I have just spent the last 3 days at the NZ Association of Economists annual jamboree in Christchurch. It was well worth the time as it was a good opportunity to meet economists working in a wide range of areas and sub disciplines.

There were plenty of interesting papers on monetary policy, forecasting, environmental economics, migration, work and of course the housing market. There was a good mix of age and gender which added to the energy.

The keynote speakers were interesting with talks as diverse as climate change and the economics of sexual harassment.

The paper on Climate Change from Warwick McKibben is worth a look and the paper from Motu on Nutrient Trading provides a micro view of how trading in externalities might work at the local level. The work on allocating and trading pollution permits dovetails nicely with the work from Peter Barnes on reclaiming the commons and allocating rights to pollute which can be traded.

The general feeling on the housing market is that the boom is coming to an end but that it has been justified by low interest rates and the ability to ringfence losses from geared rental properties. I should add to this that migration and willingness to pay higher prices than locals has also contributed to the excessive rise in house prices. The banks have played their part in happily lending the required amounts and no doubt will be the first ones to notice any pullback from investors. This seems to have already started.

I would like to have seen some papers on behavioural economics as i think that is starting to build as an interesting field alongside new wave areas like neuroeconomics.

Economist is a dirty word in NZ due to the long hangover from the economic revolution of the 80s but i can report they are a good bunch….really

On June 11th the RBNZ intervened in the NZ$ by selling NZ$ around the US$0.7660 level in thin markets. This was followed up by another bout or two resulting in short term sell offs to US$0.76.

This action has create a fair bit of comment most of it apoplectic in nature focusing on the poor NZ central bank against the might of global speculators. The commentary uniformly blasted the RB and trotted out the story of how George Soros buried the Bank of England back in 1992.

Well this is one time i can say “i was there” as i was actually trading Stg at the time, with the regular trader lying on a beach in the Carribean. It was a crazy time to be in the markets but when you were the focal point of action that feeling was magnified. The Bank of England phone line was running hot as we called up to sell more and more Stg. The voice on the other end of the phone was resigned to the ship going down.

It duly did. The next day i had my biggest one day loss in 12 years of trading as the market all but disappeared and every customer was looking to trade. I remember my broker took me out to dinner at the casino in Park Lane to recover. Nice.

But the main point of this story is that Stg was way overvalued and stuck in the ERM where it was required under the Maastricht Treaty to keep the Pound above a certain level which was DM2.7780.

So the Old Lady was just doing her job. She wasn’t taking on Soros or the market but just fulfilling legal obligations. Soros made a bet that the UK would have to pull out of the ERM and that was a political action and you can be sure he would have done his homework there.

So it is very different to what we see when the BOJ intervenes in the Yen at 100 or 145 where there is no legal cap but an extreme extension in rates.

The RBNZ action falls into this camp. The NZ$ is appreciating well beyond fundamentals based on the current account deficit, PPP comparisons and problems for the export sector to sell its goods. It is also suffering from carry trade side effects which are causing a huge inflow of short term investment to take advantage of high interest rates.

Its intervention is justified on those grounds. The NZ$ should be trading around US$0.60 which is just above its long term average. Of course currency rates can run way beyond what might be considered justifiable and for some period of time.

The Great Game continues in the global financial markets where the US sells it paper to trading nations such as Japan and now China in return for goods. One day this game may stop and the US$ will go into freefall.

The same could happen to the NZ$. I would say the RBNZ intervention is justified though how effective it is remains to be seen. Jeff Gamlin at the NBR is quite positive on the profit implications and it’s certainly a good long term trade to buy some foreign reserves. They should be selling as much Kiwi as possible!

As it happens intervention usually works if the intervening bank has some justification. Remember currency speculators like to make money. They don’t care whether it’s up or down.

The RBNZ is in a tight spot regardless of what Grant Spencer, the Deputy Governor , says. They will need a bit of luck to get this right and will need to continue intervening if required at higher levels like 78 and 80. I think though they will be safe there as people are starting to feel the pinch of higher rates.

Also yesterday the Japanese Minister of Finance weighed into the fray with some well placed comments. The Japanese are the experts in intervention and jawboning the currency. That shot across the bows should not be ignored.

I’ve been following the spread of microfinance for a while and have been getting involved with Kiva which has been a great experience. I have also noted the rise of social lending businesses such as Zopa, Prosper and even Facebook. Jason has written a good piece on the rise of new forms of financing.

What interest me further is whether all finance can move to a P2P platform and seriously eat into the major lending markets currently controlled by the commercial banks.

