As argued in previous posts, current exceptional circumstances justify action by central banks to boost broad money supply growth to 10% or so temporarily in order to support an economic recovery. For this reason, the asset purchase schemes introduced by the Federal Reserve last autumn and the Bank of England this month are welcome.

The scale of the expansion of the Fed’s buying programme announced yesterday, however, threatens to push money growth well above 10% for a sustained period. While US recovery prospects are further enhanced, so is the medium-term risk of higher inflation and market disruption as the Fed is forced to withdraw unprecedented liquidity support at short notice.

Since last autumn the Fed has bought $241 billion of commercial paper, $44 billion of agency securities (i.e. issued by Fannie Mae, Freddie Mac and the Federal Home Loan Banks) and $217 billion of agency mortgage-backed securities (MBS). The total of $502 billion amounts to 6.1% of the M2 money supply and 4.4% of the broader money measure discussed in an earlier post.

The Fed had scope to buy a further $339 billion of agency debt / MBS under previous plans. It has now expanded the buying programme by up to a further $1.15 trillion, comprising $100 billion of agency securities, $750 billion of MBS and $300 billion of Treasuries. Future purchases could therefore total $1.489 trillion – 18.0% of M2 or 13.0% of broad money.

M2 grew by 9.8% in the year to February, while the broad money measure rose by 6.5% during 2008. The Fed may not utilise its full buying potential but if it did annual M2 / broad money growth could rise to 15-25%. Such rapid expansion is neither necessary for an economic recovery nor desirable for medium-term inflation and market stability.

The 138,000 jump in claimant-count unemployment in February appears to represent pay-back for surprisingly modest increases in earlier months.

The rise brings the cumulative increase since the low in January 2008 to 596,000. This is larger than at the equivalent stage of the 1970s labour market recession but below the rises in the early 1980s and early 1990s – see first chart.

A similar analysis for job vacancies gives a slightly different message: the decline from the peak in March 2008 is greater than in the early 1990s recession but is trailing the falls in the 1970s and 1980s – second chart.

These earlier episodes indicate that vacancies are unlikely to bottom before October 2009 at the earliest, while unemployment may continue to rise well into 2010.

Fourth-quarter US flow of funds accounts, released last week, confirm that broad money is growing at a respectable pace and has picked up in inflation-adjusted terms. Corporate monetary trends are healthier than in the UK and Eurozone, suggesting less pressure for business retrenchment.

The flow of funds accounts permit a more thorough analysis of broad money trends than is possible from weekly and monthly money supply releases. First, the accounts provide information on all the components of the old M3 – discontinued in 2006. Secondly, an adjusted M3-type measure can be calculated excluding money holdings of quasi-banks, which have been boosted by the financial crisis. Thirdly, this adjusted broad money measure can be broken down between households, non-financial business and financial institutions such as insurance companies and pension funds.*

Annual growth in adjusted broad money stood at 6.5% at the end of 2008, below a 9.9% December rise in the narrower M2 aggregate but above a 3.8% rate of increase of the equivalent UK measure (adjusted M4) – first chart. The 6.5% expansion was down from 7.6% at the end of the third quarter but a sharp fall in consumer price inflation resulted in real growth accelerating from 2.5% to 6.4%, implying greater monetary support for the economy in 2009 – second chart.

The 6.5% aggregate increase breaks down into growth of 5.3% for households, 6.2% for non-financial business and 13.9% for financial institutions – third chart. This suggests less pressure on non-financial business liquidity than in the UK and Eurozone: UK M4 holdings of private non-financial corporations fell by 4.7% in the year to January, while Eurozone non-financial corporate M3 rose by just 1.8% – fourth chart.

The reclassification by the Office for National Statistics (ONS) of the Royal Bank of Scotland and Lloyds Banking Group as public corporations will be a big help to the efforts of the chancellor, Alistair Darling, to limit fiscal red ink. The banks’ underlying profits will be booked as public sector income, significantly reducing net borrowing.

At first sight this looks odd since the banks suffered a combined operating loss before tax of £49.0 billion in 2008 and may remain in the red in 2009. ONS guidance, however, indicates that the profits definition to be used will exclude dealing/investment losses, credit impairments and goodwill write-downs. Profits before these deductions were a combined £27.7 billion in 2008. (The ONS figure could be lower because of other adjustments, e.g. excluding undistributed income of foreign subsidiaries.) RBS and Lloyds are to be included in the public sector from 13 October 2008.

The chancellor is widely expected to announce a large upward revision to his public sector net borrowing forecast of £118 billion in 2009-10 in next month’s Budget, reflecting a much deeper recession than projected by the Treasury last November. The average independent projection is £128 billion, according to the Treasury’s monthly survey of forecasters. The inclusion of the banks’ profits, however, implies that Darling could announce little or no increase.

The effect, of course, is entirely artificial: although not included in public borrowing, the losses suffered by the banks are real and have been reflected in the value of the government’s shareholdings. With no improvement in the public sector’s true financial position, the classification change does not create additional fiscal “room for manoeuvre”.

The ONS previously announced that the reclassification of the banks would boost public net debt by between 70 and 100 percentage points of gross domestic product from 47.8% currently.
