The Ted spread, the difference between the three-month dollar London interbank borrowing rate and the yield on three-month US Treasury bills, is often used as a measure of perceived interbank lending risk. At close on May 19 it had dropped to 57.2 basis points, the latest point in a long decline that has taken it from a peak of 463bp on October 10 last year.
On September 12 last year, the last trading day before the collapse of Lehman Brothers on September 15, it stood at 134.9bp. Before the start of the general crisis in mid-2007, values of around 50bp were reckoned to represent business as usual.
Commodity market volatility, as represented by the Chicago Board Options Exchange's (CBOE) OVX measure of implied volatility in crude oil options, has also fallen, ending trading yesterday at 41.25 - slightly below the pre-Lehman figure of 45.75 on September 12 - after peaking at 100.42 on December 11. This is still, however, higher than the level the index reached before mid-2007, when it moved between 20 and 30.
The Merrill Lynch Move index, a yield-curve weighted average of the normalised implied volatility of one-month Treasury options, also dropped back to pre-Lehman levels, reaching 122.7 at close of trading on May 19, down from a peak of 264.6 on October 10. It finished September 12 at 125.4.
Two other indexes of market volatility remain slightly above their pre-Lehman marks. The CBOE VIX index of equity price volatility closed at 28.8 yesterday, compared with 25.66 on September 12, and the Deutsche Bank currency volatility index, which is based on the implied volatility of options on nine major currency pairs, closed at 13.89, still higher than the 11.503 level reported on September 12. However, both have fallen significantly since late last year: the VIX peaked at 80.86 on November 20, and currency volatility reached 24.2383 on October 27.
The news provides added weight to the "FedViews" analysis released yesterday by the San Francisco Federal Reserve Bank, which commented: "Not all economic news has been dire over the past couple of months, supporting the view that the economy might be close to its trough."
In particular, economist Bart Hobijn continued: "The financial sector is showing signs of stabilisation. We have seen the resumption of securities issuances in several financial markets that had come to a virtual standstill after September 2008. Stabilisation of financial markets and institutions, as well as fiscal and monetary stimulus, will provide momentum for positive economic growth by the end of this year."