I think it could do. This crosses the web with money and complimentary currencies.

Remember that anyone can create “money” if they really want, it just can’t be in the form of bank notes issued by the Reserve Bank. Commercial banks create bank loans by a simple bookkeeping entry. Only 2% of the money supply in NZ is in the form of notes and coin so banks don’t actually hold any money other than a bit of cash.

My point is that P2P finance could take off in a very big way once we get the hang of it. My guess is that the firms currently involved don’t realise how big this could be.

Expect the central banks to cast their beady eyes over these operations once they get a roll on. For now it’s just some web bizness but this feels like 1694 all over again.

Oh dear it seems as if Bear Stearns may be in a little trouble as it coughs up $3.2bln to support one of its hedge funds exposed to the US subprime market.

This is not good news at all but the market has been through this before with the Long Term Capital meltdown in 1998 and of course the 1995 collapse of Barings Bank by Nick Leeson. So it won’t be in complete panic but this is a big move to Bear Stearns and perhaps just a taste of what can go wrong when the music stops.

Hedge funds are heavily leveraged and so when a big move goes against them the losses can be astronomical. In theory risk models are supposed to flash warning lights at set points but the reality is that these models are not foolproof (after all we designed them) and traders can often disguise bad positions. And from my experience all risk is underpriced since it is based on average volatility and not the heavy meltdowns that come with increasing regularity.

The last 10-15 years has seen a huge amount of money created by the worlds’ banks and much of that finds its way back into the financial markets to be invested or used as speculative margin. The numbers are so huge that the Fed in the US has decided it would rather not publish money supply numbers anymore.

So when the market goes into reverse it can cause major losses which have knock on effects around the whole system.  It will be interesting to see how this situation pans out but at some point there will be a serious contraction unless new demand can be conjured up.

There has been a lot of hand wringing over the recent Reserve Bank’s intervention in the currency market. So what’s the story here?

Well the RB has a clear mandate to keep inflation, as measured by the CPI, between 1-3% on an annual basis. According to them they also say that,

“The Bank is required to ensure that, throughout the economy, money works as well as possible as a mechanism for making transactions, storing value, and keeping account.”

So let’s say they are also responsible for price stability in a general sense i.e. no serious asset bubbles or major deflationary shocks.

So how are they doing?

Since 1998 the CPI has risen 20.7% to December 2006. So an average of 2.5% per annum which is within the prescribed band.

But the key worry, or so they keep repeating, has been the housing market which in the same period has risen 143%.

So what have they done about it?

From Mar 04 to Dec 06 they raised interest rates by 2%, from 5.25% to 7.25%. That doesn’t sound like a great deal by historical standards and clearly has not had any impact.

From Mar 04 to Mar 05 rates went up 1.5% as inflation took off towards 3%. However, they stopped when they should have kept going. When CPI hit 3.4% and stayed above, the bank should have got really serious and jacked rates up very quickly.

They didn’t. CPI was above 3% from Sep 2005 to Sep 2006 and they moved only 50bp. This was their big mistake. With house prices on the march as well they should have had rates up to 8% by June 06. They are a year behind the curve and that could cause some major problems.

Alan Bollard has been soft in his approach and this may well stem from the false comfort that low global rates has brought. The great inflation crush of the late 1990s has seen global rates fall into ranges not seen for many a year. Central bankers have been playing in a very small range and have been lulled into a false sense of security.

All around us we witness the asset price bubble caused by cheap global credit. The Japanese are still at it pumping out cheap yen that no one really wants. This is a major disaster waiting to happen. We’ve seen it before when USD/JPY fell to 79.65 back in 1995 on the back of US trade concerns and Asian Central banks dumping their US$. For now the flow out of the yen and into the kiwi continues with a rise of over 15% in the last 6 months.

Yesterday Winston Peters called for an amendment to the Reserve Bank Act asking that the Reserve Bank take a more rounded approach to managing monetary policy. I have to agree with him that a major review is needed and that simply using the OCR to control the economy is not working.

Submissions for the inquiry into a future monetary policy framework close on 19th July. I will post my submission up here in due course. It’s a great opportunity to throw open the arcane nature of our monetary system and make proposals that may lead to a more productive and stable economic system.

Following on from my previous piece I have just viewed a couple of interesting videos projecting how the web may develop in the future courtesy of Richard MacManus.

Whilst there is a certain amount of PR spin and product placement going on here they are both worth a look at if you have a spare 15 minutes. As i noted previously it is reminiscent of the 1920s and the media battle that took place from there on. Same stuff, different technology?
