Topics in Financial Markets

This second in a series of articles on topical financial issues offers a few alternative views on two topical questions: over-subscription in IPOs and financial market turnover.

Over-subscription in Initial Public Offerings (IPOs)

Whenever there is an IPO of shares, the focus of attention is invariably on how many times it is over-subscribed. Indeed, the common measurement of success is the degree of over-subscription. Everybody seems to be happy when an IPO is a thousand times over-subscribed, including -- interestingly -- the issuer, who presumably could have priced the IPO shares at a higher level and raised more money. When demand exceeds supply by thousands of times, it is a clear indication that the price, determined by whoever (the issuer, the underwriters or the investment bankers) instead of by the market, is wrong. By the same argument, if an IPO is neither over- nor under-subscribed, that indicates that the shares have been priced at the right level -- one that clears supply and demand. But this is not the sentiment in the primary stock market. The issuer is urged to take a long-term view, in that a heavily over-subscribed IPO sets a good tone for the shares in its debut, and that it will have a high degree of acceptability, and that this assures the success of future additional issues. This is a valid argument but it is very much a matter of degree. And often one has a feeling that the intermediaries, particularly the underwriters, are protecting their interests at the expense of those of the issuer. Regrettably, the issuer is not often in a strong bargaining position against the underwriters. Furthermore, where there are arrangements for share options for the management of the companies newly listed, the personal interests of those involved in taking a decision on pricing invariably come in. So, the successful investors are happy with the large capital gain immediately after listing, the underwriters are happy about the lucrative business that does not involve much risk, the bankers are happy in providing the billions for financing the over-subscription, and the issuer is also happy - well, at least those with share options. But with an IPO priced at the right level, more savings could have been channelled into investments and the public interest of effective financial intermediation could have been better served.

Financial Market Turnover

There seems to be an unchallenged view that the higher the turnover in a financial market the better. High transaction volume denotes high liquidity and great market depth and therefore ease of making transactions. It boosts confidence in the financial market in question and is beneficial to all market players. This is true, and I would say to a large extent. It is, however, necessary to understand where that turnover comes from before taking a definitive view. Take the foreign exchange market as an example. The daily turnover is enormous and the livelihood of many market participants depends on keeping the rate of turnover, earning from the buy-sell spread, charging brokerage fees, or even making short-term bets in that market. But the "real" demand for foreign exchange, for the purpose of making international transactions in both the current and capital accounts, is only a very small fraction of the turnover. A typical estimate of the proportion of such real demand to total turnover is a mere five per cent in a market for a currency with no exchange controls. The other 95 per cent represent turnover generated by those making a market, betting, speculating or taking a strategic position, as it is usually called. The behaviour of this 95 per cent obviously influences the exchange rate a lot more than the five per cent of real demand. But in the economic textbooks we learn that movements in the exchange rate reflect any imbalance in the overall balance of international payments. How true! Even assuming that those responsible for the 95 per cent turnover maintain a square position in the currency, the market dynamics in the short term will probably influence the exchange rate to such an extent that can hardly be justified by the balance of payments position and the other economic fundamentals. They may indeed have serious implications for financial stability.
