Global developments influence the Norwegian financial sector through several channels, via both the real economy and financial markets. Developments in the global economy have an impact on growth, the krone exchange rate and interest rates in Norway. This in turn has an influence on Norwegian enterprises and households, and thereby banks’ lending portfolios. Norwegian securities markets are influenced by developments in international securities markets. Banks are influenced by developments in securities markets through changes in income derived from trading on their own behalf or on behalf of customers. Developments in securities markets and in the international banking industry also affect Norwegian banks’ funding costs.

1.1 The global picture

This summer and autumn, international financial markets have been characterised by increased confidence in an economic upswing. Since the trough was reached in March 2003, equity prices have climbed some 25-35% in the largest markets (see Chart 1.1). The increase in bond yields in recent months (see Chart 1.2) reflects confidence in higher growth, but the immediate effect of the fall in prices is a loss of wealth for bond owners. Macroeconomic indicators in a number of countries show a more positive trend than has been the case for a long time, and corporate results have generally improved. Both sovereign states and individual enterprises are therefore considered to be less risky borrowers now than was the case only a short time ago. This positive trend, however, is vulnerable to a swift correction of financial imbalances. There is uncertainty associated with a sharp rise in debt and house prices in many countries and to movements in bond prices. The greatest uncertainty, however, is associated with the large current account deficit in the US and possible consequences for global economic developments and the financial system if the value of the dollar should abruptly depreciate further.

1.2 Continued large financial imbalances in the US

The US is expected to record a current account deficit equivalent to about 5% of GDP this year. With the exception of three quarters in 1991-1992, the US has had a continuous deficit over the past 21 years. In 2002, the country had a net foreign debt corresponding to 25% of GDP.

Asian countries’ purchases of US securities are now to an increasing extent financing the US current account deficit (see Chart 1.3). While until recently the current account deficit was due to low private saving, it is now a rapidly rising budget deficit that is the main factor. Foreign investors are now primarily buying government securities, while earlier they bought private securities. It is particularly central banks in countries with a large trade surplus and, in part, high capital inflows that are building up large foreign exchange reserves through interventions. The purchases are being made either to counter an appreciation of a floating currency or as a result of a fixed exchange rate regime. China, Taiwan, Japan, South Korea and India increased their foreign exchange reserves by a total of USD 444bn between January 2002 and end-September this year. Most of the reserves are denominated in dollars.

Chart 1.3

The US dollar has depreciated (see Chart 1.4), which is contributing to reducing the US current account deficit. If purchases of US government securities decline, it will be more difficult to finance the budget deficit, possibly resulting in a rise in long-term interest rates in the US. In recent years, economic growth in the US has been sustained by private consumption, fuelled by rising house prices, low interest rates and tax cuts. As a result of the fall in long-term interest rates, households have undertaken extensive refinancing of their home mortgages and, at the same time, increased the loan-to-asset value ratio (see Chart 1.5). Gross housing wealth is accounting for a steadily higher share of total household wealth. Following a long period of high debt growth and low saving, household consumption in the US is not very robust to a fall in the housing market or an increase in interest rates.

1.3 International banking industry

Improved results for banks in Europe and the US

For several years, subdued economic activity and large losses on loans and other claims on the telecom sector have contributed to low profitability and substantial loan loss provisions in large parts of the European banking industry. In mid-2003, however, many banks’ financial statements showed improved results and a decline in loan loss provisions. This also applies to a number of banks in the Nordic countries. These have the largest potential spillover effect on the Norwegian financial industry through subsidiaries, branches and other activities focused on Norway. The European banking industry is vulnerable to weaker-than-projected cyclical developments. This autumn, the risk premium on bonds issued by financial institutions in the euro area has increased relative to the corporate sector as a whole (see Chart 1.6).

