I hadn’t touched a computer since last Friday, so I only heard the news Monday morning. While S&P’s move was a bit of a surprise, coming as it did on the heels of the agreement last week on the US debt ceiling, it wasn’t an absolute shocker. The magnitude of the US national debt – and more importantly, who’s holding it – suggests that the risk was always there.
Fundamentally though, nothing has really changed since last week or last month. I can’t help feeling that the ratings agencies are bolting the stable door after the horses have fled. They were roundly criticised and partly blamed for the CDO mess that caused the liquidity crunch in 2007-2008 – both in rating structured products at AAA grades as well as for failing to downgrade fast enough when it became clear that most of the stuff was junk. This is perhaps S&P’s way of saying never again, as the downgrade is a bit of a paper tiger.
What makes this all ironical is that because US government borrowing is all denominated in US dollars, the risk of default is effectively zero. Hence, I don’t know if there’s going to be any real impact on US debt issuance or investor appetite for US treasuries. Even as equities worldwide faced a sell-off, when I checked just now – as I suspected would happen – US treasury yields were down, not up as you would expect on a ratings downgrade. The news just provided investors an excuse to act on their fears over global growth, as equities have looked overbought to me and many others since early this year.
But flight to safety leads directly back to US sovereign debt. So you’ll have this paradoxical situation of the debt downgrade leading to higher demand for the very debt that supposed to be less credit worthy (and incidentally, higher demand for the USD). Go figure.
And before anyone starts blaming the Fed for treasury price movements, let’s note that QE2 ended last month and hasn’t been extended (yet). I’ll also note in passing that the ECB took the opportunity today to quietly expand their QE program, adding in Spain and Italy to the existing support they’ve extended towards Greek, Irish and Portuguese debt.
We’re truly living in interesting times.
