In the last 20 years there were two periods, when US companies substituted equity by debt, especially by issuing corporate bonds. Consequently, between 1984 and 1990 and in the second half of the 1990s leverage rose dramatically. It also stands out that there were various periods when banks’ lending standards were extremely restrictive and one period, namely since 2000, when activity in the commercial paper market slowed down. Both events spurred corporate bond issuance in the past. If the usual pattern of the credit cycle holds, equity buybacks remain subdued until the economic expansion gains ground. As long as companies are willing to repair their balance sheets, net corporate bond issuance is also expected to be low. The analysis of the maturity structure of outstanding US and Euro corporate bonds shows a massive amount of redemptions for 2004 and 2005. On the other hand, while supply should remain weak during this period, demand for US financial assets by foreign residents is expected to remain strong. It is primarily driven by European investors and Asian central banks that pour huge amounts of money into the US capital market. A potential shift in the balance of supply and demand, however, is an important technical factor for the outlook for corporate bond spreads.
