I've been really baffled by the high yen over the years since it would seem to me that a country like Japan that's got a huge government debt and stagnant economy would be seeing its currency fall in value, not rise. It even seems that natural disaster sends the yen value up, too!
I'd really like to hear from others here who know what's going on. My current theory is that this is because of the unbalanced inward/outward foreign investment situation where Japan has invested heavily overseas for decades but relatively little foreign investment is making its way into Japan. This means that the income (or future expectation of such) from the Japanese foreign investments is coming back into the country and pushing up the value of the yen in the process. When natural disaster hits, Japanese insurers have to liquidate their overseas investments and this also pushes the currency higher.
Am I right? Is this the fundamental reason behind the high yen?
If so, then Korea'd better pay attention, don't you think? I was at a presentation this week where it was said that inbound FDI was only $5.3 billion last year but that outgoing FDI hit a whopping $23 billion. This is a long-term trend and if Korea keeps this up, isn't Korea going to find itself in the same boat as Japan eventually?
Or am I all wrong about this?

Regarding Korea, the impacts are already felt at the financial, insurance, or industrial levels.
At the FDI level: more than a few Western companies are weighting their future in the archipelago. There's a trade off between security issues, and Korea is getting a closer attention (Kim Jong-il and co almost seem safe compared to a nuclear plant located on the very seashore of a tsunami prone era, and on a very active seismic fault). Typically, these days, regional HQs may move from Tokyo to either Seoul or Singapore.


THAT sounds like a new discussion thread!!!
...details please! ...I look forward to seeing your post ^.~

Stephane - Speculation might be a small factor, but it's not the main cause of the long-term Japanese high yen problem. That's been going on for WAY too long to be blamable on that. Here's a chart that shows what I mean:

BTW, here's the presentation from the forum I was at this week which got the gears moving in my head to initiate this discussion.

I just saw this discussion -thanks for posting the question, Steven. I was wondering the same thing myself, but lack all but a VERY basic finance-related background. AND, thanks "guys" for providing a few answers ^.^
Permalink Reply by Ondrej Slechta on March 26, 2011 at 3:39am The endaka (円高) phenomenon has been attracting attention since late 1980s as it often seems to contradict economic theories.
Economics is not an exact science and impact of many variables is not easily testable and measurable. This is complicating study of endaka in terms of differentiating between short run and long run as 1990s and 2000s brought a series of short run events which interrupted LT trends.
First of all, in terms of short run view, Steven is right when linking repatriation of yen to currency strengthening. This has been repeatedly happening for several reasons during the past 20 years and it is one of the main driver behind every short run yen appreciation. For instance:
- Japanese banks were repatriating investments in the late 1980s and during the 1997 crisis in anticipation of increase in bad debt levels
- Japanese private investors were converting their assets to yen during times of economic slow-downs to create a "safety cushion"
- economic turbulences in the West resulted in anticipation of drop in interest rates in the hit regions which led to massive unwinding of carry trades
- yen was perceived as a relatively safe currency during the recent turmoil in Europe and the USA
- as mentioned above, following the recent events insurance companies are pulling back their foreign investments as they will be paying most if not all the proceeds in yen
I don't have a fixed view on the long run part of the picture though. Dividend payments seem to mostly fit into the short run picture.
So just a couple of ideas:
One potential driver for endaka periods was most likely changes in real (vs. nominal) interest differentials
Based on Harrod & Balassa's productivity differential model, another driver could have been increase in productivity within export oriented part of the Japanese economy
Yet another simple explanation is that the markets were consistently over-stating Japan's ability to return to growth and accumulated yen holdings in expectations of further future appreciation which led to overpricing yen.
Some researchers also point to negative correlation between the yen rates and energy prices.
Most likely the long term trend is a combination of all the above drivers (and some more).
As for Korea, I do not believe Korea would be experiencing a kind of long term Korean endaka (i.e. "원고" - just conceived the term :-) for the same reasons as outlined above. As of today KRW is in a different situation compared to JPY as it is not a major international and freely convertible currency. Correlation between USD/KRW, USD/JPY and major events also suggests a slightly different dynamics.

Thanks, Ondrej.
It's interesting that your link the repatriation of yen to a short-term view. Perhaps I'm showing ignorance here, but I'm not sure I can agree with you this.
Sure, short-term appreciation is surely the result of short-term repatriation. But I'm talking about the long-term imbalance between the over-investment by Japanese companies overseas and underinvestment in Japan itself by Japanese companies AND foreign companies. This leads to the expectation that Japan will have to buy yen to pay themselves on income from overseas assets or to liquidate those overseas investments over a long period of time, and perhaps the long-term high yen is in anticipation of this, no?
I can see how high productivity in the export orientated part of the Japanese economy could be a small factor, but the trend in Japan for a long time now has been to move industry out of the country, which reinforces my point in the previous paragraph and reduces the effects of the alleged ultra-high productivity within Japan itself.
I have no idea why yen rates vs. energy prices, interest differentials or market over-expectation of future Japanese growth would be anything but short-term phenomena that could just as likely go the other way. I would also point out that whether or not the Korean won is freely convertible should also not be a long-term trend factor.

I see a couple of issues in the above hypothesis. First of all, 2 following assumptions are made:
- "all repatriated dividends are exchanged to yen" - this is not the case because the companies often use profits from overseas operations to fund further foreign expansion without converting the proceeds to yen. Also, many Japanese companies are listed on non-Japanese exchanges and pay dividends in other currencies. Lastly, even if the dividends are paid in yen, they would be partially converted back to foreign currencies by foreign investors or Japanese investors seeking currency diversification.
- "capital flows attributable to repatriated dividends always off-sets all other capital flows (carry trades, profit taking by foreign investors, trade etc.)" - I don't have any numbers at hand but I don't think this is the case as if it was, and if yen's fundamental value was getting weaker with net FDI outflow (and expected dividends repatriation), Japanese companies would stop investing abroad to strengthen their competitive advantage (i.e. no FDI > no dividend repatriation > weak yen).
I do not see this happening. In fact, the opposite is true. If we take a look at the other side of the coin and assume that net FDI receivers would see their currencies plummeting in the long run due to (expected) dividend repatriation, we would see all emerging markets currencies constantly dropping against currencies of main investors. Evidence suggests the opposite is happening, eg. there has been a long term upward trend in case of all major CEE currencies yet these CEE countries are net FDI receivers.
In fact, Japanese and Korean companies invest abroad to hedge themselves against appreciating yen and won. So, rather than seeing appreciating yen/won as something that is de facto caused by FDI and expected dividend repatriation, I see increase in outbound FDI being the result of local (Japanese, Korean) currencies appreciation. The more yen and won will appreciate, the more will the Japanese and Korean companies invest abroad to retain their price competitiveness and to prevent their profitability from eroding.
