UK MPC model suggesting moderate easing package

Posted on Tuesday, July 26, 2016 at 12:22PM by Registered CommenterSimon Ward | CommentsPost a Comment

A model of the MPC’s historical “reaction function” suggests that the Committee will cut Bank rate by 25 basis points (bp) to 0.25% at its August meeting, based on current economic and financial information. The model forecast would be consistent with several members (Haldane, Vlieghe?) voting for more significant action but others (Forbes, McCafferty?) favouring “patience” or judging growth / inflation risks to be balanced.

A further possibility is a smaller rate cut (12.5 bp?) coupled with a modest QE programme (£30 billion over three months?) – such an approach has merits given uncertainty about the benefits / costs of moving rates towards zero. A less likely but more radical option would be for the MPC to move to an ECB-style dual-rate system, paying a “Bank rate” of 0.5% or 0.25% on the bulk of banks’ reserves but imposing a zero or negative rate on the top tier.

The “MPC-ometer” model attempts to explain the “average vote” of Committee members using information known before the start of each month’s meeting. If five members vote for a 25 bp rate cut and the other four for no change, the average vote is -14 bp (five-ninths of 25 bp). QE is allowed for by assuming that a 25 bp rate cut is equivalent to £75 billion of QE*. The model was estimated using historical data since the MPC’s inception in 1997.

The model’s inputs are grouped into indicators of economic growth, inflation and financial market conditions. Growth indicators include the quarterly change in GDP, manufacturing and services purchasing managers’ indices (PMIs) and consumer confidence. The inflation indicators are the deviation of current inflation from target, average earnings growth, consumer inflation expectations and manufacturing firms’ price-raising plans. Financial market indicators include short-term government bond yields, share prices, the effective exchange rate and the interbank / Treasury bill rate spread. The model also takes account of any vote dissents at the prior meeting and inter-meeting signals from individual members (such as Weale’s indication that he will vote to ease in August).

If the MPC changed policy only by moving Bank rate by 25 bp or adding / subtracting to QE in £75 billion chunks, the MPC-ometer would signal action if the forecast average vote moved above +12.5 bp (tightening) or below -12.5 bp (easing). The lower panel of the chart compares the historical fitted values of the model with the implied “unchanged policy range” of +/-12.5 bp, shown shaded. It can be seen that movements outside this range are usually associated with Bank rate changes or – since 2009 – expansions of QE.


The current model forecast for August is -21 bp, the lowest since July 2012, at the height of the Eurozone crisis and during a period of expanding QE. This forecast assumes that tomorrow’s second-quarter GDP release will show quarterly growth of 0.5%, in line with the consensus estimate. The key drivers of the large change this month are the post-referendum slumps in the PMIs and consumer confidence, and a fall in short-term government bond yields.

The forecast is unlikely to change significantly before the MPC vote on 3 August. Apart from the GDP release, a revision could be prompted by final PMI and consumer confidence readings – to the extent that these differ from flash estimates – or movements in markets.

The model is based on average MPC behaviour since its inception. It is possible that the current Committee membership has a different reaction function but there is no evidence that the model has “broken down” in recent years – the stability of policy since 2012 is in line with the average vote forecast, which has remained within the “unchanged” range.

*This assumption maximises the model’s historical fit with MPC behaviour; it does not imply that these alternatives have the same effects on economic growth and inflation.

Global economy firming at mid-year

Posted on Wednesday, July 20, 2016 at 02:22PM by Registered CommenterSimon Ward | CommentsPost a Comment

Available June industrial output data suggest that the global economy was picking up at mid-year, consistent with an earlier revival in real narrow money growth, which strengthened further last month. A positive view of economic prospects will be maintained here unless narrow money trends weaken, with such a weakening deemed unlikely.

The US, China and Russia have released June industrial output data, together accounting for 50% of the G7 plus emerging E7 aggregate tracked here. Results were above expectations in all three cases. Assuming no change in output from May in the other countries, six-month growth of G7 plus E7 output will have risen to 0.8%, or 1.6% at an annualised rate, the fastest since February 2015 – see first chart.

