Strange Daily JPY Negative Correlation with TOPIX

It is said that Japanese Yen (JPY) moves awkwardly in the market because JPY tends to be appreciated while Japanese economy indicates the sign of downturn at least in the short run. This trend is often perpetuated even in the middle run. This surprises majority investors observing JPY trends.

In the long run, this awkward trend of JPY is usually corrected to follow the major indices of Japanese economy, such as major Japanese corporate stocks, with their positive correlation as same as the other major currencies of OECD countries such as US dollar (USD). Nevertheless, the market almost always demonstrates the notable negative correlation between JPY and a major Japanese stock index such as Tokyo Stock Price Index (TOPIX) while the observers and the participants monitoring it.

Majority of these individuals monitor JPY with the USD, the most traded pair of JPY, so USD/JPY (USD value based on JPY) is frequently used for the main reference to scale the change in JPY value. The following regression analysis based on the Ordinary Least Squares (OLS) for the time series analysis assesses this phenomenon by regressing the log difference of daily USD/JPY on the log difference of daily TOPIX in the time series.

*** Please note that the positve correlation of USD/JPY means the negative correlation of JPY/USD, and vice versa ! ***

 

The sign is positive , and its t-value is 13.3 which is way higher than the Dickey-Fuller critical value t = 2.89.

Then, in order to determine whether this time series correlation is valid or just a coincidence with no statistical validity, the residuals (the error terms) of the aforementioned OLS are tested by the autocorrelation analysis as follows. The first difference of the residuals are regressed on the lagged residuals. The test is to detect whether or the error term is corrected itsself, so the eroor correction model is recognised.

The sign is negative, and its t-value is -26.43 so the absolute value is way higher than the Dickey-Fuller critical value 2.89, and then the error correlation model holds.

The equation of this estimates of the autocorrelation is expanded as follows.

Then it can be expressed as shown in the graph below:

This pattern of JPY mechanism is caused by the obsolete transaction system of the entire banking and monetary function. The obsoleteness is characterised by both the inefficient physical mechanical equipment of the currency transaction of money and assets among banks and investors and the rigid traditional bureaucracy of government, central bank, and private banks in Japan.

Whenever, the market participants switch their holding assets with the others, the system requires them to convert their assets to the national currency JPY before purchasing the alternative asset. Furthermore, due to the slow transaction in this inefficiency, there is a significant lag of exchanging different assets. Therefore, it consequently induces them to hold JPY cash in their transaction process.

In addition, majority Japanese citizens have a strong faith in holding cash and the middle to high income Japanese citizens have a remarkably high propensity of saving (This is why the majority share of the government bonds is owned by these middle to high income earners. They have a strong tendency to hold cash all the more when the value of stock, bonds, and other equities started being depreciated. This accelerates the appreciation of JPY during the downturn on the top of the obsolete system inefficiency.

By contrast, during the upward market, the short run JPY depreciation may seem to be depreciated when TOPIX rises. Instead of TOPIX affecting JPY, this case scenario is that the depreciation of JPY causes to stimulate TOPIX because of the two reasons. Japanese economy is a heavily export driving economy so JPY depreciation increases the export demand and the revenue of the exporters trading by means of foreign currencies. Another reason is simply because of the transactional motive of the traders attempting to mitigate the fincial loss of their revenue from the depreciated JPY by replacing JPY with the other foreign currencies or any available, safe, and stable assets.

Mr. Rishi Sunak will well remain in the history of Macroeconomics for his Hawkishness

It is a surprise to see such a Hawkish Chancellor of Exchequer after a decade of the Dovish regime in the world economic policy.  Mr. Rishi Sunak is certainly brave while being a little bit reckless.  It is certainly brave to reveal such a tough Hawkish characteristic . He puts emphasis on his prudent attitude toward balancing the budget. Even under the still anticipated downturn with a still remaining strong anxiety, he is willing to increase the overall taxation (generally slowing down economy) to balance the budget.  He claimed that, failure of balancing the budget eventually results in the rise of both the price inflation and the interest rate for bonds and mortgages is certainly alarming for economy.  

Regarding the usage of the term Hawk and Dove, it does not refer to diplomatic and military policies.  This term is uniquely used in macroeconomic policies related to neither diplomacy nor military.  In terms of macroeconomics, Hawk is tough and prudent whilst Dove is tolerant and loose.  It sounds similar to diplomatic and military policies but the implemented channels and the targets for setting these policies are different and unique in economics. Both have advantages and disadvantages.

