Prime Minister Shinzo Abe recently won a landslide reelection in Japan. The victory had been widely anticipated, but the benefits of monetary policy stability is still being scrutinized.

As Abe first came to power, he pressured the Bank of Japan (BOJ) to undertake its largest and most aggressive easing measures in the country’s history. The central bank has been creating $70 billion monthly to purchase Japanese debt — an amount so massive for Japan’s economic output that it makes U.S. policy look tame. Shortly after the plan had been leaked, the yen lost roughly 20% of its value and boosted the perception that the stimulus would help Japanese corporations.

Unfortunately for other countries in the region, the rapidly declining yen made it difficult for those neighbors to export goods at competitive rates. Countries like South Korea were particularly hard hit. Granted, there may be exceptions. For the most part, however, Asian stocks have been among the world’s weakest while Japanese stocks have topped nearly all challengers.

As it stands in 2013, iShares All-Country Asia excluding Japan (AAXJ) has offered -7.5% in the same time period that iShares MSCI Japan (EWJ) has gained 20%. The dollar-hedged WisdomTree Japan Hedged Equity (DXJ) is up about 32%. Indeed, it’s difficult to see how Japan’s massive quantitative easing can be viewed as a net positive to Asian neighbors.

Nevertheless, some commentators are now making the case that Southeast Asia is benefiting from extreme stimulus by the world’s 3rd largest economy. Aaron Back at argues that the extra liquidity of money creation will eventually flow throughout the region, not only through direct investment, but also through large financial institutions with a global presence. Mr. Back suggests that the lenders can borrow at ultra-low rates domestically and then lend out the money at higher interest rates throughout Southeast Asia. He cites $8 billion having been spent in the prior 8 months by Mitsubishi and Sumitomo to build stakes in financial companies in Thailand, Indonesia and Vietnam.
