Sterling depreciation raises inflation which requires monetary tightening. Interest rates are already rising and now must rise more sharply, with destabilizing effects on households, through mortgage rates, and on leveraged financial intermediaries.
|
||||
John Cochrane |

Both costs and benefits of short-term currency movements are over rated. And what to do about it? Absent a peg with ironclad fiscal commitment, propping up or devaluing the currency is not a wise policy.
|
||||
Francesca Cornelli |

The depreciation was due to concerns regarding the fiscal policy which will also affect the long run macro effects. In addition, the entire export policy of the UK has to be reassessed following Brexit.

It didn't seem to be a managed tradeoff for exports, but rather that it was an unintended adverse fiscal shock that the Bank of England was forced to partially accommodate. The BoE was also left with the task of managing significant spillover risks to financial stability.

Two issues: i) the pound fell endogenously in response to announced fiscal changes, which also have an effect on markets; and ii) any export benefits occur on a longer time scale than the market reaction to fiscal and exchange rate effects.

Exchange rate movements can signal both long term concerns about future government policy and the need for realignment between import and export prices. The former can be unnecessarily costly in contrast to the latter.

Question framed in a potentially misleading way. Currency depreciation in this case appears to be a symptom rather than a cause of economic problems driven by policy missteps that should be the focus of concern
|

Matteo Maggiori |

I think the costs of large and disorderly market moves can be large, especially if systemic financial institution get into trouble as a result. The benefit to the UK of a depreciation is hard to assess (the evidence is mixed in the literature) and probably significantly smaller.

Getting inflation under control is a main challenge in the current situation and weak sterling makes this more difficult.
|
||||
Jonathan Parker |
MIT Sloan | Bio/Vote History | ||
The value of sterling should decline given changes in inflation and in British economic institutions and growth. While it has overshot due to the BOE's low rates, the external exposures that would amplify this decline into a financial crises do not appear to be present.

This happened a century ago with the replacement of the British pound by the US dollar as the world's major reserve currency. Today there is no obvious alternative to the dollar, but a shift in reserve currency structure remains a possibility albeit unlikely.

John Cochrane |

Concern about debt sustainability can certainly drive currency lower and inflation higher. "Reserve currency" status is over-rated. EU governments, and Switzerland too can borrow at similar rates and quantities to US.
|
||||
Francesca Cornelli |
Northwestern Kellogg | Bio/Vote History | ||
If the concerns are linked to the feasibility of the fiscal policy (as it is in this case) then I would agree, but it depends on that point of view.
|
||||
Douglas Diamond |
Chicago Booth | Bio/Vote History | ||
Future depreciation concerns can become self-fulfilling if confidence is lost. This may be due to perceived future loose monetary policy or government debt monetization.
|
||||
Darrell Duffie |
Stanford | Bio/Vote History | ||
Is this a "trick question"? Reserve-currency benefits depend on stable prices and a well functioning government securities market, with government bonds that act as a safe haven. Concerns about government finances and debt sustainability clearly don't support those conditions.
|
||||
Janice Eberly |
Northwestern Kellogg | Bio/Vote History | ||
The stability and liquidity of a reserve currency rely on relative fiscal and monetary stability, as well as scale, for a global reserve currency.

There are two ingredients for a reserve currency: 1) a large economy and 2) a perception that the economy will be relatively stable in the future. Concerns over debt sustainability inject additional uncertainty. It is well known in finance that additional leverage increases risk.

A key factor underlying a reserve currency is trust. Trust is built upon sound government finances and sound policies.
|
||||
Sydney Ludvigson |
NYU | Bio/Vote History | ||
Lots of factors can come into play (e.g., even if debt sustainability is a concern for the reserve currency, it may be even more of a concern for all the conceivable alternative reserve currencies), but the UK experience and history should at least be instructive
|
||||
Matteo Maggiori |
Stanford GSB | Bio/Vote History | ||
A loss of investor confidence in the fiscal commitment of a reserve country to maintaining the real value of its debt repayments is the core threat to the status of that currency. At the core, a reserve currency is a fiscal commitment to providing a safe asset.

Reserves are held in safe assets. Safe assets must be safe in times of crisis. Times of crisis pose fiscal challenges for countries with fiscal imbalances and high debt levels. The debt of a country with little fiscal space to handle crises is not a good reserve asset.

Sterling used to be a reserve currency until the size of the economy and the rise of the dollar undermined it.

the global safe haven currency has enjoyed extra fiscal capacity over the past three centuries, but that status switches periodically, and high debt is one factor that can make a contry lose that status.