A mid-year pick-up had been suggested by global narrow money trends: six-month growth of G7 plus E7 real narrow money bottomed in August 2015 and rate of change turning points have led those in industrial output by an average of nine months historically. Real narrow money growth strengthened further last month, based on data covering the US, China, Japan, India and Brazil, together accounting for 67% of the G7 plus E7 aggregate. The current economic upswing, therefore, may extend through March 2017, at least.

Will Brexit affect monetary trends and the economic outlook? Narrow money is demand-determined, with demand influenced importantly by the spending intentions of firms and households, explaining why it leads the economy. The Brexit shock may dent confidence temporarily but spending plans should be supported by a post-vote fall in interest rate expectations. Narrow money trends, therefore, may remain solid, except (probably) in the UK. US narrow money in the latest week, ending 4 July, was 0.8% above its June average level.

As previously discussed, the economic significance of narrow money strength is often disputed on the grounds that zero / negative interest rates are putting downward pressure on the velocity of circulation. As long as the rate of change of velocity is less volatile than that of real narrow money, however, turning points in the latter should still signal future turning points in economic momentum. The value of a forecasting approach that identifies the future direction of economic growth should not be underestimated.

The relationship between levels of real narrow money and economic growth, moreover, can be partially restored by adjusting for a long-run downward trend in the rate of change of velocity. The red line in the second chart incorporates such an adjustment, while also allowing for the average nine-month lag between money and output changes. The fit of the relationship shows no sign of deterioration in recent years – industrial output growth was close to the “forecast” in June, with a significant pick-up indicated.

The green line improves the fit slightly further by incorporating the slope of the G7 government yield curve, which is widely monitored as a long leading indicator. The suspicion here is that the information content of the yield curve has been reduced in recent years by unprecedented market intervention by central banks. A flattening of the curve over the past year tempers but does not offset the positive signal for economic prospects from narrow money trends.

Why is UK note demand surging?

Posted on Tuesday, July 19, 2016 at 09:22AM by Registered CommenterSimon Ward | CommentsPost a Comment

The stock of UK notes and coin in circulation was growing strongly before the Brexit referendum and the rate of increase has risen further since the vote. This may indicate resilience in retail spending. Alternatively, the public may be “hoarding” cash in expectation of negative interest rates and / or restrictions on the supply of £50 notes.
    
Annual growth in notes and coin reached a seven-year high of 7.4% in April / May, remaining strong at 7.0% in June (month averages). Weekly statistics on the note issue indicate a further pick-up since the Brexit vote. As of last Wednesday (13 July), the stock of notes was 8.9% higher than in the corresponding week in 2015 – see first chart.


The annual change in real notes and coin (i.e. deflated by consumer prices) has displayed a significant contemporaneous correlation with the annual change in retail sales volume since the late 1980s (at least) – second chart*. The relationship, however, broke down temporarily around the turn of the century and during the 2008-09 financial crisis as worries about the banking system caused the public to hoard cash**. The Brexit vote is unlikely to have prompted similar concerns. Strong notes growth, therefore, may indicate that retail spending has remained solid since the referendum.


Alternatively, people may be hoarding notes not for safety reasons but because the Bank of England is expected to cut interest rates significantly, possibly even imposing a negative rate on bank reserves, forcing banks to start charging for operating current accounts. The Monetary Policy Committee has signalled that policy will be eased in August and the Bank’s chief economist, Andrew Haldane, has advocated a “sledgehammer” approach. Mr Haldane mused approvingly about negative rates in a speech last year and may wish to use the Brexit vote as an excuse to launch such an experiment.

Hoarding may also reflect increased demand for £50 notes due to uncertainty about their future supply. According to the Bank’s 2016 Annual Report, the value of £50 notes in circulation rose by 11.6% in the year to end-February, while lower-denomination notes increased by only 5.1%. Governor Carney confirmed in June that there are no plans to introduce a plastic version of the £50 note, fuelling fears raised by Mr Haldane’s earlier speech that the Bank intends to restrict the future supply of cash in order to create scope for interest rates to fall further below zero.

Chinese nominal GDP rebounds, money signal still positive

Posted on Friday, July 15, 2016 at 11:56AM by Registered CommenterSimon Ward | CommentsPost a Comment

Stronger Chinese monetary trends late last year suggested that economic growth would recover during the first half of 2016, contrary to consensus expectations of a further slowdown. Key indicators firmed through the spring but by less than had been expected here. Second-quarter GDP and June activity numbers released today were, on balance, more encouraging, while the monetary signal remains positive.

