Roger J Kerr asks whether monetary policy should be tightened when the majority of the inflation pressures are coming from a single source, construction costs

 By Roger J Kerr

One could argue about why the RBNZ suddenly decided to concentrate on the inflation risks stemming from strong migration flows and lower than expected two and three year fixed rate mortgage interest rates on the residential property market.

The housing market was already showing signs of leveling off through the winter months as the number of days to sell has reversed from lower to higher.

However, whether they should be tightening monetary policy when the majority of the inflation pressures are coming from a single source, construction costs, is more of a fundamental argument.

There is no question that the resources pressures, thus price pressures in the building industry come largely from the unique situation of the Christchurch earthquakes re-build.

To what degree the RBNZ should be making an exception for a special circumstance is a moot point. In the past, the RBNZ have chosen to exclude one-off price increases for GST increases, rising global oil prices and Government policy changes from their inflation considerations, as long as the price increases did not transfer into wider second-round inflationary increases.

Should a special case be made for the Christchurch rebuild and therefore some of the first-round construction price increases be excluded?

If it can be shown that general wages and prices are not materially increasing across the economy as a result of the unique Christchurch situation, the RBNZ have a responsibility to consider an exception and adjust their inflation forecasts and monetary policy settings accordingly.

I am not advocating that the RBNZ should abandon their planned path to normalise short-term interest rates. Having warned some 18 months ago about the inflation risks associated with an economy expanding by 4% in 2014, I am not about to change my mind about rising interest rates.

However, given that the high exchange rate already has monetary conditions very tight in the economy, is there a risk that an extraordinary one-off event (Christchurch rebuild) causes monetary policy to become overly tight and the collateral damage to the export sector do not justify the means?

Under the old (now discredited by some) Monetary Conditions Index (MCI) measure of combining the exchange rate and interest rates together, current monetary policy settings are at the extreme tight end (refer chart below).

At 1400, the MCI Index is as high (extreme tight) as the peak in 2007 when overly tight monetary conditions (plus a drought) sent the economy into recession.

Expect to see two and three year swap rates push higher over coming weeks as more mortgage borrowers tap the attractive fixed rates on special offer and the currency comes back off its highs.

Longer term swaps rates will also be pushing up as the US bond market starts to recognise rising inflation (which Fed boss Janet Yellen is dangerously dismissing) as the one-off price decreases in the US over the last 12 months drop out of the annual figures.

PRECISELY...................We are all being punished because the three big suppliers of building materials have seen it fit to ramp up prices in excess of inlfation . 

We need to curtail immigration immediately to prevent the demand for houses and new builds spiralling completely out of control

AND whatsmore , where is this so-called inflation ? I personally have not seen it over the past 2 years , our hpusehold and business spending has remained level barring seasonal variations ion the cost of electricity  , increases in ACC and vehilce licences , which are relatively insignificant

I think you need to visit the concept of covert default

 

A sovereign can inflate away debt if the average interest rate on the debt falls below the growth in nominal GDP. (It doesn’t matter whether it’s volume growth or inflation driving GDP.)

 

New Zealand's most recent nominal ann. GDPE growth is recorded @ ~6.98%

 

The average NZ Government debt interest rate paid by term redemption bound taxpayers runs around plus or minus  5.05%

 

Australia is certainly in the frame for a round of covert default despite currency traders' best intentions to anticipate otherwise - read more

Good points Roger.

But.
If one area booms, and it's allowed to continue, what of connected industries.

Personally I think that's a great idea.  That means any one (or two) shooting stars can develop as _their_ industry booms, and the economic growth can positively flow to the rest of the economy without fear of everyone being punished for their success.

Yet by only taking out a couple of brief flash outliers (ie companies not steadily causing inflation) it doesn't cripple the tool, yet allows a degree of prosperity.

After all the tool is there to act as a governor on the speed, to stop things going like Auckland property is, in a self-feeding rush

We are actually in mild deflation currently.

I think you really need to enlighten the RBNZ about this. Why oh why they aren't listening to Roger is beyond comprehension.

I dont think that inflation has much to do with the ocr rises. The RBNZ needs to get the ocr back up before the game does not play properly. Leaving the ocr at 2.5% would have seen Auckland house prices carry on up and when real inflation turns up and the RBNZ has its hand forced, then forced sales in an under supplied market.
