Yen just hit a level not seen since 1986. That is a long time. Most people reading this were not even alive back then. Here is what is actually going on.
Yen Breaks Below 162
Japanese yen slid past 162 per US dollar Tuesday. Touched its weakest point since December 1986. USD/JPY climbed as high as 162.40 at one stage. Yen is now down more than 3% for the year so far.
This move reflects something deeper than just one bad day. Markets are doubting whether Japan can actually control inflation while other major central banks are still leaning toward tighter policy. That gap in approach is what keeps pushing the yen lower.
Japan’s Chief Cabinet Secretary Minoru Kihara issued another warning this morning. Said authorities stand ready to act whenever necessary. Same language used before. Markets have heard this script already and are watching to see if words turn into actual buying of yen this time.
Why This Keeps Happening
Traders increasingly think the Bank of Japan is falling behind. That basically means reacting too slowly to inflation, letting both prices and the weak currency drag on longer than they should.
BoJ did raise rates to around 1% recently. Highest since 1995. But markets only expect one more small quarter point hike by January. Meanwhile the Federal Reserve is still expected to possibly hike once or twice more, getting closer to 4%.
That gap matters a lot. Higher rates in the US make dollar assets more attractive than yen assets. Money flows toward higher yield. People buy dollars, sell yen. Gap between US and Japan rates keeps widening and that gap is the single biggest thing driving this pair right now.
Stock Market Boom Adding Pressure
Japan’s own stock market success is making things worse in an odd way. Nikkei has been on a record breaking run this year, pulling in foreign investors who want exposure to Japanese AI and semiconductor names.
Problem is many of those investors hedge their currency exposure. That means they sell yen to offset their stock purchases. More foreign buying of Japanese stocks actually creates more yen selling pressure on the side. Strange dynamic but it adds to the slide.
Will Japan Step In
Japan already spent tens of billions of dollars intervening back in April and May trying to support the currency. That means the government directly entered the market and bought yen to slow the decline.
Whether they do it again probably comes down to speed. Japan has tolerated a weak yen for long stretches before. What gets their attention is a fast, one way move. This recent slide has been fairly quick.
One thing worth noting. Japan has around $1.3 trillion in reserves available to fight a stronger dollar if they decide to use it. That is a serious amount of firepower. Question is timing, not capability.
For now 162 is the new line in the sand. Whether it holds or breaks further depends on what happens with US rate expectations and whether Tokyo decides talking is enough or whether it is time to act again.