Chart 1.6

Banks in the US have shown substantially improved results. Pre-tax profits increased by 11% in the second quarter of 2003 compared with the same period one year earlier, and the default rate has fallen markedly (see Chart 1.7). US banks have fared well through the period of falling stock markets, and have recorded considerable earnings on their securities positions over the past year.

New measures to strengthen Japanese banks

In general, Japanese banks have low equity capital and large portfolios of non-performing loans, even though the latter has declined somewhat (see Table 1.1). Deflation has increased enterprises’ debt burden in real terms, but low interest rates mean that a number of enterprises can service their loans despite weak earnings. As a result of bank’s exposed positions, their capacity to extend new loans to the large number of small and medium-sized enterprises is limited.

Table 1.1

The authorities are now supporting measures whereby banks’ lending portfolios are being sold to companies that issue securities based on these lending portfolios. The objective is both to promote a better securities market for financing enterprises and to strengthen banks’ balance sheets. The central bank has announced that it will be able to purchase such securities for up to JPY 1000bn (about NOK 63bn). Since autumn 2002, the central bank has also made substantial equity purchases from banks in order to reduce their exposure to the stock market.

More than half of the core capital in the largest banks consists of deferred tax assets, which cannot function as a buffer against losses in the short term. The IMF has estimated that a 20% drop in the stock market or a 3 percentage point higher write-off of loan losses will result in the loss of all equity capital, except tax credits, in the largest banks. In May 2003, the Japanese government injected new capital into one of the country’s largest banks after the rules on the recording of tax credits were tightened. Private ownership was maintained.

Global house prices and credit growth

The housing market is of considerable importance to financial stability. Dwellings normally account for the largest wealth component for households. A rise in house prices may lead to an increase in households’ home mortgages, both because it is more expensive to buy a dwelling and because they borrow more in connection with refinancing. In many countries banks are the most important source of financing for house purchases. Mortgages are usually provided with the dwelling serving as collateral. Banks are therefore vulnerable to a decline in house prices. Banks also have exposures to the construction sector. A fall in house prices may result in lower construction activity, excess capacity and weaker results in the industry. This will increase banks’ credit risk.

For a long time, statistics on house prices have not been readily available or very comparable. As a result of an increased focus on financial stability in recent years, a number of countries have initiated projects in order to compile and publish statistics on the housing market.1

Chart 1 shows changes in indexed nominal house prices in selected countries since 1995. In the UK and Norway, house prices have risen sharply. In the last three years, however, the rate of increase has been far stronger in the UK than in Norway. The US index is somewhat flatter, but has nevertheless risen by more than 50% since 1995. Germany and Japan have experienced the opposite, with stable or falling house prices throughout the period.

Chart 1

Countries that record a sharp rise in house prices also have high growth in total domestic credit (see Chart 2). Among the countries examined here, only Germany and Japan have recorded low or negative credit growth. The positive relationship between the rise in house prices and credit growth also applies to earlier observation dates. Norway is an example of a country where credit growth remains high even after house prices level off. In the period from 2000 to 2003, the 12-month rise in house prices fell from 17% to about 2%, while the 12-month growth in credit remained more stable at about 9-12%. One reason for continued high credit growth is the preceding period of sharp increases in house prices, which often results in an increase in the loan-to-asset value ratio in connection with a change in ownership. In addition, housing turnover has remained buoyant. This is discussed further in section 2.2.

1.4 International securities markets

Rally in stock markets

Equity prices have risen substantially since this spring in the US, Europe and Japan (see Chart 1.1), although they have fallen again recently in Japan. The broad-based rise primarily reflects an improved economic outlook, partly as a result of record-low interest rates in many countries. Very low interest rates have also resulted in lower returns on alternative investments. The gains in stock markets improve financial institutions’ balance sheets and enterprises’ access to new funding and potential growth. Following a lengthy decline in equity prices and improved corporate earnings, the valuation of equities is now more normal. In the US market, the P/E ratio is back to the level prevailing in 1997 (see Chart 1.8).

