Projection
No statistical model we tested has beaten a simple no-change assumption on this series over the past 49 weeks of backtests, so gov.house does not publish a projection line here. What the history does tell us is how far the series usually moves:
| Over the next | Usual move (4 in 5 cases) | Range from today's 158.34 |
|---|---|---|
| 4 weeks | ±3.21 | 155.13 to 161.55 |
| 8 weeks | ±3.93 | 154.41 to 162.27 |
| 13 weeks | ±4.53 | 153.81 to 162.87 |

Rate-implied forward
Where the exchange rate would have to be for an investor to earn the same by holding dollars or the other currency, given today's interest rates: 3m forward 157.37; 6m forward 156.40; 12m forward 154.48. Shown as ◇ on the chart.
This is what the interest-rate gap prices in, not a prediction: in practice the spot rate has often moved the other way, and over a few months a simple no-change assumption is usually at least as accurate.

About this data
Daily noon buying rate in New York for the Japanese yen, in yen per US dollar, from the Federal Reserve's H.10 release, via FRED.
What it measures
How many yen one US dollar buys.
Why it matters
The wide gap between US and Japanese interest rates has made the yen one of the weakest major currencies of recent years, prompting Japanese intervention and appearing on the Treasury's currency monitoring list. Japan is also the largest foreign holder of US Treasury securities.