Hawks are intolerant towards the enemies of the macroeconomic environmental stability such as the high price inflation (devaluing the income value and disturbs financial planning) and the rumour of distrust from investors and foreign exporters&importers.   They put emphasis on eliminating the root causes of the instability by tightening controls over balanced budgets and setting the central interest rate relatively high enough (plotting to consequently lower the high interest rate and stabilise the real income value). 

Doves are on the other hand tolerant for using loose policies to save individuals and their economic environment from the hardships (such as unemployment and lack of rescuing resources) even with some expected negative side effects.  They frequently claim for need of the looseness because the overall benefit covers the cost incurred by the negative side effect, and it should take place temporarily at least.   

Both are equally good as well as bad because both have disadvantages indeed. Hawks are remarkably unpopular during the unexpected economic downturn because Hawkish austerity is possible to be tough also on majority individuals suffering from the downturn, and then is likely to delay the recovery from the downturn.  Doves are blamed for their speculative projections often underestimating the cost of their policies so it is likely to misjudge of the timing of both imposing and cancelling their loose policies, and then their tolerance contains the high contingent risk of losing the administrative capability. 

Focusing on what Mr. Rishi Sunak is attempts to put into practice, he manages his policies by handing the fiscal policy-channels such as increasing tax rates to increase the inland revenue to reduce the national debt and various bond interest rates. He promises to consequently protect British citizens' income from either the high mortgage interest rate, the high price inflation, and lack of foreign investments with this policy implementation.  

The fiscal policy-channels are able to tune the different tax rate for various targeted segments of economic. Nonetheless, the fiscal policy always contains the mis-selection of the target sectors to increase the tax rate causing the systemic risk collapsing economy caused by penalising the certain sector's performance interrelated to many of the others. This Sunakian fiscal policy is expected to effectively handled to hopefully induce the positive aftermath.    

Mr. Sunak's policy is neither misguided nor irrational.  There are many worthy qualities accountable for encouraging the sustainable robust British economy. Especially, this seems to function for keeping the value of Great British Pound Sterling and secure the trust in the capital market and the foreign trades. Furthermore, his policy takes account of ordinary majority British citizens for securing their future real income value.  At the same time, the biggest concern is to determine whether or not this is the right moment to be tough as Hawk meanwhile the popularity of the looseness is still enthusiastically supported by the mass.

Having analysed these aforementioned aspects, Mr. Rishi Sunak's Hawkishness is neither absolutely good nor absolutely bad; but it is yet controversial.  Only the future might be able to provide the convincing appropriate judgement over his policy-aftermath.

GBP/USD is now 1.40 on 22nd February, 2021!!!

Hey! Cannae believe that GBP/USD is soaring as such!! 😮 Many investment banks indicated this is because of the effect of the newly distributed vaccine. ... I am still sceptical about the improvement of economic activity because it is really difficult to think that Brexit has induced such a rapid short term recovery (though it might be plausible to say Brexit does in the relatively longer term)! Well, this is a really tricky moment to forecast. Although some investment banks have predicted GBP/USD to be around 1.42, Bank of England still alludes possibly implementing a negative interest rate causing to depreciate GBP value at least for a short run.

Valkyrie/Walkure, 01 Jan, 2021

Dear all, Happy New Year!  I wish all the best for all of you visiting my blog! This is my first painting of this year.  I am going to practice using CLIP STUDIO PAINTING PRO more to get accustomed with this PC painting tool. 

The year 2021 will be still a challenging time period.  I am kind of feeling like wanting to become an invincible fighter with an unconquerable mind to overcome from these hardships.  The protection of gorgeous Walkure is believed to be complementary for those who fight against the hardship, isn't it. At least, it can be something to want to seek.

Market talks!

 

This is the FX chart today based on USD/EUR during these 5 days. It shows how market react to the outcome of the current significant events such as the outcome of the US election. Market is like an unimaginably complex computer which spontaneously calculates how demand and supply shift by means of needs and wants. Nowadays, not only banks and investors but also manufacturing companies of both major and small-medium sized participate in FX trades for financing their business. Therefore, market movements are really honest to instantly reflect the opinion of majority of economic agents reacting to the ongoing events and some events' aftermaths. It is completely up to your freedom of choice for what you think any way.