Chart 1.8

Increased investor confidence in US enterprises?

Since spring 2003, investors have required a steadily lower excess return in relation to safe government bonds in order to buy bonds issued by US enterprises (see Chart 1.9). There may be several explanations for this. First, investors’ risk aversion may be lower. Second, investors may adapt to new information more quickly than credit rating agencies. When there are more optimistic expectations concerning economic developments, the market may for a period consider some borrowers to be less risky than implied by their credit rating. As a result, the yield spread for a given credit rating may narrow during an economic upturn, even though investors’ risk aversion and borrowers’ credit ratings are unchanged. Third, it is conceivable that in a market with very low interest rates, investors do not behave entirely rationally and purchase more risky bonds in order to achieve a higher return.

Chart 1.9

Improved conditions for emerging economies

Both low interest rates in industrial countries and lower risk aversion may have led to a lower risk premium required by investors to invest in emerging economies (see Chart 1.10). Several countries have succeeded in issuing bonds containing clauses that make it easier to achieve a coordination of creditors in the event of any debt restructuring. Issuers have not had to pay extra premiums to have these clauses included.

Chart 1.10

Since the moratorium on government debt in 1998, Russia has experienced a very swift economic upturn. Equity prices for Russian companies have almost doubled since the beginning of the year. In October, the country’s debt was upgraded to investment grade. Since many investors in government securities apply this credit rating as a minimum requirement in order to invest, Russia may see a further improvement in its funding possibilities in the period ahead. At the end of October, the head of Russia’s largest oil company was arrested, charged with corruption and tax evasion. The Russian authorities seized 44% of the shares in the company. The event contributed to an increase in the risk premium on Russian debt.

1.5 Securities markets in Norway

Rise in prices and lower credit risk premiums

Historically low interest rates and a rally in international stock markets have contributed to a sharp rise in prices in the Norwegian stock market since the previous report (see Chart 1.11). Over the past six months, the Norwegian stock market has risen considerably more than international stock markets. In earlier periods of substantial price movements the effects have also been greater in the Norwegian market than in other countries.

Chart 1.11

The bank index showed weaker developments than other sub-indices this summer, but has since risen rapidly. The rise partly reflects investors’ favourable response to third-quarter results in many banks as well as the Norwegian Competition Authority’s decision to approve the merger between DnB and Gjensidige NOR on certain conditions. Other market indicators also show that investors consider banks’ financial position to be favourable (see box on p. 16 for a discussion of the indicators). The risk premium on bonds issued by Norwegian banks has been declining in recent months (see Chart 1.12). Developments in the probability of default based on market data for Norwegian commercial and savings banks show the same picture (see Chart 1.13). The probability of default among the weakest banks has been falling over the past two years, while the median bank has exhibited stable developments. The volatility of Norwegian bank shares has been sharply reduced since the spring (see Chart 1.14).

High turnover in several markets

In the first three quarters of 2003, turnover in both equity and bond markets was higher than in the same period last year. The volume of bonds traded on the Oslo Stock Exchange was 27% above the level in the same period in 2002. In particular, turnover has been high in the government bond market. High demand for long-term fixed income instruments as a result of the fall in short-term interest rates through the spring and summer contributed to this.

The rise in prices and higher turnover in the stock market have resulted in increased activity in the derivatives market. Permission for insurance companies and mutual funds to use derivatives has probably also been a factor. Turnover in exchange-traded option contracts has been increasing since May 2003, and in September this year the number of open positions in the option market was at its highest level since March 2001.

Fluctuations in the foreign exchange market in recent years have resulted in higher demand from enterprises for long-term currency hedging products, such as options, futures and currency swaps. Prices for such derivatives have fallen somewhat, but there are wide price differences between the various products and between customers.

