The Swedish krona weakened sharply after the preliminary inflation figure for October was published and showed a larger decline than expected. The currency lost ground against both the US dollar and the euro, a movement that quickly became visible in the currency market.
The figures were presented by SCB, Sweden's statistics authority. Inflation fell more than had been forecast, a development that normally raises questions about how quickly the Riksbank may adjust its monetary policy. The krona's strong reaction immediately after publication suggests that the market interpreted the outcome as a surprise rather than an expected development.
It should be emphasized, however, that the underlying data is preliminary. The final figures have not yet been confirmed, and adjustments may therefore occur before the exact picture of inflation developments in October is established. The source material does not state the size of the inflation decline in percentage points or what expectations existed ahead of the publication. This means a full assessment of how large the surprise was cannot be made on the basis of the material currently available.
The currency market generally reacts sensitively to outcomes in inflation statistics, since these affect expectations about the future path of interest rates. Lower inflation can reduce the likelihood of continued monetary tightening, which in turn can make a currency less attractive to investors seeking returns. This is the mechanism that usually explains similar movements in the krona following earlier inflation releases.
The krona's weakening was at the same time visible against both major currencies in the comparison. That the movement occurred against both the dollar and the euro suggests the outcome affected the Swedish currency broadly, rather than merely reflecting conditions in a single currency pair. How long the weakening lasts, however, depends on whether the final figures confirm the picture from the preliminary publication.
The next steps will therefore be to follow both SCB's final inflation figures and how the krona develops against the dollar and the euro in the coming days. Only once the data is confirmed can it be judged whether the initial reaction in the currency market holds and what consequences the outcome will have for economic expectations going forward.