Annual growth of GDP in volume terms was unchanged at 6.7% last quarter but the more significant news was that nominal GDP expansion rose for a second successive quarter to 7.3%*, the strongest since the fourth quarter of 2014. A rebound had been signalled by a pick-up in money growth from mid-2015. Annual increases in narrow and broad money (as measured by “true” M1 and M2 excluding financial sector deposits) were little changed in June, with recent growth the fastest since 2010 and 2013 respectively – see first chart**.


June activity numbers were mixed. Annual growth of industrial output and retail sales value rose to 6.2% and 10.6% respectively in June, beating consensus expectations. Fixed asset investment, however, slowed further, with an annual value rise of 7.3%, close to a September 2015 low of 6.8% – second chart.

Capex weakness reflects the private sector component, which stagnated in the year to June – third chart. Prospects for private investment, however, are judged here to have improved. Industrial profits lead private capex and are rebounding on the back of stronger nominal GDP growth. A pick-up in growth of deposits of non-financial enterprises over the past year is a further positive signal – fourth chart.



An investment revival coupled with continued solid consumer spending expansion and an export pick-up driven partly by recent exchange rate depreciation may result in stronger volume as well as value growth of GDP during the second half, despite some reduction in fiscal stimulus.

*Corrected from 8.2% originally reported by Thomson Reuters Datastream.
**”True” M1 includes household demand deposits, which are excluded from the official M1 measure. Financial sector deposits are excluded from M2 because they are volatile and less relevant for assessing spending prospects.

G7 leading indicator rising before Brexit vote

Posted on Wednesday, July 13, 2016 at 09:08AM by Registered CommenterSimon Ward | CommentsPost a Comment

The OECD’s G7 composite leading indicator (CLI) strengthened in May, providing further confirmation that the global economy was picking up before the Brexit vote shock. The global impact of the shock is expected here to be minor and offset by a post-vote loosening of financial conditions – the forecast of a rise in growth during the second half, therefore, will be maintained, unless narrow money trends weaken.

The OECD was due to release May leading indicator data on Monday but instead announced that publication would be suspended until September, on the grounds that the Brexit vote was a “significant unexpected event, which is affecting the underlying expectation and outturn indicators used to construct the CLIs”. This is a strange decision: the OECD has never before suspended publication of its entire suite of indicators in response to a shock and it seems a stretch to argue that the Brexit result is more significant than some previous unexpected events (e.g. the 911 terrorist attacks)*.

It is, however, straightforward (if laborious) to replicate the OECD’s calculations to estimate the May data. The first chart shows published and estimated values of the “normalised” version of the G7 leading indicator – rises / falls signal that future GDP growth will be above- / below-trend. This fell steadily during 2015 and early 2016 but stabilised in April and is estimated to have risen slightly in May. The indicator, that is, suggests that growth was on course to move from below- to above-trend during the second half, before the Brexit vote shock.


The second chart shows an alternative version of the indicator designed to predict the level of industrial output rather than the ratio of GDP to trend. The six- and one-month changes in this indicator continued to firm in May, clearly signalling a coming rise in industrial output momentum.


The US component of the G7 indicator has been the main driver of its recent pick-up. The six-month and one-month changes in the US indicator strengthened further in May, confirming an earlier positive signal from faster real narrow money growth – third chart.


The Brexit vote result has the potential to depress the G7 leading indicator via impacts on business / consumer surveys, yield curve slopes and stock prices**. The MSCI All-Country World Index in US dollars, however, has already rebounded to above its level before the 23 June vote, while yield curve flattening has started to reverse. Any survey weakness should be mitigated by expectations of easier monetary policy and may prove temporary.

*The Japanese indicator only was suspended for two months following the March 2011 earthquake / tsunami.
**All G7 country indicators contain at least one business survey component. All except Japan and Germany include consumer sentiment / confidence. The slope of the yield curve is a component of the US, Japanese and German indicators. Stock prices appear in the US, Japanese, UK, French and Canadian indicators.