Fall in issuance of private bonds

The issuance of private bonds has fallen in the first three quarters of 2003 compared with the same period last year. Both commercial banks and private non-financial enterprises have reduced their issuance of bonds in the Norwegian market. Savings banks, however, have increased their borrowing by 38% in the period, and so far this year have been the largest issuer in the Norwegian market. Savings banks and commercial banks have issued two thirds and half, respectively, of their bond debt in Norway. Increased issurance of government bonds contributed to a total issue volume in the Norwegian bond market that was 14% higher in the first three quarters of 2003 than in the same period last year.

In the stock market, the issue volume was lower in 2003 than in 2002 up to the end of the third quarter, but picked up in October. The conversion of debt to equity in companies with debt problems accounts for a considerable portion of the share issues.

Higher new purchases in mutual funds

Net new purchases of units in Norwegian-registered mutual funds were relatively high in September, at NOK 1.8bn, after showing negative figures in July and August. Equity funds pushed down this figure despite low money market rates and a rising stock market. During the third quarter, there has nevertheless been a pronounced increase in net new purchases in equity funds.

Market-based indicators of banks’ financial position

Securities markets can provide useful and current information on banks’ financial position. Indicators based on market data reflect market participants’ expectations concerning future developments, and they may be updated often. Market indicators of banks’ financial position may be based on market data both for banks directly and for enterprises in banks’ credit portfolios.

The spread between the yield on bonds issued by banks and the yield on government bonds (risk-free interest rate) is an indicator of banks’ financial position. When investors' view is that a bank’s financial position has deteriorated, they will require increased compensation for buying the bond, and the yield spread widens. The downside risk will probably be better reflected in the bond market than in other markets as bond owners do not have access to potential gains as a result of increased risk-taking in banks. The yield spread may, however, contain a liquidity premium. Changes in the yield spread may therefore reflect changes in liquidity instead of a change in the assessment of the bank’s financial position. It is difficult to quantify this liquidity premium.

New information is often incorporated more swiftly in the equity market than in the bond market. This is because turnover and the turnover rate are normally higher in the equity market. Data on banks’ share prices have for a long time been used as an indicator of risk in banks. One problem associated with this indicator is that the share price should reflect the discounted value of all future earnings, so that the share price can vary considerably even if the credit risk does not change. An alternative indicator is the return on portfolios of bank shares. A study of Swedish bank shares prior to, during and after the banking crisis in Sweden in 1990-1992, found a significant difference in the cumulative return between shares in banks that received government support during the banking crisis and banks that managed without government support.1 The difference was significant up to three years prior to the crisis. Similar results have been found in studies conducted, for example, in the US.

Volatility in the return on bank shares may provide valuable information on risk in banks. Since shares in a bank may be looked upon as claims on the bank’s assets, volatility in the equity return may provide information on investors’ assessment of the risk associated with the bank’s assets. Increased risk on the asset side will result in increased volatility in the equity return. Studies of the banking crises in the Nordic countries show that up to ten years prior to the crisis one observed significantly higher volatility in the equity return in crisis-hit banks compared with banks that avoided a crisis.

Implied volatility from equity options can also be used as a risk indicator. Implied volatility is the market’s estimate for the volatility of a share in the period up to the option’s expiry date. Increased uncertainty about the share’s price movement will be reflected in higher implied volatility. Options with different exercise prices but the same maturity can provide further information about this uncertainty. Different implied volatilities for different exercise prices can provide a picture of the direction of the uncertainty concerning the share’s price movements.2

Option theory can provide information on the risk in banks in other ways as well. The share capital of a bank may be looked upon as a call option on the bank’s assets. The option provides payment to shareholders if the market value of the bank’s assets is higher than the bank’s liabilities on the option’s expiry date.3 Since one can observe the value of liabilities, as well as the market value and volatility of the share capital, it is possible with the help of option pricing models to derive the assets’ market value and volatility. These variables are an indication of expected changes in the value of assets and the uncertainty associated with this change in value. Against this background, it is possible to estimate the probability that the bank will default on its obligations.4
