The path of the potential pace of the JPY decline may still be underestimated by markets, which continue trading the JPY long.
While the 10% USDJPY advance from September lows looks impressive from a momentum point of view, it may no thave been driven by Japan’s institutional investors reducing their hedging ratios or Japan’s household sector reestablishing carry trades.
Instead, investors seemed to have been caught on the wrong foot, concerned about a sudden decline of risk appetite or the incoming US administration being focused on trade issues and not on spending. Spending requires funding and indeed the President-elect Trump’s team appears to be focused on funding. Here are a few examples: Reducing corporate taxation may pave the way for US corporates repatriating some of their USD2.6trn accumulated foreign profits. Cutting bank regulation could increase the risk-absorbing capacity within bank balance sheets. Hence, funding conditions – including for the sovereign – might generally ease. De-regulating the oil sector would help the trade balance, slowing the anticipated increase in the US current account deficit. The US current account deficit presently runs at 2.6% of GDP, which is below worrisome levels. Should the incoming government push for early trade restrictions, reaction (including Asian sovereigns reducing their holdings) could increase US funding costs, which runs against the interest of the Trump team.
Instead of counting on risk aversion to stop the JPY depreciation, we expect nominal yield differentials and the Fed moderately hiking rates to unleash capital outflows from Japan.The yield differential argumenthas become more compelling with the BoJ turning into yield curve managers. Via this policy move, rising inflation rates push JPY real rates and yields lower, which will weaken the JPY. Exhibit 12 shows how much Japan’s labor market conditions have tightened. A minor surge in corporate profitability may now be sufficient, pushing Japan wages up and implicity real yields lower.
JPY dynamics are diametrical to last year . Last year, the JGB’s “exhausted”yield curve left the BoJ without a tool to push real yields low enough to adequately address the weakened nominal GDP outlook. JPY remained artificially high at a time when the US opted for sharply lower real yields. USDJPY had to decline, triggering JPY bullish secondround effects via JPY-based financial institutions increasing their FX hedge ratios and Japan’s retail sector cutting its carry trade exposures. Now the opposite seems to be happening. The managed JGB curve suggests rising inflation expectations are driving Japan’s real yield lower. The Fed reluctantly hiking rates may keep risk appetite supported but increase USD hedging costs.Financial institutions reducinghedge ratios and Japan’s household sector piling back into the carry trade could provide secondround JPY weakening effects
