure of the trade to buy. 



Time was when manufacturers were compelled to buy 

 rubber ahead of their current needs, if for no other 

 reason, to allow it to become thoroughly dried. When 

 the best practice called for the drying of certain rubbers 

 for a year, every important factory necessarily carried 

 large stores, which not only rendered iinpo.s.sible any 

 accurate estimate of the total ruliber available in the 

 countr}' — therefore rendering the cour.se of prices more 

 uncertain — but it involved the tying up of much capital 

 in raw material. There was, however, the advantage of 

 the manufacturer being able to remain out <■>[ the market, 

 in the event of a sudden sharp advance, until a decline 

 occurred. But gradually the time devoted to drying 

 rubber has been lessened — to a few months, then weeks, 

 and even to 24 hours or less — until many factories now 

 carry very little rubber in store as compared with what 

 was formerly considered essential. 



This change of factory practice brings about the buy- 

 ing of rubber more generally on the " hand to mouth " 

 basis, and is leading to the disappearance, in large 

 part, of the " invisible supply." This is now safer than 

 formerly, because of the improved means of communica- 

 tion which, for example, enable the New York trade to 

 learn by cable how much rubber exists at any moment at 

 Manaos, or Accra, or any other primary market, and 

 practically the date on which it can be delivered here. 

 The matnifacturer no longer feels obliged to keep a large 

 supply on hand because of uncertainty on these points, 

 which once was as necessary as storage for the .slow dry- 

 ing of rubber. 



The new condition, therefore, may be summarized as 

 follows : The amount of available rubber in the world 

 can be ascertained accurately on any date, and the 

 amount due to arrive from the principal original .sources 

 for at least a few weeks ahead can be calculated with 

 some degree of safety. If, therefore, the average manu- 

 facturer can be assumed to hold small stocks, le.ss basis 

 exists thau formerly for speculation pure and simple, and 

 prices must constantly tend to become more stable. 

 These tendencies have been at work for j'ears, and the
