Is My Money Safe part 3
Another oft-used figure is the net income of the bank. It is important to distinguish interest income from non-interest income. In an open, sophisticated credit market, the income from interest differentials should be minimal and reflect the risk plus a reasonable component of income to the bank. But in many countries (Japan, Russia) the government subsidizes banks by lending to them money cheaply (through the Central Bank or through bonds). The banks then proceed to lend the cheap funds at exorbitant rates to their customers, thus reaping enormous interest income. In many countries the income from government securities is tax free, which represents another form of subsidy. A high income from interest is a sign of weakness, not of health, here today, gone tomorrow. The preferred indicator should be income from operations (fees, commissions and other charges).
There are a few key ratios to observe. A relevant question is whether the bank is accredited with international banking agencies. These issue regulatory capital requirements and other mandatory ratios. Compliance with these demands is a minimum in the absence of which, the bank should be regarded as positively dangerous.
The return on the bank's equity (ROE) is the net income divided by its average equity. The return on the bank's assets (ROA) is its net income divided by its average assets. The (tier 1 or total) capital divided by the bank's risk weighted assets – a measure of the bank's capital adequacy. Most banks follow the provisions of the Basel Accord as set by the Basel Committee of Bank Supervision (also known as the G10). This could be misleading because the Accord is ill equipped to deal with risks associated with emerging markets, where default rates of 33% and more are the norm. Finally, there is the common stock to total assets ratio. But ratios are not cure-alls. Inasmuch as the quantities that comprise them can be toyed with – they can be subject to manipulation and distortion. It is true that it is better to have high ratios than low ones. High ratios are indicative of a bank's underlying strength, reserves, and provisions and, therefore, of its ability to expand its business. A strong bank can also participate in various programs, offerings and auctions of the Central Bank or of the Ministry of Finance. The larger the share of the bank's earnings that is retained in the bank and not distributed as profits to its shareholders – the better these ratios and the bank's resilience to credit risks.
Still, these ratios should be taken with more than a grain of salt. Not even the bank's profit margin (the ratio of net income to total income) or its asset utilization coefficient (the ratio of income to average assets) should be relied upon. They could be the result of hidden subsidies by the government and management misjudgement or understatement of credit risks.
